Problems solved by technology

Among them, the tangential force and axial centrifugal force are relatively large, and at the same time, the resultant force of tangential force, radial force and centrifugal force will be transmitted to the eccentric part of the compressor drive shaft, resulting in relatively large reaction force and friction force at the bearing of the drive crankshaft , which has a great impact on the performance and reliability of the scroll compressor

Abstract

The invention discloses a scroll plate of a scroll compressor. The scroll plate comprises a plate body, and a scroll tooth projected on the plate body, wherein the wall thickness of the scroll tooth is gradually changed in the projection direction of the scroll tooth. The invention further discloses a scroll compressor with the scroll plate, and an air conditioner provided with the scroll compressor. The scroll plate can reduce the force thereof in the radial direction and the axial direction, so that the friction power consumption of the scroll compressor is reduced, and the reliability of a crankshaft bearing is improved.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a scroll disk, a scroll compressor and an air conditioner. Background technique [0002] At present, scroll compressors are widely used in air conditioning systems and other fields due to their advantages such as simple structure, small size, light weight, low noise, high efficiency, and stable force. Generally, a scroll compressor includes a fixed scroll and a movable scroll that cooperate with each other, and a crankshaft that drives the movable scroll, wherein the fixed scroll and the movable scroll both include a base plate and a protrusion protruding from the base plate. The spiral teeth, and the spiral teeth and the base plate of the fixed scroll or the movable scroll are usually designed vertically. When the scroll compressor is working, the movable scroll mainly bears the centrifugal force brought by the crankshaft drive, the radial force and tangential force parallel to the r...
