Abstract
To make research on contact stress between worm and worm gear under different circumstances, and the relationship between the torsion angle of the worm and the driving torque,solid models with precise tooth surface of a ZA worm and worm gear were established based on tooth surface equations. Using these models, finite element analysis of contact was performed with ANSYS at different meshing locations under the same load and at the same meshing location under different loads, and the contact stress distribution on different meshing teeth and the load distribution among them were studied in a meshing cycle. The analysis results show that the contact stress calculated by the theoretical formula is quite smaller than the actual maximum, and that a power function is discovered between the driving torque and the torsion angle of the worm caused by elastic deformation of contact teeth, which can be used in precise angle control of the worm gear.关键词
