Abstract: The nonlinear static contact analysis is carried out at different positions in the spiral bevel gear transmission process, and the stress variation law of the contact area is obtained; the maximum contact stress is obtained in ANSYS, and the results are compared with the theoretical values. The accuracy of the contact problem is verified by the finite element model method. At the same time, the dynamic contact conditions of this kind of gears at different meshing moments are analyzed, and the speed influence on the contact characte-ristics is compared. Determine whether the contact strength of the spiral bevel gear meets the requirements by comparing the change law of contact stress at different static and dynamic angles.
