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 engaged with the screw in the single-screw compressor is arranged obliquely, and it includes: a screw and two obliquely engaged screws Equal width 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 axes of the two star wheels The spatial position between them has the characteristic that they are not in the same plane; for single-screw compressors with equal-width teeth as star wheels, the corresponding screw teeth are also equal-width teeth.

[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, and 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 by the 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 areas [0002] The invention relates to a single-screw compressor, which belongs to the category of compressors and is used in industries and fields such as refrigeration, compression and transportation of gaseous media. technical background [0003] As far as the number of screws is concerned, screw compressors include single-screw and twin-screw. The twin-screw compressor is formed by meshing two identical screws, and its two axes are two non-overlapping parallel lines in the same plane. If one screw in a twin-screw compressor is rotated 90° relative to the other, the axes of the two screws are perpendicular to each other on different planes in space. Take one of the screws and the plane where the axis of the screw is located to intercept the cross-section of the other screw to engage, that is, to obtain the combination of a single screw and a star wheel, and to set another star wheel at a position rotated 180° around the single screw axis constitutes the cu...
