基于有限元法的汽车变速器齿轮与轴承优化

Optimization of Gears and Bearings in Vehicle Transmissions by Means of FEM

采埃孚集团开发和生产了种类繁多的传动齿轮。对于齿轮的优化和可靠设计,有限元法是尤为适合的。而且,这种方法能容易集成于采埃孚的程序系统。本文展示了在开发过程中如何运用该方法进行齿轮优化。此外,文中多处演示了齿轮和轴承之间的相互作用。这也是采埃孚集团致力于开发轴承计算的原因。文中实例展现了如何优化滚动轴承以达到理想的齿轮接触印痕。当然,这些优化方法也适用于传动齿轮。

A large variety of gearings are developed and manufactured by the ZF Group. FEM is especially suitable for optimal, reliable gearing development. It can also easily be integrated into the ZF program landscape. This paper shows how the method can be used in the development process to optimize gearings. However, once again the strong interaction between gearing and bearing is repeatedly demonstrated. That is why ZF has also invested in the development of bearing calculations. We give an example of how rolling bearings can also be optimized for an ideal gearing contact pattern. Naturally, the methods can also be applied to running gears.
