Structure for decreasing friction loss of compressor

Abstract

The invention discloses a structure for reducing friction loss of a compressor. In a cylinder assembly having a closed space formed by a plurality of upper and lower bearings combined on both sides of the cylinder, and a rotating shaft upper partition inserted between the upper and lower bearings of the cylinder assembly and capable of dividing the internal space of the cylinder assembly, And in the compressor that compresses gas in the internal space of the cylinder assembly divided by the partition plate due to the rotation of the rotating shaft, the present invention forms a shaft that passes through the upper and lower bearings to reduce contact with the upper and lower bearings. The area of ​​the frictional contact area is reduced by the structure. Utilizing the present invention, the contact area between the upper and lower bearings and the rotating shaft subjected to the compressive force can be reduced during the process of rotating the diaphragm on the rotating shaft driven by the electric mechanism part and compressing the gas in the cylinder assembly, thereby reducing the friction. Loss and wear, improved compression performance and product reliability.

Description

technical field [0001] The present invention relates to a structure for reducing the frictional loss of a compressor, in particular to a structure that can act on the rotating shaft during the process of rotating and compressing gas in the internal space of the cylinder assembly when the partition plate on the rotating shaft is driven by the electric mechanism part. The friction loss caused by the radial gas compression force is the smallest structure to reduce the friction loss of the compressor. Background technique [0002] In general, a compressor is a machine that compresses a fluid. It usually consists of a sealed container with a predetermined internal space, an electric mechanism part installed in the sealed container to provide driving force, and a compression mechanism part driven by the electric mechanism part to compress the gas. Compressors can be divided into rotary compressors, reciprocating compressors, and screw compressors according to the structure of the...

Problems solved by technology

Since the force acting on the radial direction of the rotating shaft 20 is borne by the inner cylindrical surface of the shaft insertion hole 43 of the upper bearing 40 and the inner cylindrical surface of the shaft insertion hole 53 of the lower bearing 50 and the corresponding outer cylindrical surface of the rotating shaft 20, Therefore, this will increase the contact area between the rotating shaft 20 and the upper and lower bearings 40, 50, resulting in increased friction loss and wear, and reduced compression performance and product reliability.
