Problems solved by technology

[0005] However, during the working process of the scroll compressor, the above-mentioned Oldham coupling will be subjected to the action of torsional moment because the keys are arranged in a cross distribution, and then the Oldham coupling will be torsionally deformed and easily damaged.
The above-mentioned torsional deformation changes the contact area of ​​the key with the friction surface between the orbiting scroll and the support plate, resulting in a large friction loss

Abstract

The invention discloses a bracket for a scroll compressor. The bracket comprises a bracket disk and a rolling friction piece, wherein the bracket disk is fixed on a bracket disk retaining piece of the scroll compressor; and the rolling friction piece is arranged between the bracket disk and a movable scroll disk of the scroll compressor to supply rolling friction between the bracket disk and the movable scroll disk. Furthermore, the invention also discloses the scroll compressor using the bracket.

Description

technical field [0001] The invention relates to a scroll compressor in the field of air conditioning and refrigeration, in particular to a bracket in the scroll compressor. Background technique [0002] Generally, a compressor is a potential for converting mechanical energy into a compressible fluid, and can be specifically divided into reciprocating compressors, scroll compressors (or scroll compressors), centrifugal compressors, and vane compressors. [0003] Typically, the working principle of a scroll compressor is that the movable scroll rotates around the center of the base circle of the fixed scroll, and gradually reduces the volume of the gas compression chamber formed by the engagement of the movable scroll and the fixed scroll , so as to achieve the purpose of compressing gas. Wherein the orbiting scroll is directly supported to a bracket fixed in the scroll compressor housing. In addition, one end (upper end) of the crankshaft used to drive the movable scroll is...
