摘　　要：以某款电动汽车减速器为例,对比标准齿和细高齿2种齿轮参数方案,分析细高齿对齿轮强度和传动误差的影响。经过研究可知,细高齿重合度大、传动误差小,不仅可以达到降低减速器齿轮啮合噪声的目的,而且能够提高齿轮的承载能力。针对细高齿进行修形优化,降低其传动误差波动,改善齿面接触斑偏载现象,进一步改善齿轮啮合质量,降低减速器运行噪声。Taking a gearbox of an electric vehicle as an example,this paper analyzes the influence of high tooth gear on gear strength and transmission error by comparing two gear parameter schemes of standard tooth and high tooth gear.The results show that the gear meshing noise can be reduced and the bearing capacity can be improved.The high tooth gear are modified and optimized to reduce the transmission error fluctuation,improve the unbalance load of tooth surface contact area,further improve the gear meshing quality and reduce the running noise.
