Abstract
A scroll compressor is assembled by force-fitting the pump unit and the lower bearing into the generally cylindrical outer housing. The force-fit holding strength is increased by providing both the crankcase and the bearing support with cylindrical portions. Thus, force-fit holding strength is provided over the entire periphery of the elements. The structure preferably takes the outer housing beyond its plastic yield point, also increasing the hold strength. In this way, the relatively simple method of force-fitting may be utilized to assemble the scroll compressor, while still achieving acceptable holding force.
