Embodiment 1

[0043] The invention relates to a refrigerant compressor. Such as figure 1 As shown, the compressor includes a cylinder block 9, a front cover 3 located at one end of the cylinder block 9, a crank chamber 15 between the cylinder block 9 and the front cover 3, a valve plate assembly 10 at the other end of the cylinder block 9, and a control valve 13 and the cylinder head 12 are connected as a whole by screws 16 respectively.

[0044] The bearings in the front cover 3 and the cylinder block 9 support the drive shaft 2, the drive disc 4 is fixed on the drive shaft 2, the swash plate 6 is supported on the drive shaft 2 in the crank chamber 15, and the swash plate 6 moves along the drive shaft. The axis of 2 slides and relatively tilts. The swash plate 6 is installed on the drive plate 4 through a hinge mechanism 5 . The hinge mechanism 5 drives the swash plate 6 to swing, and at the same time, the hinge mechanism 5 makes the swash plate 6 and the drive shaft 2 rotate integrally...

Abstract

The invention provides a slide shoe(8) of a wobble plate compressor, which comprises a base body(18) made of magnesium alloy or magnesium-aluminium alloy, and a composite electroless powder coating formed on the surface of the base body(18). The composite electroless powder coating is applied on the surface of the slide shoe, so the problem of poor corrosion resistance of the magnesium alloy and the magnesium-aluminium alloy is solved, the rotary inertia of the compressor is lightened, and at the same time, durability and abrasion resistance of parts are ensured.

Description

technical field [0001] The invention relates to a component in a swash plate compressor, in particular to a sliding shoe used in the swash plate compressor. Background technique [0002] The working principle of compressors, especially those used in automotive air-conditioning systems, is as follows: the compressor converts the rotation of the drive shaft into the rotation of the piston in the cylinder bore through the swash plate and sliding shoes installed on the drive shaft in the crank chamber. Reciprocating motion, thereby compressing the gas. A pair of sliding shoes as sliding parts are placed between the swash plate and the piston to ensure the smooth operation of the swash plate and piston. In this type of compressor, large loads and high sliding speeds periodically act on the contact surfaces of the swash plate, pistons, and shoes. Pistons and swash plates are usually made of aluminum alloy, while sliding shoes are mostly made of steel. In order to make the compr...
