Problems solved by technology

Therefore, in order to avoid the deformation of the cylinder, the welding of the cylinder is changed to the welding of the bearing. However, the method of bearing welding also has other hidden dangers, such as large deformation of the bearing end surface, and the problem of poor torque is prone to occur during the assembly process.

Abstract

The invention discloses a rotation compressor. The rotation compressor comprises a shell and an air cylinder component, wherein the air cylinder component comprises an air cylinder; the air cylinder is provided with a compression cavity; a slip sheet groove and a suction hole are formed in the air cylinder; the suction hole is formed in one side of the slip sheet groove; the air cylinder is provided with a first solid part and two first hollow parts which are arranged peripherally at intervals; one of the two first hollow parts is positioned at one side of the slip sheet groove and the suction hole, and the other one of the two first hollow parts is positioned at the other side of the slip sheet groove and the suction hole; the first solid part is positioned between the two first hollow parts and is opposite to the slip sheet groove; the outer peripheral wall of the air cylinder is provided with a first welding spot hole and two second welding spot holes; the first welding spot hole is opposite to the first solid part; the two second welding spot holes are respectively opposite to the two first hollow parts; the air cylinder is connected together with the shell in a welding mode via the first welding spot hole and the two second welding spot holes. The rotation compressor provided by the invention has improved performances.

Description

technical field [0001] The invention relates to the technical field of compressor manufacturing, in particular to a rotary compressor. Background technique [0002] It is pointed out in the related art that the sliding vane slots of the rotary compressor are greatly deformed during the assembly process, and tend to become narrower, which eventually leads to the jamming phenomenon of the rotary compressor. Since there are many links affecting the deformation of the slide groove, and there are many influencing factors, it is difficult to control. Among them, the three-point welding of the cylinder and the housing and the welding process of the lower housing are more prominent. Therefore, in order to avoid the deformation of the cylinder, the welding of the cylinder is changed to the welding of the bearing. However, the method of bearing welding also has other hidden dangers, such as large deformation of the bearing end surface, and the problem of poor torque is prone to occur...
