ABSTRACT:
The crankcase or cylinder body of a rotary compressor is secured in a shell by a shrink fit thereby providing intimate contact over its entire circumference. To maintain the proper positioning of the crankcase during the shrink fitting process, the outer surface of the crankcase defines a portion of a sphere, specifically the equatorial portion. As a result the spherical surface provides a stable contact surface over a range of positions of the crankcase and the intimate contact changes the frequencies of response of the shell.
