Problems solved by technology

First, the screw groove and the tooth flanks of the star gear are a pair of meshing pairs with relatively high relative tangential velocity, and a certain gap is required to ensure that the meshing pair can work normally under normal conditions and with temperature changes Second, due to the many difficulties in the processing of the screw groove and the tooth flank of the star gear, general processing methods cannot guarantee that the screw groove and the tooth flank of the star gear can be meshed without clearance.
In addition, even if the meshing pair can ensure completely gap-free meshing at the beginning of operation, meshing gaps will still appear after a period of wear and tear.
[0005] The existence of the meshing gap increases the leakage of the unit displacement of the compressor, thereby increasing the exhaust loss of the compressor and reducing the efficiency of the compressor

Embodiment Construction

[0018] figure 1 and figure 2 They are the schematic diagrams of the straight tooth star wheel and the bevel tooth star wheel of the existing single-screw compressor respectively. In order to fully expand the tooth area of ​​the star wheel teeth, the space between the teeth of the existing star wheel at the tooth bottom has been compressed to the minimum limit. Therefore, there is no difference between the star wheel of the single screw compressor of the present invention and the existing star wheel at the tooth bottom.

[0019] see figure 1 and figure 2 As shown, from the bottom of the tooth to the top of the tooth, the tooth width of the existing star wheel remains unchanged or the tooth width gradually narrows, that is, the width L of the tooth top of the working tooth of the existing star wheel h Less than or equal to tooth bottom width L b .

[0020] The anti-bevel tooth star wheel structure of the single-screw compressor proposed by the present invention is as fol...

Abstract

The invention provides a single-screw compressor. The tooth form of a star wheel thereof is a reverse bevel edge with a tooth top wider than a dedendum width. The star wheel tooth of the single-screw compressor of the invention adopts a unique shape and greatly increases the volume of a screw channel under the condition of slightly increasing the length of a meshing pair leakage line, thus reducing the leakage rate of the unit air displacement of the compressor, lowering the air displacement loss of the compressor and improving the efficiency of the compressor. The single-screw compressor of the invention can be widely applied in various industries requiring compressors.

Description

technical field [0001] The invention belongs to the field of screw compressors, in particular to an energy-saving single screw compressor. Background technique [0002] Single-screw compressor is a new type of rotary compression machinery, its structure is very simple, only one screw and several star wheels. Single-screw compressors have many theoretical advantages, such as small size, large capacity, high pressure ratio, low noise, small vibration, and small air outlet pulsation, etc., and can meet the requirements of various industries. The ideal replacement product for formal compressors. [0003] The efficiency of single-screw compressors is largely controlled by the meshing clearance between the screw groove and the tooth flank of the star wheel. Because there is a gap between the screw groove and the tooth side of the star wheel, the compressed high-pressure gas will leak to the uncompressed low-pressure gas through this gap, thereby losing the compression work and r...
