Abstract

A reciprocating compressor with lubrication intensified thrust bearing for decreasing the frictional loss and improving compression efficiency is composed of motor, crankshaft, connecting rod, piston, cylinder and thrust bearing. Said thrust bearing has multiple machine oil sucking slots arranged on its external circumferential surface at intervals for making the exhausted oil be flowing into compressor again to form a durable oil film.

Description

technical field [0001] The present invention relates to a reciprocating compressor having a lubricated enhanced thrust bearing. Background technique [0002] Generally speaking, a reciprocating compressor is a structure that constitutes the cooling cycle of various cooling devices such as refrigerators and air conditioners, and it is a compression device that compresses refrigerant. [0003] As shown in Figure 1, the existing reciprocating compressor includes: a body 1, which is integrally formed by an upper cavity 1a and a lower cavity 1b; 2 elastic supports; motor 4, which is composed of a stator 4a fixed to the lower end of the above-mentioned frame 3, and a rotor 4b rotatably installed in the above-mentioned stator 4a, and is used to generate driving force; crankshaft 5, which is pressed In the state of the rotator 4b of the above-mentioned motor 4, it is installed in the shaft hole 3" of the above-mentioned frame 3, and receives the driving force of the above-mentioned...
