Ringspann Housing Freewheels
Housing Freewheels FH
for stationary arrangement
with hydrodynamic roller lift-off
- Overrunning Clutch
at high speeds, which are the same or similiar in freewheeling operation and in driving operation.
Housing Freewheels FH with hydrodynamic roller lift-off are typically used in cases where an assembly can be driven from two or more motors or turbines at the same or similar high speed. They allow a continuous plant operation in the event that one of the energy sources or a drive line fails as well as energy saving in the case of partial load operation.
The Housing Freewheels FH are completely enclosed freewheels for stationary arrangement with input and output shaft.
Housing Freewheel FCBM
Backstop for Kiln drives
with electromagnetic and manual release function
The Housing Freewheel FCBM is used to control reverse rotation of the kiln when a rotary kiln drive is shut down. It is equipped with a Cage Freewheel on the main shaft and a multi-disc brake as well as a centrifugal brake on the worm shaft.
When the rotary kiln drive is shut down, the Cage Freewheel automatically engages the main shaft and the worm shaft. The closed multi-disc brake prevents reverse rotation of the rotary kiln. Through electromagnetic or manual releasing of the multi-disc brake, the controlled reverse rotation of the rotary kiln is then initiated. During reverse rotation, the centrifugal brake is used to ensure a controlled low speed of the rotary kiln until it has come to a stand still.
The Housing Freewheels FCBM is a completely enclosed freewheel for stationary arrangement with input and output shaft. It was developed to protect people and machines from injury and damage.
