Abstract
The utility model relates to a swash plate structure of an automobile air conditioner compressor, which comprises a swash plate body, wherein a shaft hole is formed in the center of the swash plate body, long-strip-shaped grooves are formed in the opposite inner sides of a group of shaft holes, two semi-annular grooves are symmetrically formed in the centers of disk surfaces on two sides of the swash plate body, a plurality of fixing rods are arranged in the semi-annular grooves and perpendicular to the shaft hole, and balls are sleeved outside the fixing rods. The utility model replaces the sliding friction of the traditional swash plate by embedding the ball on one side of the swash plate and making the ball contact with the rolling friction of the piston, thereby reducing the abrasion of the swash plate, reducing the resistance of the swash plate to rotate and prolonging the service life of the swash plate of the air-conditioning compressor; and the characteristic that the swash plate periodically rotates and only partial position of the circumference is in frictional contact with the piston is utilized, the purpose can be achieved by only arranging a small amount of balls on one side of the swash plate, and the swash plate is simple in structure and easy to produce.
Description
Technical Field
The utility model relates to an automobile air-conditioning compressor swash plate structure, and belongs to the technical field of automobile air-conditioning compressors.
Background
The automobile air-conditioning compressor can provide power for an automobile refrigeration system, low-pressure gas is changed into high-pressure gas through compression, refrigerant steam is conveyed, the compressor can be divided into a crankshaft connecting rod type compressor, an axial piston type compressor, a rotary blade type compressor and a vortex type compressor, and the axial piston type compressor is commonly a rocker plate type compressor and a swash plate type compressor.
Among them, the swash plate type compressor can be easily miniaturized and lightened, and can be operated at a high rotation speed.
At present, the swash plate of most compressors is in surface contact with the piston, and the friction resistance is large in the rotating process, so that the wear of the swash plate is serious.
There is a need for a wear resistant swash plate structure for automotive air conditioning compressors.
