When the sealing performance of the single-screw compressor is ensured, the first star wheel sheet can reduce the action and friction of the rear side surface of the screw groove on the rear side surface of the first star wheel sheet when rotating, and the condition that the service life of the single-screw compressor is influenced by the abrasion of the first star wheel sheet is avoided.)

1. A star wheel sheet abrasion-free long-life single screw compressor comprises a shell, wherein a rotor system and a star wheel system are arranged in the shell; the rotor system comprises a screw, and a screw groove is formed in the screw; the star wheel system comprises two plane star wheels with central symmetry, and is characterized in that,

each planar star wheel comprises a star wheel frame, a star wheel sheet is arranged on the star wheel frame and covers the star wheel frame, the star wheel sheet and the screw thread groove form a first meshing pair, and the star wheel sheet is made of non-metal materials;

the auxiliary power-assisted meshing pair is formed by the auxiliary star wheel sheet and the auxiliary spiral groove.

2. The abrasion-free long-life single-screw compressor with the star wheel sheets as claimed in claim 1, wherein spring devices and fixing devices are arranged below the first star wheel sheet and the star wheel frame, and the spring devices are respectively connected with the fixing devices and the auxiliary star wheel sheet; when the rotor system operates, the auxiliary star wheel sheet keeps close under the action of the spring device.

3. The abrasion-free long-life single-screw compressor with the star wheel blades as claimed in claim 2, wherein an auxiliary power-assisted meshing positioning pin is arranged on the star wheel frame, and the spring device is arranged on the auxiliary power-assisted meshing positioning pin.

4. The abrasion-free long-life single-screw compressor with the star wheel blades as claimed in claim 3, wherein the auxiliary power-assisted meshing positioning pin is made of wear-resistant metal, the front end of the positioning pin is a part of an auxiliary meshing pair, and the front end of the positioning pin is always tightly attached to the bottom of the auxiliary screw groove under the action of a spring.

5. A wear-free long-life single screw compressor with star wheel blades as claimed in any one of claims 1 to 4, wherein said first star wheel blades are uniformly arranged on said star wheel frame.

6. The abrasion-free long-life single-screw compressor with star wheel blades as claimed in any one of claims 1 to 4, wherein the shape of the auxiliary star wheel blades is adapted to the shape of the auxiliary screw grooves.

7. The wear-free long-life single-screw compressor with star wheel blades as claimed in any one of claims 1 to 4, further comprising a cooling and lubricating system and a control system.
