Wear reducing structure of closed compressor

Abstract

The wear reducing structure of closed compressor includes cylinder assembly, partition board and guide board. The cylinder assembly has inner space communicated with the suction port and the exhaust port; the partition board separates the inner space into several sealed spaces and makes the cylinder assembly possess suction port and exhaust port; and the guide board moving linearly relatively to the partition board is combined to the cylinder assembly and can slide along the axis. Several guide board channels are formed on the cylinder assembly for the guide boards to be inserted in the axis direction, and guide board supporting lugs support the guide board in the fluid compressing direction. The guide board supporting lugs with stepped or inclined outer front end can maintain relatively thin bearing boards and support guide boards stably, and this can reduce the wear of guide boards and bearing boards and raise the efficiency of compressor.

Description

technical field [0001] The invention relates to a compressor, in particular to a structure for reducing wear of a hermetic compressor. The guide plate moves up and down with the partition plate, which can reduce the wear of the guide plate. Background technique [0002] Generally, in the structure of the guide plate type compressor, the internal space of the cylinder is divided into the suction area and the compression area by crimping the guide plate to the rotating body. In the above state, the rotating body is rotated to continuously switch between the suction area and the compression area, and the compressed fluid is sucked and then the fluid is discharged.

The compression mechanism of the guide plate type hermetic c...

Problems solved by technology

[0008] In the prior art hermetic compressor with the above-mentioned structure, there are following disadvantages: the first guide plate 6A and the second guide plate 6B move up and down in the guide plate groove 3b along with the curved surfaces on both sides of the partition plate 5

In the above process, the outer surfaces of the first guide plate 6A and the second guide plate 6B contact the inner surface of the guide plate groove 3b to generate frictional resistance. Considering the frictional resistance, the input power of the motor needs to be increased, which eventually increases the wear and tear.
