CA 2148182
A rotary apparatus, such as a pneumatic motor, is disclosed. The rotary apparatus comprises an end plate having a race cavity, a main rotor with a stub shaft extending from one end, and a bearing, which includes an outer race seated in the race cavity and an inner race having a central bore. The stub shaft is fitted into the central bore with a frictional fit. In a preferred embodiment, the threaded shank of a screw is threaded into a threaded socket in the stub shaft so as to draw the stub shaft into the central bore with a washer bearing against the screw head, against the stub shaft, and against the inner race, whereby a controlled gap is provided between an outer surface of the main rotor and an inner surface of the end plate. In an alternative embodiment, a threaded nut is threaded onto a threaded stud extending from the stub shaft so as to draw the stub shaft into the central bore with a washer bearing against the threaded nut, against the stub shaft, and against the inner race, whereby the controlled gap is provided. Also, a related method for assembling the rotary apparatus is disclosed, in a preferred mode for assembling the preferred embodiment and in an alternative mode for assembling the alternative embodiment.
