Abstract
The mashing properties of the mismatched gear pair and the pre-control of contact mark of tooth surface have been researched in this paper, while the elastic deformation of tooth surface was taken into consideration. The theory of contact stress has been combined with the theories of spatial gear meshing. A new way and new method to control the quality of engagement of the spiral bevel gears and the Hypoid gears have been presented in this paper. For this purpose, the Baxter method, with which the conjugate curvature of line contact meshing can be calculated, has been extended into the case of spatial meshing of point contact.
