<p>A torque limiting overload device, or clutch, and suitable for use between a shaft, flange, or the dial for automated machinery, or indexing machine, a drive or rotating member imparting turning or rotational force to a driven or rotatable member, the rotatable member incorporates a series of detent seats in which ball detents held by the driving member are normally seated and effect a simultaneous rotation between these two members; a suspension plate holds the detent balls with respect to the driving member with both the suspension plate and the seat of the rotatable member being in contact with each detent ball on the same axially disposed side and therein prevent damage to the balls as they are unseated upon the couplings countering a predetermined excessive torque. A bearing is urged by means of a spring against a bearing race that places pressure upon the ball detents to maintain their seating within the detent seats, with adjustments to the spring providing for a variation in the amount of pressure exerted upon the detent balls and therefore the degree of torque necessary to effect a decoupling of its torque limiting assembly.</p> |
