ENCLOSED COMPRESSOR CAPABLE OF ATTENUATING FRICTION NOISE GENERATING BETWEEN A CRANK SHAFT AND A BEARING AND A REFRIGERATING MACHINE INCLUDING THE SAME

摘要

PURPOSE: An enclosed compressor and a refrigerating machine including the same are provided to reduce frictional noise between each bush by making the bush with an aluminum material with a low frictional coefficient.;CONSTITUTION: An enclosed compressor comprises a casing(10) which includes a sealed indoor volume, a drive motor(40) which is installed in the inner space of the casing and wherein at least a part of the coil of the drive motor is composed of an aluminum coil, a crank shaft(43) which transfers torque to a compression part by being coupled to the rotor of the drive motor, and a bearing which rotatably supports the crank shaft. One side forming a bearing surface with the crank shaft is composed of an aluminum material.;COPYRIGHT KIPO 2010
