在对国内外机车牵引齿轮现状进行深入调研的基础上，提出了从优选材料及热处理工艺、进行齿形和参数优化设计、合理选择制造精度与工艺、优选润滑剂与润滑密封方式，改善动力学性能等五个方面提高我国准高速机车牵引齿轮传动承载能力和寿命的具体措施，其中在齿形和参数优化方面，设计了优选刀具角并能使齿根危险断面齿厚尽可能大，而应力集中尽可能小的磨前滚刀，优选出能使在啮合过程中最大闪温值为最小的变位系数，最后用有限元法计算了轮齿的变形与应力，并在此基础上考虑机车启动，持续与高速运行三种工况对轮齿进行齿廓与齿向的优化修形设计。
Based on the investigation of the current situation of locomotive traction gears both at home and abroad, the optimization of tooth profile and parameters, the selection of manufacturing precision and technology, the optimization of lubricants and lubrication, the improvement of kinetics Performance and other five aspects to improve China’s quasi-high-speed locomotive traction gear drive carrying capacity and life-specific measures, including tooth profile and parameter optimization, the design of the preferred cutter angle and tooth root can make the tooth section as thick as possible, while the stress Focus on the smallest possible hob before hobbing, select the best to make in the process of maximum flash temperature value of the minimum coefficient of deformation, and finally calculated by finite element method of gear tooth deformation and stress, and on this basis to consider the locomotive Optimized design of tooth profile and tooth profile for three conditions of starting, continuous and high-speed running.
