A means for attaching the bearing housing to an outer shell is disclosed. The outer shell is plastically deformed into a plurality of apertures formed into the bearing housing. The deformation of the shell is such that material is displaced into the aperture of the bearing housing member without penetrating through the wall of the shell, thus maintaining the integrity of the shell. The shape of the displaced material of the shell is such that a generally cylindrical load bearing surface having a sharp corner is created which is capable of withstanding both axially and circumferentially directed forces of substantial magnitude.

Compressor assembly with staked shell

A method of assembling a hermetic refrigeration motor compressor is disclosed wherein the motor stator is assembled in a first shell section, the compressor is assembled in another shell section and the two shell sections are aligned and secured together in such a manner as to insure a uniform air gap between the rotor and stator. The method employed enables the two shell sections to be initially locked in position before complete welding of the periphery so as to avoid potential heat distortion.
