Novel swash plate type automobile air-conditioning compressor

Abstract

The invention discloses a novel swash plate type automobile air-conditioning compressor and belongs to the technical field of manufacture of compressors. The novel swash plate type automobile air-conditioning compressor comprises a compressor cylinder block, wherein one end of the compressor cylinder block is connected with a compressor spindle through a bearing pedestal; one end of the compressorspindle is positioned outside the compressor cylinder block and is connected with a belt pulley; the other end of the compressor spindle stretches into the compressor cylinder block and is connectedwith an integrated type swash plate; the integrated type swash plate comprises a pressure plate and an oblique bearing mounted in the pressure plate; placing grooves for mounting piston bodies are uniformly distributed in the pressure plate in the circumferential direction; one side of the oblique bearing is connected with the compressor spindle for driving the oblique bearing to rotate; and the other side of the oblique bearing is in rolling connection with the spherical surface of a spherical surface shaft in the compressor cylinder block. According to the novel swash plate type automobile air-conditioning compressor, the pressure plate and the oblique bearing are designed into an integrated structure, the overall structure is more compact after optimization, the optimized oblique bearing applies stress to the pressure plate through a ball, and the pressure plate generates rolling friction to the oblique bearing, so that the frictional resistance is reduced, and the stability and theservice life of the compressor are improved and prolonged.

Description

technical field [0001] The invention belongs to the technical field of compressor manufacturing, and in particular relates to a novel swash plate type automobile air conditioner compressor. Background technique [0002] The automotive air-conditioning compressor is the heart of the refrigeration system, providing power for refrigeration, lifting low-pressure gas to high-pressure gas, and compressing and transporting refrigerant vapor. Among them, the most widely used swash plate type automotive air-conditioning compressor. [0003] The structure of the existing compressor swash plate and the piston plate are installed separately. The piston plate is installed at the bottom of the cylinder body, and the swash plate is installed on the surface of the piston plate. Reciprocating linear motion. During the rotation of the swash plate, the contact between the swash plate and the piston plate is surface contact, which produces sliding friction, which has large friction resistance ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a new type of swash plate type automobile air-conditioning compressor, a device for optimizing the structure of the swash plate, and solve the problem of the gap between the swash plate and the piston plate when the piston in the existing compressor moves back and forth linearly inside the cylinder body. The frictional resistance of the sliding friction force is relatively large, and the swash plate wears faster
