Abstract
Torque limiting clutch comprising a driving member and driven member bearing mounted together, with the driving member having a flange integrally extending from its one end, and having locating slots therein, for accommodating a series of ball detents, and with a spring and adjustable nut biasing against the detents for forcing them into a seating relationship upon bearing seats provided upon a rotatable member formed integrally of the driven member; a structured support connects with the rotatable member and extends concentrically along the length of the driving member, and provides support for the adjustable screws and springs mounted therein, with the structured support further furnishing enclosure for these operating components of the clutch for assuring their freedom from contamination during routine clutch usage and operation. Various races are biased against the ball detents and assure the distribution of uniform pressure against the dentents in their adjustable relationship with the rotatable member of the driving member, and provide freedom for shifting of the detents as they are unseated during clutch disconnection. Various rods and a displacement plate are connected to the races and are shiftable during clutch disconnection so that a micro or other switch can be actuated for shutting off the operations of the connected machinery when excessive torque has been encountered and clutch disconnection occurs.
