Main frame of scroll compressor and scroll compressor

Abstract

The invention discloses a main frame of a scroll compressor and the scroll compressor. The main frame of the scroll compressor comprises a bearing pedestal; a cross-shaped sliding ring supporting face is arranged on one side face of the bearing pedestal and provided with at least two key grooves; and an oil groove is connected to the two sides of each key groove and used for lubricating relative movement between a cross-shaped sliding ring and the main frame. According to the technical scheme, the cross-shaped sliding ring supporting face of the main frame is provided with the oil groove, a certain amount of oil can be stored through the oil groove, the relative movement between the cross-shaped sliding ring and the main frame can be lubricated, relative movement between the key grooves and cross-shaped sliding ring convex keys can be lubricated better, the friction and collision strength and the power consumption of work done by the scroll compressor for overcoming friction are reduced, and therefore the reliability of the scroll compressor is improved.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a main frame of a scroll compressor and the scroll compressor. Background technique [0002] 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 main frame, a crankshaft, a motor, a housing, and the like. The movable scroll in the scroll compressor rotates 180° relative to the fixed scroll and is installed eccentrically. The motor in the scroll compressor drives the crankshaft so that the movable scroll orbits relative to the fixed scroll, thus forming a series of crescent-shaped spaces between the movable scroll and the wraps of the fixed scroll. During the orbiting process of the orbiting scroll, the crescent-shaped space on the outermost edge is constantly moving to the center, while the volume of the crescent-shaped ...

AI Technical Summary

Problems solved by technology

The Oldham slip ring with convex key is used to prevent the rotating motion of the movable scroll relative to the fixed scroll by matching the corresponding keyway, which will inevitably cause friction and collision between the Oldham slip ring and the main frame, resulting in unnecessary noise. Increase the power consumption of the compressor to overcome friction, and even cause the Oldham slip ring to be stuck
