Abstract
A multiple disc torque limiting clutch has an output hub in interference fit upon an output shaft. After being so assembled, as by a heat shrink fit, the output hub and shaft can be received by the remainder of the torque limiting clutch, consisting of interleaved friction discs and separator discs maintained between end plates. A pressure plate urges the friction discs and separator discs toward a fixed friction disc which is secured to the output hub. The force upon the pressure plate is attained by a Belleville spring and circumferentially spaced spring cup assemblies.
