BEARING FOR REFRIGERATING MACHINE COMPRESSOR AND COMPRESSOR

A porous bronze (1b) and a resin (1c) impregnated in pores of the porous bronze (1b) formed on a backing metal (1a) constitute a bearing (1). At a surface to be brought into contact with a crank shaft (5), porous bronze (1b) and resin (1c) are sparsely exposed. Ratio of area of exposure of porous br...

Beschreibung
Zusammenfassung:	A porous bronze (1b) and a resin (1c) impregnated in pores of the porous bronze (1b) formed on a backing metal (1a) constitute a bearing (1). At a surface to be brought into contact with a crank shaft (5), porous bronze (1b) and resin (1c) are sparsely exposed. Ratio of area of exposure of porous bronze (1b) at the contact surface (1d) is at least 5% and at most 60%. Thus a bearing for a refrigerating compressor having high seizure resistance at the time of boundary lubrication and having small amount of wear caused by sliding can obtained, and the refrigerant compressed by the refrigerating compressor is a hydrofluorocarbon based substitute refrigerant not including chlorine.
