Freewheels
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.
For example the outer ring of the freewheel shown in figure 4-1 can freewheel clockwise while the inner ring is stationary. If, however, the outer ring is turned in the opposite direction, there is contact between the inner and outer ring and the inner ring is driven (driving operation).
Freewheels are used as:
• Backstops
• Overrunning Clutches
• Indexing Freewheels
Shaft-Hub-Connections
Frictional shaft-hub-connections are standard machine elements used to connect shafts and hubs. They are capable of transmitting torque, axial forces, radial forces and bending moments. For example:
Shrink Discs and Cone Clamping Elements
Universal Cardan Shaft
For over 60 years, RINGSPANN Kempf GmbH in Gersfeld (Rhön) has led the way in cardan shaft design and production. We handle torques from 15,500 Nm to 284,000 Nm with unmatched quality. Our tradition drives us to modernize continuously and innovate.
