Fluid machine

Abstract

Abstract PURPOSE:To simplify the supporting structure of a main whirl drive shaft in a fluid machine, by axially aligning the effective axial supporting point of an angular bearing for supporting the whirl drive main shaft, with the drive point of a whirl piston so that the above-mentioned bearing alone supports all radial load. CONSTITUTION:A main shaft 13 is supported at its disc rotor 131 part by an angular bearing 333 which is arranged so that the effective axial action point thereof is axially aligned with the drive point of a movable scroll member 26 and radial load due to drive force may be supported at one point. Thrust force generated by the above-mentioned bearing 333 is received by a disc 330 which is attached to the disc rotor 131, a needle bearing 33a and a thrust race 332. Accordingly, the main shaft 13 may be supported by only the above-mentioned bearing 333 so that the supporting structure of the main shaft may be simplified.
