A REFRIGERANT COMPRESSOR AN AIR CONDITIONER AND A FREEZER EMPLOYING THE REFRIGERANT COMPRESSOR AND MEMBERS THEREOF

摘要

PURPOSE: A refrigerant compressor and an air conditioner and a refrigerator using the members are provided to secure a refrigerant compressor with long life, using a bearing material having high abrasion resistance and seizure-resistance, and secure an air conditioner and a refrigerator using the same and the bearing of the refrigerant compressor. CONSTITUTION: In a compressor, compressing a refrigerant by a pump driven by a crank(7a) of a rotating shaft(7), and repeating the liquefaction and evaporation for refrigerating, among an air conditioner and a refrigerator using the same, and the bearing, at least one of bearings to support the rotating shaft and the crank is made of a material prepared by impregnating pores of a carbonaceous base including graphite of 20-50 wt.%, with one kind of metal selected from the IB, VIII excluding Fe, and Sn, or an alloy mainly composed of the metal. The carbonaceous base includes graphite of 20-50 wt.%. Shore hardness of the member is 65-120 and a porosity of the member is 0.05-2 vol.%, and the metal or the alloy of the member includes at least one of V and Ti by 2.0 wt.% or less.
