Experimental studies of the tooth wear resistance with different profiles in single screw compressor

The single screw compressor has been used in gas compression and refrigeration systems. However, the durability is not good as expected for the wear of its meshing pair. In order to improve the wear resistance and operation life, several new profiles of meshing pair have been proposed, but most of these new profiles have not been applied in products or verified by experiments. In this paper, an eccentric wheel abrasion test device was designed to investigate the wear resistance of different meshing pairs. Results show that dispersing abrasion area and making connect area continuous can improve wear resistance.
