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

Abstract

The invention discloses a rotary compressor, a gas compression system, a refrigeration system and a heat pump system. The rotary compressor comprises an air cylinder, a crankshaft, a piston, a main bearing, an auxiliary bearing, a sliding piece and a rocking block, wherein the piston sleeves the eccentric part of a crankshaft, and the piston is rotatably arranged in an air cylinder; a clamping structure which is used for limiting circumferential direction movement generated between the crankshaft and the piston is arranged between the eccentric part of the crankshaft and the piston, and a sliding piece groove is formed in the air cylinder, the sliding piece is installed in the sliding piece groove, the rocking block and the tip end of the sliding piece wind around a first axis in a hingedmode, the first axis is parallel to the axis of the air cylinder, and the rocking block is abutted against the outer circle face of the piston in a pressed mode. According to the rotary compressor, the lubricating state between the sliding piece and the friction pair of a cam part is improved, the friction power consumption between the friction pair of the cam part and the sliding piece is greatlyreduced, and friction loss between the eccentric part of the crankshaft and the piston can be effectively reduced.

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...
