Design/Function
The Safeset consists of a twin-walled pressure sleeve. This can be pressured up to 1000 bar using oil under high pressure, while a shear tube ensures that the system is completely sealed.
A shear ring is fixed to the shaft. If any overload occurs, this shear ring breaks off the top of the shear tube.
The area around the pressure surface and bearing is filled with a special oil, which supports a constant friction coefficient and, in turn, gives a precise release torque.
In contrast to shear element couplings the release torque of the Safeset is not influenced by material fatigue, i.e. SN datas. The release torque always remains constant.
The Safeset can be returned into operation after a minimum of delay by replacing the shear tube and reapplying the pressure!
