Problems solved by technology

[0006] refer to figure 1 , figure 2 As shown, the TH surface 2 (given the standard name) of the crankshaft 1 of the existing rotor compressor is perpendicular to the axis of the crankshaft 1. When the compressor is running, there is surface contact between the TH surface and the lower bearing, and no effective fluid flow can be formed. With dynamic pressure lubrication, there will be a large friction force between the TH surface 2 and the lower bearing 3, which will reduce the mechanical efficiency of the compressor and waste energy

Embodiment Construction

[0025] Ideal embodiments of the present invention that can specifically achieve the above objects will be described below with reference to the accompanying drawings. In the following description of the present embodiment, the same names and symbols are used for the parts having the same structure as the prior art, and the descriptions of these parts are omitted.

[0026] The rotary compressor of the present invention is composed of a casing, a power generation unit and a compression unit located inside the casing. The power generation part is located on the upper part of the compressor, the compression part is located on the lower part of the compressor, and the upper and lower parts of the casing are respectively equipped with a cap and a bottom cap to form a closed space inside the casing. A suction pipe for sucking the driving fluid is installed on one side of the casing, and the suction pipe is connected with a gas-liquid separator (accumulator) capable of separating lubr...

Abstract

The invention provides a rotor-typed compressor crankshaft TH surface structure; the TH surface of the invention is tangentially provided with a bevel; the bevel and the TH surface have an angle ranging from 0 DEG to 5 DEG; the distance from the intersection of the bevel and the TH surface to the external edge of a lower bearing is more than 0.5mm; the angle between the intersection and the symmetrical line of the TH surface is ranging from 0 DEG to 90 DEG; the friction force between the TH surface and the lower bearing is reduced, the mechanical efficiency of the compressor is improved, and the energy is saved.

Description

1. Technical field [0001] The invention relates to a crankshaft of a rotor compressor, in particular to a TH surface structure of a crankshaft of a rotor compressor. 2. Background technology [0002] A compressor is a mechanical device that can compress driving fluids such as air and refrigerant after receiving power transmitted by a power generating device such as a motor (motor) or a turbine (turbine), so that the pressure of the driving fluid raised. Such compressors are used in a wide variety of products ranging from general home appliances such as air conditioners and refrigerators to factory equipment. [0003] The above-mentioned compressors can be classified into positive displacement compressors (positive displacement compressors) and turbo compressors (dynamic compressors or turbo compressors) according to compression forms. Among them, positive displacement compressors are mostly used in factories, which use a compression method that increases pressure by reduci...
