Abstract

In order to reach the purpose of improving the gear’s bearing capacity and the quality of transmission. With the NGW31 planetary gear as the research object, by using Romax Designer gear transmission simulation software, the gear original data and the surface contact stress distribution of sun gear and planet gear of the NGW31 planetary gear has been analyzed before gear modification. On this basis, the sun gear and planet gear of the NGW31 planetary gear has been modified. Comparing with the tooth surface contact stress distribution of the sun and planets gear of NGW31 planetary gear to modify front and back, it can be found that sun and planet gear tooth surface contact stress after modification shape is significantly lower than that of before the shape modification, which shows that the gear bearing capacity after modification shape has been improved obviously. The shock is decreased when the gear come into meshing and exited the meshing, the stability of transmission has been improved, achieving the purpose of optimizing to the NGW31 planetary gear
