TSXCTY2A

TSXCTY2A 分析结果表明输入级齿轮在75%驱动模式、100%驱动模式和100%滑行模式下齿轮错位量分别优于目标值12 μm、2 μm和10 μm。在所有正驱工况下输出级齿轮错位量都很小，滑行模式下错位量略大，但在100%滑行模式下依然优于目标值7 μm。基于MASTA软件的错位量分析结果可知，输入和输出级齿轮错位量在常用的低扭矩驱动模式和滑行模式下表现良好。

4 齿轮啮合斑点分析  

综合修形后各工况负荷下都较好地实现了全齿面接触，有效避免了边缘和齿顶受到负荷造成的应力集中，齿面负荷的分布较合理，表明该修形参数下的齿轮接触斑点位置及大小是可以接受的。

5 齿轮传动误差仿真分析  

输入级、输出级齿轮修形后的传动误差仿真结果如图8、图9所示。

通过对输入级齿轮修形的传动误差分析可以看到：

(1) 在正驱和滑行工况下峰-峰TE都很小。峰TE发生在50%驱动模式和50%滑行模式，分别为0.71 μm和0.66 μm，结果优于EV减速器要求的目标值。

(2) 峰-峰TE可以分解到成分谐波(图8显示的前三阶谐波)中。在所有工况下，TE的主要贡献是一阶谐波并随着谐波数目的增加而呈指数衰减。
