Problems solved by technology

[0011] However, in the above-mentioned rotary compressor, when the refrigerant gas is compressed, the end of the rolling piston 9 is in contact with the main bearing 7 and the auxiliary bearing 8, so that mechanical wear and an increase in the load of the compressor inevitably occur, resulting in a loss of performance of the compressor. and reduced reliability, thereby reducing service life

Abstract

A structure for decreasing load of vortex-type compressor is composed of rolling piston, primary bearing and secondary bearing, and features that a recess is made on at least surface of them to decrease the contact area, so reducing friction and load.

Description

technical field [0001] The invention relates to a rotary compressor, in particular to a load-reducing structure of the rotary compressor. Background technique [0002] figure 1 is a sectional view of a conventional rotary compressor, figure 2 is an oblique view of a main or auxiliary bearing of conventional technology, image 3 An oblique view of a rolling piston of conventional technology. [0003] Refer to the above Figure 1 to Figure 3 It can be seen that a traditional compressor is composed of a casing 1, a motor provided inside the casing 1 to provide power, and a compression structure driven by the motor to compress refrigerant. The motor consists of a stator 2 and a rotor 3 fixed in a casing 1 . The compression structure is set in the casing 1, located at the lower part of the rotor 3, and consists of the rotating shaft 4, the eccentric shaft 4a below it, the gas compression chamber P, the cylinder 5, the main bearing 7, the auxiliary bearing 8 and the rolling ...
