Abstract
A torque-limiting tool which comprises a drive member and a driven member. A plurality of balls extends from one of the members; a corresponding plurality of cylinders extends from the other. The relationship of the drive member and the driven member is such that when a torque is applied to the drive member, the balls and the cylinders engage and drive the driven member until a predetermined torque is applied. Once this torque is attained, the balls and cylinders mutually rotate so as to release the driven member. A calibration screw adjusts the overlap between the balls and cylinders to calibrate the limiting torque.
