Freewheels and One Way Clutches
How they work
Freewheels, sprags, one way clutches, backstops, overrun clutches, whatever you call them they function in one of three ways:- to stop a shaft running in reverse, to allow a shaft to run faster, or to index a shaft.
The Combidrive team have worked with STIEBER companies since 1968. Freewheels from Stieber, GMN, Formsprag, Tsubaki and Ringspann may be employed as: Overrunning clutches, Indexing Clutches or Backstops.
Some of the more common applications include:
- Packaging machines
- Conveyors
- Two speed drives
- Press feeds
- Exercise machines
- Turnstiles
- Automatic transmissions
- Agricultural machinery
- Hybrid vehicles
Geared Motor
Freewheel prevents run back through wrong connection of motor.
Inclined Conveyor
Freewheels prevents run back through power / transmission failure.
Packaging Machine
Freewheel holds flap in position caused by obstruction. Must be reset though 360 degrees by operator after obstruction is cleared.
Standby Drive
Electrical power failure allows petrol engine to drive without being driven over when electric motor is normally driving.
