Freewheels are machine elements with particular characteristics:
- In one direction of rotation there is no contact between the inner and outer ring; the freewheel is in freewheeling operation.
- In the other direction of rotation there is contact between the inner and outer ring; in this direction it is possible to transmit high torque.
Are used as backstops, overrunning clutches and indexing freewheels. Freewheels can fulfil these functions completely automatically in the most diverse machines. No mechanical or hydraulic operating equipment is required, as for example with external actuated clutches or brakes.
With more than 50 years’ experience in the development, production and sales of freewheels, RINGSPANN offers the most comprehensive range of freewheels.
