Industrial Gearboxes: Types and Applications

Posted on by

For industrial processes, motors and other driving devices supply mechanical power to components to perform specific tasks. The amount of power provided can vary, which may at times be a higher power or speed that other components down the line can safely handle. Industrial gearboxes take the mechanical power and modify it so that the speed, torque, or other properties match better the operational power required for processes.

Gearboxes rely on the gear’s teeth and their orientation to modulate the power. Typically, straight teeth on the gear provide lower speed for applications, while a gear with spiral (helical) teeth offers higher speeds. Thus, a company has different gearboxes to select from based on their operational needs.

Types and Applications

Helical Gearboxes

Helical gearboxes have spiral teeth as the gearbox is fixed at an angle. This angle allows for more teeth to interact with each other in the same direction. As a result, this type of gearbox provides lower power. It may be found in elevators, coolers, conveyors, extruders, and heavy industrial applications.

Bevel Gearboxes

Bevel gearboxes have straight and spiral gear teeth. They are standard gearboxes for automobiles and power plants.

Bevel Helical Gearboxes

Bevel helical gearboxes have gear teeth on a cone-shaped surface as the teeth are curved. This type of gearbox is placed on non-parallel shafts as it provides rotary motions. Mining and quarry applications commonly have bevel helical gearboxes.

Worm Gearboxes

A worm gearbox has a wider wheel breadth. A screw thread, called the worm, on the axis meshes with the wheel’s teeth along the peripheral edge to turn the wheel. For industrial applications, the work gearbox is used in conveyor belts and lifts. They are also found on guitar tuning instruments.

Planetary Gearboxes

Planetary gearboxes get their names due to their designs that are similar to the solar system. For example, a center gear is like a sun as planetary gears rotate around the center mesh gear and a ring gear. Planetary gearboxes are found in cranes, lifts, and many machine tools.

There are many additional gearboxes other than the ones mentioned above. The gearbox may be specially designed for a specific operation, such as a crane duty gearbox made for construction and mining applications.

Gearbox Operation

Keep in mind that all gearboxes work in a very similar fashion. Gears will rotate based on the directional orientation of the power input and the gear’s direction. The speed and torque output can change depending on the size of the gears and the number of teeth on the gear wheel. So the lower the gear ratio, the higher the speed and less torque, while the higher gear ratio provides a lower speed and higher torque.

Industrial gearboxes are designed out of durable and strong materials to handle daily operations for extended periods. However, they may undergo excessive wear and tear as well as experiencing warning signs of potential malfunctions. Therefore, they should undergo regular inspection and maintenance to ensure the gearbox runs at its optimal level.

6 Considerations When Choosing a Coupling

Posted on by

Couplings are used in virtually every piece of power transmission equipment. Connecting motor and gearbox/reducer shafts to conveyors, pumps, compressors, and other machinery transmit torque while absorbing vibration and facilitating disassembly and maintenance.

The Importance of Coupling Selection

Whether designing new machinery or performing maintenance on something that’s seen years of service, it’s vital to use the proper coupling. But, unfortunately, choosing the cheapest or the best delivery is a recipe for performance problems and premature failure.

What’s more, when replacing a failing coupling, recognize that the OEM may not have specified one of the best quality. A coupling more appropriate to your application may last longer and lower your maintenance costs.

So with that background, let’s look at what your coupling supplier needs to know so they can recommend the most suitable product.

1. Torque and Speed

Handling these is the primary role of the coupling. Your coupling supplier needs to know both. Note that couplings are designed with an overload capability, typically 200% of the catalog torque limit, to accommodate start-up loads.

2. Service Factors

Where will the coupling be installed, and what conditions will it see? For example, if it’s going outdoors, exposure to UV, ozone, low temperatures, and moisture likely take elastomeric couplings out of contention. Ask for couplings proven in your application and take manufacturer recommendations into account.

3. Space Available

The two factors are the gap between the shafts and the clearance around them. Some couplings, especially elastomeric units for high power and torque applications, have large outside diameters, so identify any restrictions.

When considering space constraints, you may encounter “torque density” or “power density.” This is the rated torque divided by the OD. Gear couplings have some of the highest torque density numbers.

4. Precision Required

In the context of couplings, this refers to:

  • Tolerance for angular and offset misalignment (you may need to trade one for the other)
  • Backlash (a key consideration in precision motion control)
  • Windup (technically, torsional deflection)

For each of these, determine the limit of what’s acceptable and communicate it to your supplier.

5. Accessibility and Maintainability Considerations

If access to the coupling is difficult, it’s essential to select for long life, low maintenance requirements, and ease of repair/replacement. For example, avoid couplings that need lubrication (like gear couplings) and consider repairable ones by replacing only the flexible elements. (Grid coupling elements are often the least expensive.)

6. The Vendor

Find a vendor that works with a long list of coupling manufacturers and understands what your application needs. Ask about availability, stocking policies, and delivery: when a coupling does go bad, you want to know you can get a replacement quickly! Consider price only once you have candidates that will meet the performance requirements.

Get the Right Coupling for the Job

Shaft couplings may appear inconsequential, but that’s only until they fail. When choosing new or replacement couplings, consider all aspects of the application and share these with your vendor. Kor-Pak works with leading coupling manufacturers and can advise on what you should use. Contact us to get started.

Crane Inspections: When, Why, and How?

Posted on by

On any job site, safety must always be the most critical consideration. Statistics show that for 2019, more than 5,000 workers died while doing their jobs. 20% of these fatalities were in the construction sector, highlighting the need for regular on-site equipment inspection.

Cranes are an essential piece of equipment on any construction or manufacturing site. Therefore, site workers must follow safety guidelines and regulations correctly. This includes scheduling both frequent and periodic inspections.

In this blog post, we will highlight the when, why, and how of crane inspections. So read on!

Requirements for Crane Inspections

As per the 1910.179 standard from the Occupational Safety and Health Administration, ASME B30.2, and State Regulations, several requirements for carrying our satisfactory crane inspections are required.

A routine crane safety inspection schedule for cranes is essential to enhance workplace safety. Therefore, before the initial use of a crane, a full inspection is a must.

Only qualified OSHA inspectors are authorized to perform crane inspections. There are two types of inspections with regards to cranes: frequent inspections and periodic inspections.

At Kor-Pak, we offer a comprehensive array of Overhead Crane Services, including thorough inspections. On completion of inspections, a full written report is provided listing all deficiencies and recommendations.

What You Should Inspect Frequently

There is a range of inspections that should take place regularly, for example, weekly or monthly.

These include:

  • Cracked or deformed hooks
  • Maladjustments that interfere with normal operations
  • Leakage in hydraulic systems, pumps, valves, etc.
  • Defective hoist chains
  • Wire rope reeving system issues

At Kor-Pak, we provide repairs, modernizations, upgrades, training, and 24/7 support. We also prove a complete line of cranes and hoists for various industrial applications.

What You Should Inspect Periodically

Periodic inspections should occur at least several times a year. At each inspection, it’s essential to check on the following parts:

  • Loose rivets or bearings
  • Worn tires
  • Unsafe power plants
  • Brake and clutch system issues
  • Wear to chain drive sprockets
  • Overstretch of chains
  • Electrical apparatus issues
  • Inaccuracy in indicators

To ensure the proper maintenance of your crane, both frequent and periodic inspections should be scheduled into your calendar well in advance.

Your crane equipment’s age and current condition will also play a part in determining how frequently you should carry out inspections.

Schedule Regular Crane Inspections

Cranes are responsible for various jobs within the construction and manufacturing industries. They are beneficial for lifting heavy loads.

As with any other type of equipment, cranes can experience wear and tear over time. The above crane inspection checklist includes essential features of a crane that a qualified OSHA inspector should inspect.

Everything You Ever Wanted to Know About Storm and Parking Brakes

Posted on by

Mounting cranes on rails increases their utility in loading/unloading and other material handling tasks. However, it also creates another potential hazard: the risk of uncontrolled movement. Tall cranes used outdoors, especially in coastal regions, are vulnerable to high winds and wind microbursts. Earthquakes are another possible cause of unexpected motion in many locations, and the risk of collision with forklift trucks and similar machinery is ever-present throughout industrial and logistics operations.

Uncontrolled crane movement can be devastating, as is evident in a 2008 video of a crane collapse in Florida. It can disrupt operations, require expensive repairs and even cause loss of life. This is why storm and parking brakes should be considered essential on rail-mounted equipment. Here we explain these, outline how the various types work, and discuss when each should be used.

Rail Clamps and Wheel Brakes

Storm and parking brakes for rail-mounted equipment act either on the rail or on the wheels. The two categories are rail clamps and wheel brakes.

As the name suggests, clamps clamp onto the rail. This makes them appropriate for static situations where they act as parking brakes. In contrast, wheel brakes apply friction to the wheel (usually the idler wheels of cranes.) Thus, while wheel brakes are intended for static use, they can be used as dynamic brakes in emergencies.

Rail clamps come in two forms: clamps that grip onto the sides of the rail and press brakes that push down on the top. Clamp mechanisms usually include rollers that run along the tops of the rails. Retractable systems are available for high-speed cranes where rollers would add additional resistance.

Press brakes use the crane’s weight to lock it in position while clamps rely on spring force (which can exceed 1,000 kN.) Press brakes are used where the rail top is flush with the roadway and inaccessible to side clamps. They also do a better job of accommodating variation in rail height.

Brake Application and Release

Rail clamps, rail press brakes, and wheel brakes are all designed for fail-safe operation. Spring-loaded mechanisms force the clamps or friction material against the rail or wheel. Then, power is applied to pull the clamps off.

With clamps and press brakes, the release is almost always performed by hydraulics. (Some smaller units have electric release mechanisms.) Likewise, wheel brakes are predominantly electric release. However, hydraulic systems are more complex, requiring a pump or pumps plus reservoir, and should be inspected for leaks periodically.

When selecting or specifying storm and parking brakes, remember to consider how they are released in the event of a power failure. Again, the manufacturers or a knowledgeable distributor will be able to advise.

Partner With Specialists

As safety-critical components, it’s essential to use only the correct storm and parking brake systems and components for your application. Kor-Pak works with multiple manufacturers and can advise on the various types and styles. Replacement parts and servicing are also available. Contact us for more information.

AC vs. DC Motor: What’s the Difference Between Them?

Posted on by

Are you looking for a new motor for an application or piece of construction equipment? Before making any purchases, you must know whether you need to buy an AC motor or a DC motor.

Both types of motors have practical uses in many industries. However, they differ in cost, efficiency, reliability, and performance. By assessing your project requirements, you will know the best motor for you using this guide.

Keep reading to learn about the differences between an AC and a DC motor. 

AC Motor

AC means alternating current. An AC motor uses AC power which reverses the current direction, alternating between positive and negative. 

There are two major types of AC motors — synchronous and induction. 

The synchronous motor rotates at the same rate as the frequency of the supply current. 

The induction motor is the most common type of AC motor. The output rotation is proportional to the applied frequency of the alternate current. Electromagnetic induction creates the electric current that turns the rotor. 

AC motors are robust, durable, and affordable. In addition, they have a longer lifespan and lower repair costs than DC motors.

AC motors are used in large-scale, continuous-speed applications where the motor speed is slow to medium. This is because they are resistant and slow to respond to changes in speed when the load changes. 

AC motors are best for applications that need high speed and variable torque. They tend to lose torque at higher speeds.

DC Motor

On the other hand, a DC motor uses DC power. DC means direct current. The power flows in one direction, like in a battery. As a result, DC motors are usually more efficient than AC motors.

Additionally, they are also more expensive and have high repair costs.

There are also two major types of DC motors — brushed and brushless. 

Brushed motors use a carbon brush to conduct electricity through an internal commutator.

Brushless motors are similar to brushed motors, minus the brushes. Additionally, they have a specialized circuit to control power speed and direction. Furthermore, the motor uses magnets mounted around the rotor to improve efficiency. 

Brushed motors have a shorter life span than brushless motors because of the wear and tear of the brush. But, they have a more straightforward design, so they aren’t as expensive as a brushless motor.

DC motors are quick to respond to a change in the power load. Therefore, they are best for applications that need high torque and variable speed. 

Domestic applications and robotics most often use DC motors because they need fine speed control.

Brief Guide to Oil Rig Equipment

Posted on by

When it comes to operating factories, machines, vehicles, and even homes, the typical fuels used are gas and oil. In 2019, it was estimated that the world held 1,733.9 billion barrels of oil reserves, according to Discover Magazine. Finding this oil requires specialized equipment and exploration work to bring it up to the surface for processing. Oil rig equipment helps to extract the oil and petroleum from the land as well as from the sea.

Technology in the oil equipment industry has evolved for the exploration and drilling of oil to minimize damage to the ecosystem and prevent oil leaks that can harm the environment. From global positioning systems to remote sensing devices, these technologies are designed to help discover the possible location of oil reserves so that fewer exploratory wells are drilled. Check out our brief guide regarding some of the oil rig equipment used in this industry.

Mast

An essential structure on an oil rig is the mast. The mast, also called a derrick, holds and lifts the components used in the drilling operation. It acts as a lifting device for the drill string, such as the drill pipes and other accessories.

Drill String

The drill string refers to all the drill pipes, the bottom hole assembly, and all the other components used in the operation of the drill bit that will tun at the wellbore’s bottom. The drill string comprises the drill pipe, drill collars, drill jars, stabilizers, heavyweight drill pipe, and other tools.

Rotary Table

The rotary table is a section of the drill floor that rotates or spins. It provides power to the drill string and the bit as it moves in a clockwise rotation. The rotary table’s power is transmitted through the kelly bushing, as the entire rig is sometimes called a kelly drive rig. The rotary table may be used for primary power or backup power.

Top Drive

The top drive consists of a motor that is suspended at the top of the mast. The motor turns the drill string as an alternative to the rotary table and may be used in special circumstances. The top drive assists with the bore head drilling process.

Mud Pump

The mud pump is a reciprocating pump that circulates the drilling fluid (drilling mud) downhole along the drilling string and back up to the surface through the annulus, the space between the casing and wellbore or casing and tubing. This fluid circulation is at extremely high pressures.

Shale Shakers

Shale shakers are fluid separation systems that remove the large solids (cuttings) from the drilling fluid. Shale shakers help reduce drilling costs and make operations efficient while ensuring the drilling fluid circulates to keep the drill bit cool.

Many other oil rig technologies and equipment are used—ensuring that the equipment functions correctly and that replacement parts are available in case of breakage, allows an oil rig to function optimally when extracting petroleum and oil from the earth’s depths. Here at Kor-Pak, we offer oil rig equipment. Contact us for more information.

Torque Limiter Maintenance, Repair, and Replacement

Posted on by

Torque limiters are critical elements in rotational machine assemblies that protect against instantaneous overload conditions.

Overloads are often multivariable and caused by both mechanical and electrical factors. Therefore, a torque-limiting switch is implemented to mitigate potential overload damage, regardless of the root cause. Limiters establish a peak value for torque-generated force in a system.

Rotational components operate uninterrupted within the bounds of the set torque limit. When the limit is exceeded, the operating machine is immediately detached from the load. The load separation stops the overload cascade from surging through the system, avoiding potential damage to the machine and its operators.

Proper maintenance and repair scheduling of limiter components should be prioritized in any heavy-duty, high-cycle operation. Machine troubleshooting can be conducted after a power failure, but any resulting damage cannot be undone. Effective use of a torque limiter circumvents much of the risk inherent to equipment failures.

Torque limiters are mostly autonomous but are not immune to malfunction or regular wear and tear. Several operative signals may indicate your torque limiter needs repair or replacement.

1. Abnormal Sounds at Start-Up

A sudden separation from loading elements is not a gentle process. During successful operation, torque limiters generate noise – and this should be expected.

On occasion, a torque-based system may emit a grinding, slamming, screeching, or whirring noise on start-up. These sounds can be accompanied by non-typical rumbling or physical motion in the equipment (as if a component was being tossed around). However, if the system is operating beneath the torque threshold set by the limiter, there should be no rattling, slipping, or squealing from the protective component.

Assess the characteristics of the noise and when it occurs. For example, if there are consistent noises at start-up, the torque limiter may be improperly installed, damaged, or over-slipping.

2. Motor Will Not Turn-Over / Start

Depending on the equipment, the torque limiter may be implicated in no-start conditions.

For example, electric engines that demand maximal torque at start-up – zero revolutions – may trigger immediate slippage by the torque limiter. As a result, the motor will be unable to turn over. A no-start might be accompanied by the sounds noted above, ignition chugging, or another rattling in the equipment.

3. Torque Limiter Slippage

Torque limiters are designed to slip – that’s how they can disengage from the load component. However, a total slippage of the limiter can mean operators will be unable to start or re-engage the equipment. Thus, slippage is undesirable below the set torque threshold. Coincidentally, over-slippage tends to be responsible for many situations involving abnormal noises and no-start motor conditions.

The type of torque limiter affects the mode of slippage. For example, friction plate, magnetic particle, and magnetic hysteresis torque limiters use different slip mechanisms to achieve the same operational goal.

5 Reasons Why You Need an Overhead Crane Inspection

Posted on by

Overhead cranes allow companies to move materials from one location to another with the items suspended in the air. It is commonly used in warehousing and transportation, yet these cranes are also found in mining processing, agricultural manufacturing, and many other industries. Ensuring that your overhead crane functions optimally means that the working mechanisms and supports have undergone proper maintenance and repair. Overhead crane inspections are another essential aspect of properly maintaining your equipment. Find out why you should get your overhead crane inspected.

Reasons to Perform Overhead Crane Inspections

1. Spot Cracks, Deterioration, and Failures

Inspections allow you to spot potential problems before they become serious issues. Overhead cranes work with many moving parts at once. Any part that experiences failure could lead to the entire crane malfunctioning to the point where it can no longer perform tasks. Certain overhead crane features should undergo daily maintenance, such as the hydraulic systems and crane hooks. Other areas can have monthly inspections such as hoist chains, ropes, and end connections. Some inspections may be performed on an as-needed basis.

2. Avoid Costly Part Replacements

Spotting minor problems and immediately placing the overhead crane into service ensures that all components function appropriately. However, holding off on the inspections and required repairs could lead to catastrophic failure to the crane’s systems. When devastating failure occurs, it may lead to replacing entire systems. The cost of replacing systems can be an enormous burden on the company’s finances.

3. Helps to Create Preventive Maintenance Checklist

An inspection provides you with essential details about your overhead crane and how it is used. The inspector may notice specific components and parts that are worn out faster than the manufacturer’s recommendations during the inspection. With this data, you may adjust the preventive maintenance checklist to evaluate these systems and components on a more daily schedule to prevent significant problems.

4. Meet OSHA Requirements

Overhead crane and gantry operations are regulated by the Occupational Safety and Health Administration (OSHA). If the cranes are not inspected and maintained following these guidelines and standards, accidents may cause serious damage and worker injuries. OSHA regulators may penalize a company that has not performed the required inspections and instituted safety measures in compliance with stated guidelines. These fines could be costly for your company,

5. Prevent Worker Injuries

Having a worker become injured due to materials falling from the overhead crane causes significant problems to your company. You must ensure that the working environment is cordoned off to prevent further damage and injuries. Then you have to deal with the worker’s medical bills, worker compensation claims, or even lawsuits. Your operations will also have to remain down until the evaluation of the overhead crane is complete, and they determine why there was a failure. Then you must make repairs before operations begin again.

An overhead crane experiences large stress loads daily. Ensuring that the equipment functions efficiently is essential so that operations keep up with productivity. An overhead crane inspection provides many advantages to your company to keep equipment running and keep repair costs low.

EMG Thruster Maintenance and Repair

Posted on by

The high demand for EMG thruster units often results in low stock across distribution channels. Replacing an electrohydraulic thruster can impair project lead times significantly and introduce a significant cost burden. Adhering to a proper repair and maintenance protocol enables a quicker and more economical turnaround.

Design and Operation

ELDRO and ELHY electrohydraulic thrusters are built with scalable, long-term use in mind. Versatility in a wide range of environmental and project-specific scenarios is prioritized in the design.

Primary design features include:

  • Reliability and long service life
  • Minimized regulating periods – fast response
  • Multipurpose designs may be specified for the environment
  • Operational overload protection
  • Straightforward assembly, disassembly, and installation
  • Multidirectional motor rotation – removing the need for reversing contractor components
  • Switching frequency graded to 2000 cycles per hour
  • Adjustable stroke
  • Modifiable lift and lower times

EMG thrusters are commonly employed industrially in crane, mining, and conveyor machinery. Systems demanding high-duty cycles in harsh operative conditions can stand to benefit from an electrohydraulic thruster unit.

ELDRO

ELDRO thrusters are built according to a coaxial functional assembly comprised of an electric motor and hydraulic unit. Implicit to a hydraulic system, thrust is generated via an appropriate operating fluid modulated by a centrifugal pump. The piston is designed to retract automatically if operational power is lost, and the brake springs will lock into place.

ELHY

ELHY brake thrusters are compact, low-noise units provided in several models bearing the same general structure. A three-phase motor is housed at the base, attached to a terminal box. The hydraulic pump is seated atop the motor, which connects to the piston and rod shaft. The ELHY model is crafted to ensure last-line defense against power failures and operative malfunctions.

Risk Factors

Electrohydraulic thrusters are often subject to extreme conditions. The intentional balancing of a thruster’s internal components and casings requires special awareness on behalf of operator and machine wellbeing.

EMG units are equipped with positional measurement systems and internal level indicators. These mechanisms indicate stroke path, piston rod depth, and release or brake position. In addition, limit switches may be utilized to provide more sophisticated data. Careful monitoring of EMG measurements can give a predictable baseline and point toward equipment fitness.

Corrosion is an active risk for any mechanism operating in high relative humidity or conditions where excessive condensation builds. EMG thrusters are fitted with redundant seals and protective tubing, but increased protection is recommended for intensive circumstances. Operators may consider the use of parking heaters or specialized sealing paint for the housing structure.

Repair and Maintenance Protocol

Kor-Pak offers consultations for use and rapid turnover repair services of EMG thruster units.

Our standard repair process involves complete strip-down disassembly of the electrohydraulic unit. Kor-Pak conducts a thorough visual inspection of each component. Housing, motor, piston, and brake assemblies are evaluated for damage related to corrosion, impact, and excessive wear. Bearings, seals, gaskets, and paint are replaced as part of our service.

Each repaired unit is put through a load and environmental condition check, then certified by Kor-Pak’s specialists.
