Problems solved by technology

[0003] However, since the balance chamber is located below, the lubricating oil flowing out from the lubricating oil groove on the outer peripheral surface of the eccentric part will flow into the balance chamber, thereby deteriorating the starting torque of the compressor, and at the same time, too much oil in the balance chamber will cause the rest of the compression mechanism to move Components are not adequately lubricated, increasing compression mechanism wear
Moreover, the balance weight in the prior art has the phenomenon of secondary compression of the gas in the balance chamber, resulting in low energy efficiency of the compressor

Abstract

The invention discloses a rotary compressor and a refrigeration circulating device provided with the rotary compressor. The rotary compressor comprises a shell, a compressing mechanism and a balance block, wherein the compressing mechanism is arranged inside the shell and comprises an air cylinder, a main bearing, an auxiliary bearing, a baffle plate and a crank shaft, the main bearing is arranged on the air cylinder, the baffle plate is arranged below the air cylinder, so that a compressing cavity is limited among the main bearing, the air cylinder and the baffle plate, the auxiliary bearing is arranged below the baffle plate, so that a balance cavity is limited between the auxiliary bearing and the baffle plate, the crank shaft is provided with an eccentric part, a lubrication oil groove is formed in the peripheral surface of the eccentric part, the lubrication oil groove and the bottom surface of the eccentric part are spaced from each other, the balance block is arranged on the crank shaft and located in the balance cavity, and the radial minimum distance between the balance block and the balance cavity is 0.2mm. The rotary compressor disclosed by the invention can effectively improve oil deposition phenomenon of the balance cavity, and meanwhile, the balance block can not carry out secondary compression on coolant in the balance cavity.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a rotary compressor and a refrigeration cycle device with the rotary compressor. Background technique [0002] The traditional single-cylinder rotary compressor has an eccentric part, so during the rotation of the crankshaft, the eccentric part and the piston sleeved outside the eccentric part have a large centrifugal force when rotating, and at the same time due to the deflection of the crankshaft in high-speed operation Effect, which will increase the wear and vibration of the crankshaft, resulting in reduced compressor efficiency. At present, a solution is to adopt the intermediate shaft balance weight scheme, that is, add a balance weight on the crankshaft for balancing the eccentric part and the piston, and the balance weight is arranged in a balance cavity between the eccentric part and the crankshaft countershaft section (that is, located below the eccentric part), thereby impr...
