Problems solved by technology

[0004] The main problem of the current single-screw compressor is the service life of the star wheel, and the service life of the star wheel is related to the rigidity of the star wheel bracket, so increasing the bracket stiffness is beneficial to prolong the service life of the star wheel

Embodiment 2

[0008] According to Embodiment 2 of the present invention, the oblique star-wheel single-screw compressor is characterized in that the star-wheel meshing with the screw in the single-screw compressor is arranged obliquely, and it includes: a screw and two obliques meshing with it. Constant-width tooth star wheel; a body, and the screw shaft and star wheel shaft supported by the body; two star wheels are distributed obliquely on both sides of the screw; between the central axis of the two star wheels and the axis of the screw and between the central axis of the two star wheels The space position between the two has the characteristic of not being in the same plane; the single-screw compressor with equal-width teeth as the star wheel has the same tooth profile of the corresponding screw.

[0009] According to Embodiment 3 of the present invention, the single-screw compressor includes a main shaft and a body, and the main shaft frame is supported on a bearing in the body. It is chara...

Abstract

The invention relates to an oblique star wheel single-screw compressor, which is characterized in that star wheels which are meshed with a screw in the single-screw compressor are arranged obliquely. The oblique star wheel single-screw compressor comprises the screw, two oblique star wheels which are meshed with the screw, a machine body, and a screw shaft and a star wheel shaft which are born bythe machine body, wherein the two star wheels are obliquely distributed on both sides of the screw; axes of the two oblique star wheels and an axes of the screw, and the axes of the two star wheels, are not coplanar mutually. The single-screw compressor has the advantages of large air displacement, small vibration, low noise, low energy consumption, short compression stroke, small volume, high volumetric efficiency and so on.

Description

[0001] Involved [0002] The invention relates to a single-screw compressor, belonging to the compressor category, and used in industries and fields such as refrigeration, compression and transportation of gas media. technical background [0003] In terms of the number of screws, screw compressors have single-screw and twin-screw types. The twin-screw compressor is formed by the meshing of two identical screws, and its two axes are two parallel lines that do not overlap in the same plane. If one screw in a twin-screw compressor is rotated 90° relative to the other screw, the axes of the two screws are perpendicular to each other in different planes in space. Take one screw and the axis of the screw to intercept the cross-section meshing of the other screw to obtain the combination of a single screw and a star wheel. The other star wheel is set at a 180° rotation around the single screw shaft to constitute the current mainstream Single screw compressor. The above two situations c...
