Abstract

PURPOSE:To provide a thrust bearing described in the title, having structure which is stable even when it is kept at high temp, and producing no camber even when outside force is applied, by constituting the thrust bearing of an inner and an outer ring made of steel material subjected to specific heat treatment. CONSTITUTION:The inner and the outer rings 15a, 15b for the bearing of the swash plate of a swash plate axial compressor is made of steel material subjected to specific heat treatment. That is, the inner and the outer rings 15a, 15b are made of steel material which is heated to a temp. not lower than the As transformation temp, quenched in water or in oil, and is tempered at 200-300 deg.C temp, which is higher than standard tempering temp. The inner and the outer rings 15a, 15b subjected to specific heat treatment described above have stable structure, being relieved of residual stress, and produces no deformation when it is used at high temp. of 160- 250 deg.C. In figure, 13 is a driving shaft, 14F, 14R are supporting portions of the cylinder, 15 is the thrust bearing, and 16 is the swash plate.
