Abstract

A torque limiting coupling has a first coupling hub (2) with first driving members (10), and a second coupling hub (27) with second driving members (35). The hubs (2, 27) are jointly received in a coupling sleeve (46) and are rotatable independently of one another. When a set torque is exceeded while the first coupling hub (2) is driven in one of two driving directions of rotation N1 or N2, the second coupling hub (27) is subjected to a force which ensures that, in the driving direction of rotation N1, the driving members (10) of the first coupling hub (2) are transferred into the disconnected position and that, in the driving direction of rotation N2, the second driving members (35) of the second coupling hub (27) are transferred into the disconnected position.
