Abstract: Based on the finite element method, a parametric model generation method of spur gears in meshing process is presented. The finite element models of spur gears have been established, in which the contact range and the whole finite element model can be automatically adjusted with the change of meshing process. The load distribution between the meshing teeth pair, contact force distribution on the contact surface and stress distribution of the model are investigated in meshing process by using the finite element elastic contact analysis method. The researches developed can be used in load and stress of spur gears computer simulation in meshing process.
