Abstract

The invention provides a rotary shaft, a compressor and an air conditioner. The rotary shaft comprises a rotary shaft body, an eccentric part connected with the rotary shaft body and a buffering part arranged on a thrust surface of the eccentric part to reduce abrasion of the thrust surface. The buffering part arranged on the thrust surface of the eccentric part achieves a movable buffering effect in the axial direction, the rotary shaft can be effectively prevented from moving in the axial direction, thrust sound is eliminated, the problem that the thrust surface has friction with other components of an air cylinder, consequently the thrust surface has abrasion, and the reliability of the rotary shaft is lowered is effectively avoided, and therefore the stability and reliability of the rotary shaft are effectively improved.

Description

technical field [0001] The invention relates to the technical field of air conditioner equipment, in particular to a rotating shaft, a compressor and an air conditioner. Background technique [0002] In recent years, with the rapid development of rotary compressors, customers have higher requirements for reliability and stability while pursuing high energy efficiency of compressors. In the prior art, during the working process of the rotary compressor, the crankshaft is driven by the rotor to rotate at a high speed. The radial constraints are the inner hole of the upper flange and the inner hole of the lower flange, and the axial constraints are the lower end surface of the upper flange and the lower surface of the lower flange. The common design of the upper end face of the flange is: the eccentric portion of the crankshaft directly contacts the upper end face of the lower flange to support the crankshaft. The common design of the thrust surface of the crankshaft cannot ens...
