ABSTRACT:
A torque limiting mechanism provides for a spring loaded coupling of driver and driven friction discs for simultaneous and uniform rotation. A spring retainer system is incorporated which provides restraint against expansion of the spring beyond a predetermined limit. In a preferred embodiment the spring becomes inoperative to urge the discs together after friction linings on the discs have worn to a predetermined design limit. A condition of zero torque is thereby created, thus signalling need for replacement of friction linings.
