Problems solved by technology

However, the needle roller structure has extremely high requirements on reliability. Due to the sharp increase of the contact stress between the needle roller and the piston, it poses a challenge to the wear resistance of the needle roller material, and the needle roller structure is prone to needle roller jamming failure. Once the needle roller fails, the needle roller will wear out sharply until the compressor is stuck and fails, so there is room for improvement

Description

technical field [0001] The invention belongs to the technical field of compressor manufacturing, and in particular relates to a rotary compressor, a gas compression system with the rotary compressor, a refrigeration system with the rotary compressor and a heat pump with the rotary compressor system. Background technique [0002] In the compressor mechanism, the friction loss between the tip of the slide plate and the outer surface of the piston is relatively large. In order to reduce this friction loss, in the related art, a needle roller is installed at the tip of the sliding plate. The purpose of this structure is to change the sliding friction between the piston and the sliding plate into rolling friction, and the friction power consumption is effectively reduced. However, the needle roller structure has extremely high requirements on reliability. Due to the sharp increase of the contact stress between the needle roller and the piston, it poses a challenge to the wear re...
