Abstract

PURPOSE: To prevent the generation of a seizure, a gall, and the like, by forming a main bearing near a compression chamber, and a sub-bearing to hold an electromotor at the opposite side, by providing sliding bearings at the inner surfaces and spherical bearings at the outer surfaces respectively.
CONSTITUTION: In the compressor main body 1, a rotary shaft 4 is inserted to the inner bore of a spherical bearing A3 preset to a frame 2 as a main bearing. And the eccentric part at the upper part of the rotary shaft 4 and the inner bore of a rotary scroll 6 are fixed between the frame 2 and the rotary scroll 6 through an Oldham's ring 5. Furthermore, at the lower part of the rotary shaft 4 of the compressor main body 1, the inner bore of a sub-bearing 13 to which a spherical bearing B is installed is connected integrally. And the main bearing and the sub-bearing 3 and 13 are set in a sliding bearing structure in the inner surface, and in a spherical bearing structure in the outer surface, respectively.
