Problems solved by technology

In related technologies, the flexible groove structure of the upper bearing and the lower bearing can improve the bearing surface pressure and the minimum oil film thickness, but under conditions such as liquid shock or maximum load, the surface of the bearing hole corresponding to the bottom of the flexible groove will still appear polished. Reduced operational reliability

Abstract

The bearing is arranged at the axial end of an air cylinder, the bearing is provided with a shaft hole used for inserting a crankshaft, the end face, facing the air cylinder, of the bearing is provided with a flexible groove, and the flexible groove is formed around the shaft hole. An annular groove wall is formed between the flexible groove and the shaft hole; in the axial direction of the bearing, the side wall, close to the shaft hole, in the flexible groove is obliquely arranged, so that the thickness of the groove wall in the radial direction of the bearing is gradually increased from the opening of the flexible groove to the bottom of the flexible groove, and compared with a groove wall structure with the thickness evenly distributed, the surface pressure of the bearing can be effectively reduced; and particularly aiming at severe working conditions such as liquid impact or maximum load, the phenomenon that the bearing is locally polished is effectively reduced, and the operation reliability of the compressor is favorably improved.

Description

technical field [0001] The invention relates to the technical field related to compressors, in particular to a compressor bearing, a compressor and refrigeration equipment. Background technique [0002] The upper bearing and the lower bearing of the rotary compressor are the pressure-bearing parts of the crankshaft. The surface pressure they bear directly affects the performance of the oil film and the anti-wear ability of the crankshaft. In related technologies, the flexible groove structure of the upper bearing and the lower bearing can improve the bearing surface pressure and the minimum oil film thickness, but under the working conditions such as liquid shock or maximum load, the surface of the bearing hole corresponding to the bottom of the flexible groove will still appear polished. Reduced operational reliability. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the ...
