転軸構造。[Claims for Utility Model Registration] 1. A rotary compressor whose one end is connected to a rotor of an electric part, the other end is supported by a bearing part, and is connected to a roller of a compression part via an eccentric crank. In the rotating shaft structure, the rotating shaft main body is molded from a steel pipe, and the parts that come into sliding contact with the eccentric crank and the bearing are integrally formed by casting an aluminum alloy around the outer periphery of the steel pipe main body. The rotary shaft structure of the rotary compressor is characterized by: 2 The above aluminum alloy contains SiC, Si 3 N 4 , Al 2 O 3 at a volume ratio of 5 to 20% in an Al-Si alloy.
reinforcing agents such as BN, C, Mo at a volume ratio of 1 to 10%
The rotary shaft structure of a rotary compressor according to claim 1, which is made of a composite material in which a lubricant such as S 2 or WS 2 is dispersed.
