Abstract
An overload coupling for two members, one rotating the other about a common axis, includes one or more frangible pin-like elements. Upon overload, the pin fractures and relative rotation between the members takes place. A spring or springs automatically urges one of the elements, mounted on one of the members, into engagement with an abutment on the other member to re-establish a rigid connection. The pin or pins can be in holders that extend radially or parallel to the common axis and each pin can be weakened in several areas and re-used. Also, a number of pins can be housed in a cassette that is connected to one coupling member by a release connection. Upon overload, in one embodiment, the spring or springs are mounted to urge the pin or pins only upon a reduction in the rotational speed of the coupling, when centrifugal force is overcome. The fragment broken off by the abutments in a channel for ejecting the fragment so that another pin or, at least an unbroken portion of the same pin, can re-establish connection as before.
