Support assembly of movable scroll plate of air conditioner compressor

Abstract

The invention discloses a support assembly of a movable scroll plate of an air conditioner compressor. The support assembly of the movable scroll plate of the air conditioner compressor is characterized in that the support assembly comprises a tray and a wear-resistant plate, wherein the wear-resistant plate is attached to the position above the tray; the wear-resistant plate is provided with sixthrough holes, and the through holes are close to the inner circle of the wear-resistant plate; the wear-resistant plate is provided with an arc-shaped opening, and the arc-shaped opening is close tothe edge of the outer circle of the wear-resistant plate; and a pair of first fixing holes are oppositely formed in the wear-resistant plate. According to the support assembly, by means of returning of part of gas, friction generated between the bottom of the movable scroll plate and other components is reduced under the effect of buoyancy force; and wear generate among the components is also reduced through a buffer space formed between the unlevel surface of a support ring and the wear-resistant plate. Meanwhile, it is guaranteed that when being impact by axial force, the movable scroll plate cannot lose balance easily; the gas leakage problem is reduced; and it is guaranteed that production is implemented orderly.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a support assembly for a movable scroll of an air conditioner compressor. Background technique [0002] A scroll compressor is a volumetric compression compressor, and the compression components are composed of an orbiting scroll and a fixed scroll. Its working principle is to use the relative orbital motion of the movable and static scrolls to form a continuous change in the closed volume to achieve the purpose of compressing the gas. In the process of realization, the gas in the crescent-shaped space generates axial force and moment on the movable scroll, which causes the movable scroll to lose balance; during the relative revolution of the movable and static scrolls, wear with each component; and its scroll The machining accuracy of the rotary body profile is very high. The flatness of the end plate plane and the perpendicularity between the end plate plane and the side wall o...

Problems solved by technology

In the process of realization, the gas in the crescent-shaped space generates axial force and moment on the movable scroll, which causes the movable scroll to lose balance; during the relative revolution of the movable and static scrolls, wear occurs with various components; and its scroll The machining accuracy of the rotary body profile is very high. The flatness of the end plate plane and the perpendicularity between the end plate plane and the side wall of the scroll body must be controlled at the micron level. Special precision processing equipment and precise self-aligning assembly technology must be used.
