Ringspann shrink discs and cone clamping elements

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

Shrink discs and cone clamping elements

Among the frictional shaft-hub-connections Shrink Discs and Cone Clamping Elements take an important position. By tightening clamping screws conical surfaces are pulled together generating radial forces; these forces provide the required frictional connection between the parts involved in the transmission of torques or forces.

Shrink Discs and Cone Clamping Elements are capable of transmitting much higher torques than conventional positive connections with keyways. The shafts can be designed smaller and shorter. The Cone Clamping Element design offers a much more compact and cost effective solution.

Star discs

A special category of frictional shaft-hub-connection is the RINGSPANN Star Disc. Connections using Star Discs are ideally suited to applications requiring repeated adjustment with adjustment devices in a short overall length.

Clamping systems for torque motors

Both complete torque motors and integrated torque motors can be connected by friction to machine shafts with RINGSPANN torque motor clamping systems. In addition to secure, back-lash free torque transmission, these systems also ensure precise centering of the torque motor on the machine shaft.
