Abstract

PURPOSE: To improve abrasion resistance in the sliding faces of a main and an auxiliary bearings by providing the main and auxiliary bearings with nitride layers in a compressor provided with the main and auxiliary bearings for airtightly closing the both side faces of a cylinder for accommodating an eccentrically rotated roller.
CONSTITUTION: When a shaft 2 is rotated by a motor, a roller 7 is rotated eccentrically inside a cylinder 4 so that refrigerant is sucked into a compression chamber partitioned by a main bearing 5 and an auxiliary bearing 6 for closing the cylinder 4 and both side faces of the cylinder 4 airtightly, and discharged after being pressurized. In this case, nitride layers 21 are formed, by nitriding, on the surface of the main and auxiliary bearings 5, 6. This results in improving abrasion resistance against the sliding friction of the roller 7.
