Scroll plate and scroll compressor

Abstract

The invention provides a scroll plate and a scroll compressor. The scroll plate comprises a scroll plate base body, the side, facing a mating plate, of the scroll plate base body is a first side face, a scroll tooth is arranged on the first side face, the first side face is jointly composed of a first area and a second area, the first area is an area adjacent to an exhaust port of a compressor pump body, the second area is the area, except the first area, of the first side face, the first area is coated with a first wear-resisting layer, the second area is coated with a second wear-resisting layer, and the film thickness of the first wear-resisting layer is not equal to that of the second wear-resisting layer. According to the scroll plate and the scroll compressor, the film thicknesses of the wear-resisting layers corresponding to the first area and the second area correspondingly are unequal, and therefore the process difficulty can be reduced to a great degree on the premise of meeting the wear-resisting requirements of different areas, and the coating cost of the corresponding wear-resisting layers is reduced.

Description

technical field [0001] The invention belongs to the technical field of compressor manufacturing, and in particular relates to a scroll disk and a scroll compressor. Background technique [0002] The scroll compressor is a displacement compression compressor, and the key working parts include a fixed scroll and a moving scroll that meshes with it and moves relative to it. The profiles of the movable and static scrolls are both helical (helical teeth). The movable disc is eccentrically installed relative to the static disc with a difference of 180°. The end of the scroll body is in contact with the bottom of the opposite scroll body. A series of crescent-shaped spaces are formed between the moving and static plates. Driven by the crankshaft and driven by the anti-rotation mechanism, the movable scroll takes the center of the stationary disk as the center of rotation and performs high-speed rotational translation without rotation with the radius of rotation ρ, forming a contin...

AI Technical Summary

Problems solved by technology

[0006] Therefore, the present invention provides a scroll and a scroll compressor, which can overcome the disadvantages in the related art that the film thickness requirements of the wear-resistant layer at different positions of the scroll are consistent, the process is difficult to realize, and the coating cost is relatively high.
