Optimal Contact Analysis of Meshing Pair for Single Screw Compressor

摘要

In order to improve the transmission performance and lubrication condition of the meshing pair of single screw compressor, the contact analysis of single screw compressor is carried out based on tooth contact analysis. The mathematical model of meshing pair contact is constructed, and the contact line equation is obtained based on conjugate principle. The contact analysis of meshing pair is carried out. The induced curvatures of points chosen on contact line are calculated, and results show that the contact surface is close, which is benefit for improving contact strength of tooth surface, and then the optimal center distance is obtained based on calculation induced angle between contact line direction and relative speed. In addition, the effect of meshing angle and closed angle on meshing performance of single screw compressor is obtained, results can offer effective basis for manufacturing the single screw compressor with better performance.
