Problems solved by technology
Since the star wheel is driven by the screw to rotate at high speed, there is high-speed sliding friction between the star wheel and the screw meshing surface, so a large amount of heat and friction loss will be generated between the two tooth surfaces, which is insufficient.

The invention discloses a long-service-life single-screw compressor. The long-service-life single-screw compressor comprises a measuring device used for measuring the angular displacement of a screw rod, a pneumatic synchronous clutch arranged on a shell and connected with a star wheel, a driving device arranged on the shell and used for driving the pneumatic synchronous clutch to rotate, and a control device used for receiving the detection signal sent by the measuring device and controlling the rotating speed of the driving device to be synchronous with the rotating speed of a main shaft, so that the control device controls the pneumatic synchronous clutch to act to be connected with the driving device, and the star wheel and the screw rod rotate according to the relation that the respective tooth ratio is equal to the respective rotating speed ratio. According to the long-service-life single-screw compressor, due to the fact that passive rotation of the star wheel is changed into active following rotation, the meshing face of the screw rod and the star wheel can be almost not in contact, small-gap even zero-gap transmission can be kept for a long time, the service life of the single-screw compressor is greatly prolonged, and due to reduction of friction power consumption, the single-screw compressor is more energy-saving and lower in operation cost.
Description
technical field [0001] The invention relates to the technical field of compressors, in particular to a long-life single-screw compressor. Background technique [0002] Single-screw compressor, also known as worm compressor, is essentially a special application of torus-enveloping worm pair. The number of worm heads (number of teeth) is Z1, commonly used Z1=6, and the number of worm gear teeth Z2, commonly used Z2=11. All single-screw compressors currently on the market use the screw (worm) as the active part and the star wheel (worm gear) as the passive part. The motor is directly connected to the screw shaft through the coupling to drive the screw to rotate at high speed, and the screw relies on its own special helical surface to drive the meshing star gear teeth to rotate around the star gear shaft in a certain proportion. Because the star wheel is driven by the screw to rotate at high speed, there is high-speed sliding friction between the star wheel and the screw meshin...
