ABSTRACT:
This instrument can fulfil two purposes. It can be a torque limiter which transmits torque up to a limit set by design, without slip. At higher values of torque it behaves as an absorber of energy. It can be cyclic or unidirectional or impact in operation. It can be applied as an absorber of wind or earthquake forces, as a buffer or fender in a transport system, as a brake, or as a torque limiter in a shaft transmitting power. Its commonest form is an eccentric within a cylinder, the intervening space being filled with a material capable of spontaneous recovery and recrystallisation at the working temperature.
