Voith Safeset is a torque limiting safety coupling for release torques from 500 to 10,000,000 Nm. With shapes and sizes and shaft diameters from 30 to 1,000 mm it is excellently suited for any type of system.
The Safeset safety coupling is comprised of a twin-walled pressure sleeve that is inflated at an oil pressure of up to approx. 1,000 bar and is released absolutely tightly by several shear-off tubes.
A shear ring cuts off the shear tube and thereby protects the system from overload; bearings prevent the contact of friction surfaces. A special oil used in the pressure surface and bearing areas guarantees a constant coefficient of friction and thereby high release accuracy.
As opposed to break-off element couplings, the release torque is not influenced by material fatigue.
