Problems solved by technology

[0004] However, in traditional scroll compressors, such as Chinese patent application 02129811.4 (published on April 2, 2003), the orbiting scroll member is rotatably in direct frictional contact with the bracket, the frictional contact area is large, and the direct friction The movable scroll parts and brackets caused by contact are seriously worn, resulting in reduced service life, reduced efficiency of scroll compressors, increased noise, and increased energy consumption
In addition, the lower end surface of the crankshaft is rotatably in direct frictional contact with the lower support frame, so the crankshaft and the lower support frame are severely worn, the life is reduced, the noise is increased, and the energy consumption is increased.

[0050] The following will refer to Figure 2B and image 3 The detailed structure of the friction-reducing member 101 for reducing the friction between the bracket 1 and the orbiting scroll member 2 and reducing their wear according to the first embodiment of the present invention will be described.

[0051] Such as Figure 2B As shown in , the friction reducing member 101 includes a support boss 26 and a circumferential groove 27 formed on the top surface of the support boss 26, the circumferential groove 27 is used to accommodate lubricant and / or lubricating oil. The support boss 26 is located on the upper surface 13 of the support 1 for supporting the orbiting scroll member 2. In order to increase the wear resistance, the top surface of the support boss 26 can be subjected to wear-resistant treatment, such as quenching, or carburizing treatment, etc. . The supporting boss 26 can be integrally formed on the upper surface of the bracket 1 , can also be welded on the upper ...

Abstract

The invention provides a scroll compressor, which comprises a compressor shell, a bracket, a still vortex component, a moving vortex component and an actuating component, wherein the bracket is arranged in the compressor shell; the still vortex component is fixed in the compressor shell; the moving vortex component can be rotatably supported on the bracket and is jointed with the still vortex component; and the actuating component is connected with the moving vortex component to drive the moving vortex component to rotate, wherein a friction reducing component for reducing the abrasion between the moving vortex component and the bracket is arranged between the moving vortex component and the bracket. Therefore, the friction condition between the moving vortex component and the bracket can be improved through the friction reducing component, thereby reducing the friction and abrasion between the moving vortex component and the bracket, reducing the energy consumption and noise of the scroll compressor, and ensuring that the running is steadier.

Description

technical field [0001] The invention relates to a scroll compressor, in particular to a scroll compressor capable of reducing the friction between a moving scroll part and a support. Background technique [0002] With the development of refrigeration and air-conditioning technology, it is necessary to improve the compression efficiency and work reliability of the compressor. Therefore, the development of energy-saving compressors has become one of the main directions for the development of refrigeration technology. [0003] The principle of scroll compressor refrigeration is to rotate the movable scroll around the center of the base circle of the fixed scroll, and gradually reduce the volume of the compression chamber formed by the engagement of the movable scroll and the fixed scroll , so as to achieve the purpose of compressing gas. Wherein the movable scroll part is directly supported on the bracket fixed in the compressor housing. In addition, one end (upper end) of t...
