Example Embodiment

[0028] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments:

[0029] The overall structure of the sealed rolling rotor compressor of the present invention is the same as that of the prior art. Still referring to FIG. 1, the present invention will be described.

[0030] The sealed rolling rotor compressor of the present invention includes: a housing 30, the inside of the housing 30 is a motor part 20 composed of a stator 21 and a rotor 22; the bottom of the compressor includes: a cylinder 35 with a compression chamber with a certain space inside; The rotor 22 is press-fitted into the fixed rotating shaft 31. There are upper bearing 32 and lower bearing 33 that can support the rotating shaft 31. The upper bearing 32 and the lower bearing 33 are fixed with fixed bearing screws 34. The upper part of the upper bearing 32 is provided with a lower row Air noise silencer 38; the inner surface of the rolling ring 36 is i...

Abstract

The invention discloses a bearing structure of sealed rotary compressor ,the said bearing comprises a upper bearings and a under one located in compressor and supporting rotor, a groove reducing inwall contact area of the compressor shell is installed on surface of outsede diameter of the upper bearing contacting inwall of compressor shell. The groove locates on the surface of outside diameter between top surface and bottom surface of upper bearing,which is a cirque groove paralleling the surface of upper bearing. Or the groove consists of two ralative position line shape groove be vertical the surface of upper bearing and many arc shape groove between two line shape groove. The invention wipes off some material on upper bearing in heating composing ways, which can avoid excess leash between shell and upper bearing and welded seam of shell, also improves the performance of compressor and reduces noise.

Description

technical field [0001] The invention relates to a compressor bearing, in particular to a bearing structure of a sealed rolling rotor compressor which reduces the contact area between the upper bearing and the compressor shell. Background technique [0002] Generally, a compressor is a machine that compresses a fluid. Its structure is composed of a closed container with a certain internal space, a motor part that generates a driving force inside the closed container, and a compression part that receives the driving force of the motor part and compresses the gas. [0003] Compressors are generally classified into rotary compressors, reciprocating compressors, scroll compressors, and the like depending on the shape of a compression section that compresses gas. [0004] As shown in Figure 1, the sealed rolling rotor compressor of the prior art includes: a casing 30, the motor part 20 composed of a stator 21 and a rotor 22 inside the casing 30; the bottom of the compressor includ...
