AI Technical Summary
Technical Problem
In compressor design, in order to optimize the size of the motor assembly, the reduction in the size of the rotor component leads to a decrease in the area of the crankshaft and the rotor mating section, which in turn leads to an intensified crankshaft wear, affecting operating stability and life.
Method used
By adding a crankshaft mating cover to the crankcase and providing a rotating groove on its first side, the countershaft is mated to increase the positioning mating area of the crankshaft, stabilize the crankshaft and reduce wear.
Benefits of technology
It effectively improves the operating stability and life of the crankshaft, meets the dimensional optimization requirements, and reduces the impact on the original compressor performance.

Abstract
The invention discloses a compressor and refrigeration equipment, and relates to the technical field of compressor structures, the compressor comprises a crankcase, a crankshaft and a crankshaft matching cover, the crankcase comprises a piston cylinder and a crankshaft operation area located on one side of the piston cylinder; the crankshaft comprises a main shaft and an eccentric shaft located at the end of the main shaft, the eccentric shaft extends into a crankshaft operation area, and an auxiliary shaft is further arranged at the end, away from the main shaft, of the eccentric shaft. The crankshaft matching cover covers the crankshaft operation area and comprises a main body, the main body is provided with a first side and a second side which are opposite, the first side of the main body faces the crankcase, a rotating groove is formed in the first side of the main body, and the rotating groove is in rotating fit with an auxiliary shaft arranged at one end of the crankshaft. The invention aims to improve the conditions of poor operation stability and large abrasion loss of the crankshaft when the matching size of a main shaft and a motor in the compressor crankshaft is small.
