本文介绍了无因次齿轮轮齿的概念,用以使齿轮应力为最小的问题。与现有的其他方法比较,本质上减少了许多设计变量,所推荐的模型方法明显缩短了计算时间。代替承载齿轮轮齿模型和运行BEA在各个优化过程的迭代阶段去计算最大的齿根应力,该应力用表值插入法来计算。计算前采用BEM对无因次模型相应于不同的设计参数的组合。与传递相同转矩的标准齿轮的应力相比较,对优化方法和最佳齿根应力采用了复杂的算法。在这种方法内,可降低应力超过36.5%。该应力的降低,已经用两维光弹试验证实。
This article describes the concept of dimensionless gear teeth to minimize gear stress. Compared with other existing methods, many design variables are reduced in essence, and the proposed model method obviously shortens the calculation time. Instead of carrying the gear tooth model and running BEA, the maximum root stress is calculated during the iteration of each optimization process, which is calculated using the table insertion method. The BEM for calculation before the dimensionless model corresponds to a combination of different design parameters. Comparing with the stress of the standard gear that transmits the same torque, a complicated algorithm is used for the optimization method and the optimal root stress. Within this method, stress can be reduced by more than 36.5%. This reduction in stress has been confirmed by a two-dimensional photoelastic test.
