Abstract
A hermetic compressor assembly is disclosed including a compressor mechanism and an electric drive motor within a hermetically sealed housing. The electric motor includes a rotatable rotor and a stator. In one disclosed embodiment, the stator is friction fit within the housing and a rotor is press fit over a crankshaft journalled in a crankcase of the compressor mechanism. The crankcase is selectively positioned within the housing and mounted thereto by means of mounting pins. In another disclosed embodiment, the motor is mounted to the compressor mechanism and the compressor crankcase is axially supported in the housing. A mounting pin is used to prevent rotation of the compressor mechanism within the housing caused by torque forces produced by dynamic operation of the motor. The disclosed mounting pins are received within holes in the crankcase and extend radially outwardly through oversized apertures in the housing. The pins are selectively positioned in the apertures prior to welding. A method of assembling a compressor having mounting pins is also disclosed.
