ABSTRACT:
An overload clutch for a torque transmission is disclosed which comprises a rotatable drive member coaxially coupled to a rotating driven member. One of the drive member and driven member, hereinafter referred to as the first member, comprises an annular band delimiting a central space, the annular band having a cylindrical inner face provided with at least one engaging element. The other one of the drive member and driven member, hereinafter referred to as the second member, is mounted within the central space and comprises a radially expandable mechanism provided with at least one coupling element. The radially expandable mechanism is movable between an expanded position, where the at least one coupling element is positively engaging the at least one engaging element to couple the first member to the second member for rotation together, and a retracted position, where the at least one coupling element is disengaged from the at least one engaging element, thereby releasing the first member from the second. A biasing means, preferably a pneumatic actuator, is provided for normally resiliently urging the expandable mechanism in the expanded position, and for allowing the same to move to the retracted position when a predetermined torque overload is applied to the torque transmission.
