Title:
BEARING OF COMPRESSOR FOR REFRIGERATOR
Document Type and Number:
Japanese Patent JPS59194128
Kind Code:
A
Abstract:
PURPOSE:To improve the reliability of a bearing by working the surface of the bearing in such a manner that both a composite material and a porous bronze- group alloy are previously exposed on the surface of the bearing. CONSTITUTION:On the surface of a bearing, a porous alloy 16 is exposed, so that even if a crankshaft 4 slides, a surface layer is not stripped, and a bearing clearance is not enlarged. As the surface of the bearing is formed of a composite material 17 composed of the porous alloy 16, plastic resin having a self-lubricating property and a lubricating material, even if oil supply temporarily goes wrong and the boundary lubricating state occurs, hesitation of slide due to seizure will hardly take place. A refrigerant is mixed in lubricating oil in an oil sump of a general compressor for a refrigerator. When such lubricating oil is supplied, the mixed refrigerant is caused to boil by sliding heat in the bearing, so that the boundary lubricating state is easy to happen at the bearing portion. Therefore, the operation can be conducted with high reliability by providing the above bearing.
