摘要
针对某微车高速空挡滑行工况下主减速器振动异响大的问题,以主减速器准双曲面齿轮压力角为研究对象。建立了齿轮系统扭转振动动力学模型,改变UG模型中轮齿两侧压力角,导入到ADAMS后对比分析该工况下不同压力角时齿轮系统的动态特性,得出被动轮轮齿凸面压力角减小1°、同时凹面压力角增大1°时可改善主减速器齿轮系统啮合振动性能。最后采用试验验证了仿真分析的正确性,可应用于主减速器齿轮的设计和制造。
For the severe vibration and scream noise of a mini car main reducer in high- speed neutral coasting condition,the pressure angle of the main reducer hypoid gears is taken as the study object. A torsional vibration dynamics model of gears system is established,after changing the pressure angle on both sides of gear tooth in the UG model and importing into the ADMAS,the dynamics characteristics of the gear system with different pressure angle under the same coasting condition are studied and compared. It is concluded that the meshing vibration performance of main reducer gears system could be improved when the convex surface pressure angle of the passive gear tooth decreased 1° at the same time the concave surface pressure angle of the passive gear tooth increased 1°. The correctness of the simulation analysis is verified by experiments at last,and the research result could be applied to the design and manufacture of the main reducer gear.
