ABSTRACT:
A pneumatic air clutch assembly comprises: a hub having a flange and a cylindrical wall, a plurality of longitudinally extending teeth which project outwardly from the cylindrical wall, a longitudinally extending passage in the hub for receiving a shaft, and a plurality of driver plates slideably disposed on the teeth and biased in a spaced relationship. A driving ring includes a second plurality of teeth on which a plurality of spaced circular friction plates are slideably disposed and positioned between the driver plates. A holding plate is superposed over the driver plates at the distal end of the hub to capture the driver plates and friction plates and secured to the hub by fasteners. A pressure plate is interposed between the holding plate and the driver plates, and an inflatable tube is interposed between the pressure plate and the holding plate for selectively applying pressure to the driver plates. To ease assembly of the clutch, selected teeth on hub extend substantially over an uncompressed length X to the extent that the outermost driver plate is provided with minimum sufficient contact to align the plate on the teeth before the holding plate is secured to the hub. Uncompressed length X is defined as the distance from an inner surface of the flange to an inner surface of the outermost driver plate before the driver plates are compressed.
