ABSTRACT:
A torque release coupling in which a coupling hub is connected to the shaft of a prime mover for rotation. The coupling hub acts as a driving member for a rotary member which comprises a coupling housing, in turn secured to a driven apparatus. The coupling housing is provided with a plurality of radial pistons and is provided with notch means therein for receiving a plurality of axial piston means with the piston means being provided with biasing means to urge the axial piston means into the notched means of the radial piston means. The coupling hub is provided with a cam means having cam pockets therein for receiving the inner end of the radial piston means. The radial piston means can be provided with weight means which cooperate with the axial piston means to provide a centrifugaly assisted torque disconnect coupling. The cam pocket means can have a ratchet configuration so that the disconnect coupling can operate in a unirotational direction and when rotated in the opposite or counterclockwise direction can reseat themselves in the cam pocket means without requiring manual resetting thereof.
