Discharge manifold and mounting system for, and method of assembling, a hermetic compressor

Abstract

A compressor assembly includes a housing and a compressor mechanism is disposed therein which is partially supported by a manifold. The manifold extends across the interior of the housing, has an aperture therethrough, and subdivides the interior of the housing into a first discharge chamber and a second discharge chamber. An electric motor is disposed in the second discharge chamber and includes a stator and a rotor. A shaft operatively couples the compressor mechanism with the rotor. The manifold includes an aperture into which is received a discharge gas into the first discharge chamber and a plurality of chutes to direct the discharge gas into the second discharge chamber. The chutes are in fluid communication with an exterior of the compressor mechanism defining passages therebetween. The housing includes a main section and an end section which respectively include edges. A bearing support member extends across an interior of the housing and is supported between the edges of the main and end sections of the housing. The bearing support member has portions which project radially outward. An auxiliary bearing is supported by the bearing support member and the auxiliary bearing rotatably supports the shaft. A method of assembly includes: attaching the compressor mechanism to the manifold and welding the manifold to the housing; attaching the stator to the housing and the auxiliary bearing to the bearing support member; aligning the main bearing with the stator and welding the bearing support member to the housing.
