Abstract
A safety clutch transmits torque between two coaxial machine parts. The safety clutch includes a basic body for the at least indirect frictionally engaged connection of two machine parts, and at least one thin-walled sleeve which forms a wall of an annular chamber upon which pressure medium can act. At least one feed line extends through the basic clutch body to the annular chamber and can be closed in an air and fluid-tight manner by closure elements, in particular closure valves. A pressure-relief mechanism can act at least indirectly on the closure elements. The pressure-relief mechanism is coupled to an arrangement for detecting a disturbance variable. The clutch includes devices which activate the pressure-relief mechanism when the influencing quantity occurs.
