Scroll compressor

Abstract

The invention relates to a scroll compressor, and belongs to the field of small refrigeration and air conditioners. The scroll compressor is composed of a motor part, a fixed disc part, a movable disc part, a main shaft part and the like, and the structural design of three anti-rotation small shafts matched with a movable scroll plate body and a fixed scroll plate body of traditional cylindrical scroll compression is changed into the structural design of four anti-rotation small shafts. The kinematic pair rigidity and the bearing capacity of a bearing are improved by increasing the diameters of the four anti-rotation small shafts on a movable scroll plate and increasing the size of the bearing when the movable scroll plate operates at a high speed, the movable scroll plate and a fixed disc are structurally designed to be square, and the four anti-rotation small shafts are installed at the four corners of the fixed disc to be connected with the movable scroll plate. The tail end of an involute scroll wrap of a movable disc of a traditional scroll compressor is innovatively designed into a non-involute wrap for ending. The service life of the compressor is prolonged, the reliability of the compressor is improved, the technical requirements of a novel fighter plane are met, and the working reliability of airborne electronic equipment of a fighter plane is better guaranteed.

Description

technical field [0001] The invention belongs to the field of small refrigeration and air conditioning, and in particular relates to a scroll compressor. Background technique [0002] A scroll compressor is a fluid machine that realizes gas compression by volume change, and is the core of an air-conditioning device. As the 4th generation compressor product, the scroll compressor has the characteristics of good sealing, high volumetric efficiency, small vibration, low noise, few parts of the whole machine, light weight, small size, stable operation, high performance, low power consumption, etc. With the application of modern high-precision CNC machine tools, scroll compressors will definitely be the leading products in the development of automotive air conditioners and new energy vehicles in the future, and will be more and more widely used in the field of small refrigeration and air conditioning and the field of environmental control of military aircraft.
