Abstract
A torque limiting clutch for use with a hollow shafted motor has an input hub in operative connection with the hollow input shaft. A back plate is disposed at a fixed distance from the input hub. A plurality of interleaved friction disks and separator plates are interposed between the input hub and the back plate. A pressure plate is interposed between the input hub and the interleaved friction disks and separator plates. Spring cup assemblies are operatively interposed between the input hub and the pressure plate, urging the pressure plate toward the back plate and urging the friction disks and separator plates into frictional engagement. An output hub is connected to the friction disks and supported by a bearing from the back plate. An output shaft is connected to the output hub and extends through at least part of the hollow input shaft.
