Abstract

By the contact analysis of the traction gears with shafts of high-speed and heavy-load locomotive, the deformation and load distribution of the Front Guide Surface in starting operation are obtained. According the results, the ideal longitudinal modification curve is fitted out. The gear parametric models were completed, and the load distribution and the contact stress of the gears are compared before and after tooth longitudinal modification in ANSYS. It shows the modification methods and the amount of the modification are reasonable.
