Document Type and Number:
WIPO Patent Application WO/2012/020740
Kind Code:
A1
Abstract:
Provided is a refrigerant compressor capable of suppressing the occurrence of the galling and seizing of a bearing sliding part and capable of improving abrasion resistance. The refrigerant compressor is provided with a compression mechanism part for interlocking a fixed scroll (100) and a pivoting scroll (200) and for compressing refrigerant, and a rotary shaft (300) for driving the compressor mechanism part. At least either the engagement part for the rotary shaft and the compression mechanism part or a rotation support part for supporting the rotary shaft is provided with slide bearings (210, 401). The slide bearings are constituted from a lead-free resin impregnated material having a foreign substance embedding property for embedding abrasion particles. The rotary shaft is constituted from an iron-based material; a hard film (1000) having a hardness of 1000 Hv or greater is formed on the part of the rotary shaft that slides with the slide bearings.
