Problems solved by technology

[0004] However, with this kind of design, during the working process of the compressor, the high-pressure and high-speed refrigerant cycle will impact the lower end surface of the rotor, causing the rotor and the crankshaft to jump up and down, and the lower end surface of the eccentric part of the crankshaft will hit the upper end surface of the lower bearing. As a result, the lower end surface of the eccentric part of the crankshaft is severely worn, the noise is abnormal, and the power consumption of the compressor is also increased.
[0005] Therefore, how to solve the problems in the prior art that the lower end surface of the eccentric part of the compressor is seriously worn, prone to noise and high power consumption of the compressor has become an important technical problem to be solved by those skilled in the art

Abstract

The invention discloses a rotary compressor. The rotary compressor comprises a shell with a lower cover, an air cylinder arranged inside the shell and a crankshaft with an eccentric part, wherein the eccentric part is supported in the air cylinder through a bearing set, and an axial supporting component is arranged on the inner side wall of the lower cover and makes contact with the lower end face of the crankshaft to axially support the crankshaft. According to the rotary compressor, the problem that the lower end face of the eccentric part is seriously worn can be effectively avoided, the noise is low and the power consumption of the compressor is low.

Description

technical field [0001] The present invention relates to the technical field of compressors, more specifically, to a rotary compressor. Background technique [0002] During the working process of the rotary compressor, the motor rotor drives the crankshaft to perform high-speed rotary motion, and the eccentric part of the crankshaft rotates at high speed in the cylinder to realize the compression function. In the prior art, the upper part of the eccentric part of the crankshaft is provided with an upper bearing, and the lower part is provided with a lower bearing, and the eccentric part of the crankshaft is supported in the cylinder through the upper bearing and the lower bearing, wherein the upper bearing is arranged at the upper end of the cylinder, and the lower bearing is arranged at the cylinder the lower end. [0003] The inner rings of the upper bearing and the lower bearing have a radial restraint effect on the crankshaft, and at the same time, the upper end of the l...
