Plane cross slip ring for scroll compressor

Abstract

The invention discloses a plane cross slip ring for a scroll compressor. The plane cross slip ring is in a plane layout structure; working main bodies are two pairs of lug bosses crossly arranged on the plane cross slip ring; the spatial position of a working plane is positioned between two end planes of the plane cross slip ring; one pair of the lug bosses arranged on the plane cross slip ring are positioned at the excircle side of the plane cross slip ring, and the other pair of the lug bosses are positioned at the inner circle side of the plane cross slip ring; the working planes of the lug bosses are mutually perpendicular; the working planes of the first pair of the lug bosses of the plane cross slip ring are attached to the friction surfaces of a pair of lug bosses of a static scroll plate, and the working planes of the second pair of the lug bosses are attached to the friction surfaces of a pair of lug bosses of a dynamic scroll plate; and the working planes of the lug bosses of the plane cross slip ring, the friction surfaces of the dynamic scroll plate and the friction surfaces of the static scroll plate are all parallel to a central axis of the plane cross slip ring, thus the dynamic scroll plate takes plane circular motion under the driving of a bent axle. The invention effectively solves the problems of vibration, noise and short life of the traditional cross slip ring without a protruding guide slide block of the traditional cross slip ring.

Description

Technical field: [0001] The invention relates to the field of scroll machinery. In particular, the present invention relates to a unique flat Oldhams slip ring used in these scroll machines. Background technique: [0002] Such machines, commonly referred to in the art as "scroll" machines, are used for the transport of various types of fluids. This scroll machine can be made into a scroll expander, a scroll compressor, a scroll engine, a scroll pump and the like. The features of the present invention are suitable for any of these machines. However, for purposes of illustration, the disclosed embodiments are in the form of hermetic refrigerant scroll compressors. [0003] Scroll compressors are increasingly used as compressors in refrigeration and air conditioning applications. Generally, a scroll compressor is mainly composed of a movable scroll, a fixed scroll, an Oldham slip ring, a bearing housing, a crankshaft, a motor, a sealed casing, and the like. A scroll arrang...

AI Technical Summary

Problems solved by technology

The result is increased noise and vibration in the scroll compressor and shortened compressor life

At the same time, it is precisely because of the existence of these four keys that the Oldham slip ring is likely to repeatedly collide between the end plate of the movable scroll and the end plate of the fixed scroll during the working process, causing periodic tilting vibration noise

Not only does this shorten the life of the compressor, it also emits unwanted vibrations and noises constantly
