Description of the Related Art German Patent Publication No. 1965275 describes an overload clutch which transmits a progressively increasing limited range of rotational moment between a driving part and a driven part arranged coaxially with this driving part. Have been. Conventional overload clutches are provided with spring-loaded locking elements in the form of balls equally spaced from one another and insert these balls into corresponding rest pockets of the drive part. Beyond the critical turning moment, these balls exit the rest pocket and allow the driven part to rotate circumferentially with respect to the driving part. However, as the overload clutch is used for a longer period of time due to point contact of the ball located against the opposing surface of the rest pocket, it gradually becomes buried in the corresponding opposing surface of the rest surface. This results in progressively greater effective dissociation angles and progressively greater rotational moments for disengaging the ball from the dormant pocket.
