Problems solved by technology

[0003] Although the structure mentioned in the above patent can reduce the friction loss between parts, there may be problems in the effect of reducing friction loss and the stability of the whole machine
As far as the structure in the publication number CN1566696A is concerned, there is already a lot of refrigeration oil at the position of the Oldham slip ring, and the effect of opening the oil guide groove to reduce wear may not be obvious
However, the structure disclosed in the application number 201110304571.0 is less stable than the Oldham slip ring anti-rotation structure

Embodiment Construction

[0025] The core of the invention lies in disclosing an Oldham slip ring, which can not only prevent the rotating disk from rotating, but also reduce the friction loss between components.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Abstract

The present invention discloses a cross slip ring which is arranged between a movable scroll plate and an upper bracket to support the floating of the movable scroll plate. A rolling friction mechanism is assembled on a fitting surface f the cross slip ring, the movable scroll plate and the upper bracket, so that the friction loss between parts is reduced. The rolling friction mechanism can reduce the friction loss between the cross slip ring and the movable scroll plate through a mode of the rolling friction instead of the sliding friction by specifically assembling a ball on an end face where the cross slip ring is cooperated with the movable scroll plate. The ball is instead of the end face of the cross slip ring, and processing procedures are reduced. The structure of the scheme is simple and the assembling is easy. The invention also discloses a scroll compressor using the cross slip ring. The friction between the cross slip ring and the movable scroll plate and the upper bracket is effectively reduced. The contact friction mode between the parts is changed, and the friction loss between the parts is reduced.

Description

technical field [0001] The invention relates to the technical field of scroll compressors, in particular to a scroll compressor and an Oldham slip ring thereof. Background technique [0002] At present, the Chinese invention patent application with the publication number CN1566696A discloses a structure for reducing the wear of the Oldham slip ring. In the structure, the Oldham slip ring supports the moving plate, and an oil guide groove is opened between the Oldham slip ring and the bracket keyway to reduce the wear of the Oldham slip ring. wear and tear. In addition, the Chinese invention patent with application number 201110304571.0 discloses a structure for reducing the friction between the rotor and the bracket. A flat ball structure is assembled between the disc and the upper bracket to reduce wear between parts. [0003] Although the structure mentioned in the above patents can reduce the friction loss between parts, there may be problems in the effect of reducing f...
