Problems solved by technology

However, the lower thrust surface is designed eccentrically, the point of force is not on the center of gravity, the radius of rotation is large, and it is sliding friction, and the lubrication effect is not ideal, resulting in more friction work consumed, and the performance of the compressor is reduced. Further improvement in performance has a greater impact

Abstract

The invention discloses a compressor, comprising a shell, a compression mechanism, a support rod, a support base and a thrust component; the compression mechanism is arranged in the shell and comprises a main bearing, an air cylinder, a secondary bearing and a crankshaft; the main bearing is arranged at the top of the air cylinder and the secondary bearing is arranged at the bottom of the air cylinder; the crankshaft penetrates through the main bearing, the air cylinder and the secondary bearing in sequence; a central hole is formed inside the crankshaft; a spiral groove is formed in the peripheral wall of the support rod; at least one part of the support rod stretches into and is fixed in the central hole; the support base is arranged at the lower end of the secondary bearing and is constructed to enable a lubricating oil at the bottom of the shell to enter a clearance between the support rod and the central hole; the thrust component is arranged at the lower end of the support rod; the bottom of the thrust component is propped against the support base; and the contact centre of the thrust component and the support base is located on a rotary central line of the crankshaft. According to the embodiment of the invention, the compressor is high in reliability and has good performance.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor. Background technique [0002] It is pointed out in the related art that the crankshaft and the rotor of the compressor will eventually act on the lower thrust surface of the crankshaft due to various downward forces such as gravity and downward electromagnetic pull. However, the lower thrust surface is designed eccentrically, the force point is not on the center of gravity, the radius of rotation is relatively large, and it is sliding friction, and the lubrication effect is not ideal, resulting in more friction work consumed, the performance of the compressor is reduced, and the compressor Further improvement in performance has a greater impact. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, the present invention needs to provide a compressor wit...
