Abstract
A clutch/brake assembly for selectively connecting a source of rotational power to a driven device includes an input hub and a flange secured to the input hub for rotation therewith. An output hub is journalled within the clutch/brake assembly for rotation relative to the input hub. One or more outwardly extending bosses are formed on the outer surface of the output hub. A friction plate is disposed about the input hub between the lower surface of the flange and the upper surface of the output hub. A ring of friction material is secured to the upper surface of the friction plate adjacent to the lower surface of the flange. The friction plate is connected to the output hub for rotation therewith and for axial movement relative thereto. To accomplish this, the peripheral edge of the friction plate has one or more axially extending finger portions formed integrally therewith. The finger portions have slots formed therethrough which are sized and positioned such that each of the bosses extends through one of the slots. After the output hub has been installed on the friction plate, the ends of the finger portions are bent radially inwardly to form retaining tabs which retain the output hub on the friction plate. The engagement of the bosses with the finger portions positively couples the friction plate with the output hub for rotation therewith as a unit, but permits the friction plate to move axially relative to the output hub during use. A coiled spring is disposed between the output hub and the friction plate, urging them apart from one another. The retaining tabs permit the output hub and the friction plate to be removed from the clutch/brake assembly to permit access to the interior thereof for service without requiring disassembly of the output hub from the friction plate.
