Compressor anti-rotation mechanism

Abstract

The invention discloses a compressor anti-rotation mechanism. The compressor anti-rotation mechanism includes a bracket, a static vortex disk and a dynamic vortex disk. The periphery of the dynamic vortex disk is provided with at least three dynamic vortex disk cylinder pins. The dynamic vortex disk cylinder pins are arranged on one side of a dynamic vortex disk vortex body. The periphery of the static vortex disk is provided with at least three static vortex disk cylinder pins. The static vortex disk cylinder pins are arranged on one side of a static vortex disk vortex body. The dynamic vortex disk cylinder pins are matched with the static vortex disk cylinder pins in a one-to-one mode. The dynamic vortex disk cylinder pins and the static vortex disk cylinder pins which are matched with one another are detachably provided with anti-rotation circles which limiting the rotation of the dynamic vortex disk in a sleeved mode. The compressor anti-rotation mechanism concentrates the advantages of anti-rotation of the cylindrical pins and balls, the efficiency of a compressor is improved advantageously, meanwhile, the machining difficulty is reduced, the compressor anti-rotation mechanismis easily achieved in the project, and the machining cost is reduced.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor anti-rotation mechanism. Background technique [0002] A scroll compressor is usually composed of a moving scroll, a fixed scroll, an anti-rotation mechanism, an eccentric shaft, and a bracket. During the working process, the eccentric shaft drives the movable scroll, and the scroll body of the movable scroll meshes with the scroll body of the fixed scroll to gradually compress the gas. During the compression process, the movable scroll must be prevented from rotating to ensure the correct engagement of the movable scroll and the fixed scroll. Commonly used anti-rotation mechanism cross slip rings (also known as cross couplings), cylindrical pins, special mechanism ball bearings, small crank shafts, etc. [0003] There are two types of existing cylindrical pin anti-rotation mechanisms: (1) The cylindrical pin is fixed on the moving disk, and there is a hole in ...

AI Technical Summary

Problems solved by technology

There is sliding friction between the cylindrical pin and the anti-rotation hole or the metal ring in the anti-rotation hole, and the friction loss is large, which affects the working efficiency

In addition, for the cylindrical pin anti-rotation mechanism, the bonding surface of the bracket and the moving plate is sliding friction during the working process, and the friction loss is large, which affects the working efficiency

[0006] For the ball bearing anti-rotation mechanism of special mechanism, in order to ensure that the balls can work normally, the ball socket on the annular fixed ring needs high dimensional accuracy and position accuracy, resulting in very high cost of the annular fixed ring, and it is very easy to cause the entire machine to be damaged due to precision problems. compressor damage

The annular fixed ring must bear the anti-rotation force. In order to prevent the annular fixed ring from wearing out, heat treatment and other processes are required, which further increases the difficulty and cost of manufacturing.
