Document Type and Number:
Japanese Patent JP6991077
Kind Code:
B2
Abstract:
To provide a rotary compressor and a refrigeration cycle device capable of forming a sufficient oil film between an eccentric portion and a roller.SOLUTION: A rotary compressor has a rotary shaft; a plurality of compression mechanism part; and a partition plate. The compression mechanism has a cylinder, an eccentric portion, and a roller. The cylinder forms a cylinder chamber. The eccentric portion is provided on the rotary shaft. The roller is fitted with the eccentric portion and can eccentrically rotate in the cylinder chamber. In at least one of the plurality of compression mechanism portions, the eccentric portion is formed by the eccentric member that is a separated body and has an insertion hole in which the rotary shaft is inserted. On an outer peripheral surface of the eccentric member, a recessed portion to which a lubricant is supplied is formed. On a bottom surface of the recessed portion, a through-hole connecting to the insertion hole is formed. The rotary compressor has a fixing tool inserted in the through- hole to fix the eccentric member and the rotary shaft.SELECTED DRAWING: Figure 1
