Abstract

PURPOSE:To improve the durability in a bearing by supporting axial force to be produced in a scroll lap with a thrust bearing installed in the back of an end plate of a turning scroll, and making vertical movements of a drive shaft so as to be restricted by two separate thrust bearings. CONSTITUTION:An scroll compressor is made up of housing a scroll compressor part 2 consisting of a fixed scroll 6 and a turning scroll 7 provided with spiral scroll laps 6b, 7b at respective end plates 6a, 7a, and a motor part 3 rotating and driving the turning scroll 7 via a drive shaft 4 both in a hermetically sealed vessel 1. In this case, this drive shaft should be such one that formed a stepped part 4d with a large diametral part 4b with an eccentric hole 4a and a small diametral part 4c. And, both first and second thrust bearings 14, 15 are installed each between a side end face of the turning scroll 7 of this large diametral part 4b and the back of the end plate 7 as well as between this end plate 7b back and a frame 9. In addition, a third thrust bearing 16 is installed between the stepped part 4d of the drive shaft 4 and this frame 9.
