| Summary: | The contact path and transmission error are key indexes for evaluating the meshing performance of spiral bevel gears. The contact path is offset by misalignment，and symmetry and fluctuation amplitude of transmission error change. Therefore，based on installation adjustment，an optimization method for the contact path and transmission error of spiral bevel gears is proposed. The equations are established by the constraining assembly conditions and the initial transmission ratio，and then the theoretical installation adjustment is solved. A tooth contact analysis （TCA） algorithm with the misalignment is built by introducing gear pair misalignment. Taking the misalignment as the design variable and presetting the characteristic parameters of contact path and the transmission error，an objective function is built and solved by the nonlinear optimization algorithm. The optimization results show that the contact path is moved to the small end and the loaded contact area is expanded to the middle of the tooth flank，load bearing contact performance is improved. That the droop deviation and fluctuation amplitude of the transmission error curve are decreased，whichis beneficial to avoid edge contact and improve dynamic performance. |
