Abstract:
A compact disc spring torque limiting clutch has an input hub and an output hub having a friction pack that is removable from the input hub as an entire unit to facilitate servicing and repair. The force actuator of the torque limiting clutch is a Belleville spring or machined disc spring that is operatively interposed between the input hub and the friction pack. The deflection of the Belleville spring during the useful life of the friction pack is within the flat portion of the force vs. deflection curve and establishes a characteristic breakaway torque for the torque limiting clutch. The use of a Belleville spring significantly reduces the axial dimension of the torque limiting clutch, adapting it for use in applications where space is at a premium.
