ABSTRACT:
A method is disclosed for converting a mechanically-actuated drive unit to an air-actuated drive unit (18) in an industrial power transmission system of the type having a short-shaft motorized input drive employing an input shaft (16) releasably connected to an output shaft (20) by the drive unit. A spider (14, 42) having a hub (50) is affixed to the input shaft. The drive unit has an input member (86) connected to a radial flange (68) of the spider and an output member (92) connected to the output shaft. The drive unit includes an actuator member (88) for releasing and connecting the input and output members. In the method, the mechanically-actuated drive unit is replaced with the air-actuated drive unit. A diameter of the spider hub is reduced and a rotary air seal adaptor (12) is affixed directly onto the reduced diameter spider hub. The rotary air seal adaptor has a stationary air chamber member (28) for receiving air from an external air supply source and an air chamber passageway (28a) for carrying said air.
