    摘要： Provided is a scroll fluid machine that, by using a crankshaft manufactured by cold forging and a needle bearing, can sufficiently exhibit the performance of a variable circling radius mechanism, can provide a sufficient reliability on a bearing portion of the crankshaft, and can be manufactured inexpensively. For this purpose, in a crankshaft 60 used for a driving force transmission system, a reinforced shaft unit 63 and a circular column-like large diameter unit 61 are formed at an end of a rotating shaft 16, a material is produced by a cold forging process so that an eccentric shaft 62 projects from the circular column-like large diameter unit 61, the circular column-like large diameter unit 61 is rotatably coupled to a housing 11 via a needle bearing 64, and the variable circling radius mechanism is stably operated with rigidity increased by the reinforced shaft unit 63.

    摘要： There is provided a scroll compressor in which reliability and durability is increased by preventing peeling of a coating layer applied to a thrust plate, to maintain a desired level of lubrication for a long period of time. A scroll compressor 1 comprises a thrust plate 51, a coating which is applied to a surface of the thrust plate, a housing 3 having a thrust bearing face 5B to which the thrust plate 51 is attached, an orbiting scroll member 27 having a slide face 61 which is supported by the thrust plate 51 and which orbits while sliding, and a peeling prevention part which reduces a sliding pressure acting on an edge portion 51C of the thrust plate 51 from the slide face 61.

    摘要： A scroll compressor that suffers no decrease in compression performance due to leakage resulting from a twisting assembly error is provided. This scroll compressor includes a fixed scroll and an orbiting scroll, each including a spiral wrap protruding from an end plate and having the same tooth thickness (Tr) and the same base-circle radius (b) defining an involute surface. The fixed scroll and the orbiting scroll are offset from each other by an orbiting radius (ρ) and mesh such that the respective wraps face each other with a phase shift of 180°. The orbiting scroll revolves/orbits along a circular orbit with the orbiting radius (ρ) to compress a gas while a rotation-preventing mechanism prevents rotation of the orbiting scroll.
