Problems solved by technology

In this way, relative to the amount of oil discharged, the amount of oil inhaled will decrease, and the gradual reduction of oil inside the casing 1 will cause friction in various parts due to lack of oil, thereby reducing the life of the parts.

Abstract

A rotary shaft of sealed rotary compressor has a central axial oil channel, an eccentrical part at its lower end for closing to internal surface of cylinder, multiple oil spraying holes for spraying oil to compression unit, exhaust hole for exhausting the refrigerating gas from oil channel, and the grate with reverse cup shape and arranged at oil channel outlet for preventing oil from flowing out.

Description

technical field [0001] The invention relates to a rotary shaft of a sealed rotary compressor, in particular to a rotary shaft of a sealed rotary compressor which can prevent machine oil from flowing out. Background technique [0002] In general, hermetic rotary compressors suitable for home appliances such as air conditioners have a roller ring with a compression section eccentrically arranged on a rotating shaft integrated with a motor section, and the roller ring rotates in a cylindrical cylinder while sucking, compressing and cooling The gas is then discharged. Fig. 1 is a front sectional view of a hermetic rotary compressor in the prior art. As shown in Figure 1, the sealed rotary compressor of the prior art is equipped with a certain amount of machine oil and equipped with a suction pipe SP and a discharge pipe DP inside the casing 1. The stator 2 and the rotor 3 of the motor part are arranged. A rotating shaft 4 is inserted in the center, and a compression part is pr...
