Orbiting scroll and scroll compressors for scroll compressors

Abstract

The invention relates to a kinetic scroll for a scroll compressor. The kinetic scroll comprises a kinetic scroll end plate, kinetic scroll blades arranged on a first side of the kinetic scroll end plate, a boss arranged on a second side of the kinetic scroll end plate opposite to the first side, and a keyway formed on the second side of the kinetic scroll end plate. At least one raised part is formed on the second side of the kinetic scroll end plate, and the raised part contacts with a thrust surface of a crossed slip ring of the scroll compressor so that crossed slip ring overturn is prevented. Through the kinetic scroll, a cooperation precision of the kinetic scroll and the crossed slip ring is greatly improved, friction and collision between the kinetic scroll and the crossed slip ring are reduced, noise in scroll compressor running is reduced and scroll compressor work efficiency is improved. The invention also relates to a scroll compressor.

Description

technical field [0001] The present invention relates to a movable scroll used in a scroll compressor, more particularly, to a movable scroll capable of improving the working efficiency of the scroll compressor. It also relates to a scroll compressor comprising such an orbiting scroll. Background technique [0002] At present, scroll compressors in the prior art are widely used in refrigeration or heating equipment. Compressor is the core mechanism of refrigeration or heating equipment, and its working efficiency and operational stability will directly affect the working efficiency and operational stability of refrigeration or heating equipment. [0003] The scroll compressor realizes the periodic change of the compression chamber through the relative movement between the fixed scroll and the movable scroll, thereby converting the cooling medium from a low-pressure state to a high-pressure state. Therefore, the dynamic stability of the scroll compressor is an important fact...

AI Technical Summary

Problems solved by technology

[0005] In the scroll compressor of the prior art, due to the uneven or rough contact between the movable scroll and the Oldham slip ring, the relative movement in the longitudinal direction of the movable scroll and the Oldham slip ring will occur during the movement of the movable scroll, As a result, the Oldham slip ring collides with the movable scroll, causing the scroll compressor to generate greater noise during operation

This will adversely affect the operational stability of refrigeration equipment or heating equipment using this scroll compressor, and will also directly affect the working efficiency of the equipment.
