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
Shrink Discs are external clamping connections for the backlash free fastening of hollow shafts or hub to shafts. By tightening clamping screws conical surfaces are pulled together generating radial forces; these forces press the hollow shaft onto the shaft. Torques or axial forces can be transmitted frictionally from the hollow shaft to the shaft. Torques or axial forces can be transmitted frictionally from the hollow shaft to the shaft. The Shrink Disc itself is not involved in the transmission of torques or axial forces. The radial clamping forces which act through the circumference of the hollow shaft also ensure an optimum centring to the shaft.
Cone Clamping Elements
Cone Clamping Elements are internal clamping connections for backlash free fastening of hubs on shafts. By tightening clamping scres conical surfaces are pulled together generating radial forces; these forces create a frictional connection between the Cone Clamping Element and the shaft as well as the hub. Torques or axial forces can be transmitted from the shaft via the Cone Clamping Element to the hub.
Star Discs
Star Discs are flat-bevelled rings which are slotted on the outside and inside. An external axial actauting force is translated by the Star Disc into a much higher radial force. This force creates a frictional connection between the Star Disc and the shaft as well as the hub. Generally, Star Discs are installed in a multiple arrangement as a disc pack.This makes it possible to adjust the transmissible torque to the requirements of the specific applications.
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, backlash free torque transmission, these systems also ensure precise centring of the torque motor on the machine shaft.
Star Spring Washers as Ball Bearing Compensating Discs
RINGSPANN Star Spring Washers are particularly light spting elements with linear or non linear spring characteristics. They are suitable for application as pressure elements in precision machines and as pressure springs for taking up free movement, and for reducing noise in ball bearings.
