Description

The main function of a shrink disk is the safe connection of a shaft to a hub by means of frictional locking. For example between a drive shaft and a hollow gear shaft. The shrink disc creates a backlash-free connection by pressing the hub onto the shaft. This type of connection is mainly used for torque transmission. The shrink disc only provides the required forces and does not itself transmit any forces or torques between shaft and hub. It is therefore not in the force flow. Assembly is carried out by pushing the shrink disc onto the hollow shaft and then clamping it by the hydraulic system. By using conical surfaces, the inner diameter is reduced and the radial pressure is built up. After clamping is complete, the SHS is mechanically blocked and the hydraulic pressure is released. Due to this simple procedure, the SHS is suitable for repetitive clamping processes such as those that occur on a test stand. For proper function and to achieve a sufficiently high coefficient of friction, the contact surfaces between shaft and hub must be free of grease, dry and clean . The functional surfaces of the shrink disc are already lubricated ex works. The contact surfaces between the shrink disc and hub must also be lubricated before assembly.
