[0008] The wear-resistant lubricating coating is a polytetrafluoroethylene coating fixedly arranged on the outer side of the wear-resistant disc body.

[0009] The thickness of the wear-resistant lubricating coating is 0.1-2.0 mm.

[0010] An internal thread is formed on the inner side of the mounting hole.

[0011] A convex ring is fixedly arranged on the outer side of one end of the mounting hole away from the swash plate seat, and the internal thread is continuously arranged on the inner sides of the mounting hole and the convex ring.

[0012] A second chamfer is provided on one end of the mounting hole corresponding to the swash plate seat.

[0013] The outer side of the wear-resistant disc body is provided with a first chamfer.

[0014] Beneficial effects of the utility model: In the utility model, the edges of the wear-resistant disc body are slidably connected to the corresponding sliding shoes by arranging a wear-resistant lubricating coating on both sides, which can reduce the friction and wear between the wear-resistant disc body and the sliding shoes, improve the service life, extend the maintenance cycle, and reduce the noise during operation.

[0019] like Figure 1 and 2As shown, the wear-resistant disk for automobile air-conditioning compressor includes a wear-resistant disk body 1 with an annular structure, a circular mounting hole 7 is concentrically arranged inside the wear-resistant disk body 1, and annular wear-resistant lubricating coatings 2 are arranged on both sides of the edge of the wear-resistant disk body 1, and the width of the wear-resistant lubricating coating 2 is not less than the width of the sliding shoe; in this embodiment, the wear-resistant lubricating coating 2 is arranged on both sides of the edge of the wear-resistant disk body 1 to contact and slide with the sliding shoe, which can reduce the friction and wear between the wear-resistant disk body 1 and the sliding shoe, improve the service life, extend the maintenance cycle, and reduce the noise during operation.

[0020] In some embodiments, as a specific implementation of the wear-resistant lubricating coating 2, the wear-resistant lubricating coating 2 is a polytetrafluoroethylene coating fixedly arranged on the outside of the wear-resistant disk body 1. The polytetrafluoroethylene coating is a high molecular polymer obtained by polymerization of tetrafluoroethylene as a monomer. It has an extremely low friction coefficient and is wear-resistant. Specifically, the thickness of the wear-resistant lubricating coating is 0.1 to 2.0 mm.

[0021] In some embodiments, an internal thread is provided on the inner side of the mounting hole 7, and an external thread matching the internal thread needs to be provided on the corresponding swash plate seat.
