Abstract

The invention discloses a centering method of a compression mechanism part. The compression mechanism part includes: a crankshaft, the crankshaft includes a crankshaft main body and two eccentric parts, at least one of the two eccentric parts is processed separately from the crankshaft main body; Partition, the middle partition is located between two cylinders, each cylinder is equipped with a piston on the corresponding eccentric part, and the middle partition supports the crankshaft; the upper end cover and the lower end cover are respectively arranged on the There are gaps between the upper end cover and the lower end cover and the crankshaft on the two cylinders and the crankshaft; the method of aligning the core is to first pass the crankshaft main body with at most one eccentric part through the middle partition, and then put the remaining eccentric The parts are assembled on the main body of the crankshaft, and the two pistons are sleeved on the corresponding eccentric parts, and the two cylinders are fixed on the middle partition. According to the method for aligning the compression mechanism part of the present invention, the assembly operation is easy, the manufacturing process is good, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a core-aligning method for a compression mechanism. Background technique [0002] Compared with the single-cylinder rotary compressor, the multi-cylinder rotary compressor can generally operate at a low speed of 12rps to 120rps, and has advantages in operation vibration. In recent years, in order to cope with large-scale installations, the application of 10HP class variable frequency motors has progressed; or to increase the heating capacity to achieve rapid heating effects, etc., many merchants in the industry are pursuing high-speed products, that is, the compressor. The maximum operating speed is increased from 120rps to 150rps, or even 200rps. [0003] The vibration and reliability of the compressor at such a high speed are very challenging, so most of this type of products will consider the use of multi-cylinder compressors, the most common is the use of dual-cylinder c...
