Abstract
To provide a compact clutch, two clutch parts (1, 2; 44,54,55,73,74) are located in axially fixed position on respective driving and driven shafts. The clutch can be automatically disengaged upon transfer of excessive torque, by including bolt elements (16,61) which are positioned circumferentially around one of the clutch elements (2) and parallel to the axis of rotation (17,60) of the clutch, the bolt elements carrying directly, or engaging respectively tooth or tooth gap elements which are shiftable axially against a bias force, for example provided by a spring (22). The tooth or tooth gap elements are rotatable about the longitudinal bolt axis by a limited angle, which angle is slightly above a relative angle of rotation of the clutch parts upon disengagement due to overload, so that the respective flanks of the tooth elements, engaged with tooth gap elements--or tooth gaps formed in the other clutch part--will remain in continuous engagement just until disengagement of the clutch to thereby provide extensive surface engagement contact between the respective clutch parts.
