摘要
在大功率分流齿轮传动中,各齿轮之间寿命与强度相差较大,导致整个传动系统过早失效,为了改善这种情况、充分发挥各级齿轮传动的潜能,需要对齿轮传动进行等强度优化设计。以功率二分支齿轮传动系统为例,建立了以各齿轮接触安全系数相差最小和弯曲安全系数相差最小为目标的多目标优化设计模型,提出了实现等强度设计的优化方法。算例表明,等强度优化方法不仅可以使齿轮间强度尽可能接近,而且在体积上与最小体积优化设计结果十分接近。
There are large disparity between the gear transmission. To improve this situation, optimal gear life and strength design on equal stress which to premature failure in split - torque intensity of gear transmission is investigated. Take example of dual - path split - torque gear transmission, minimum differentiation between fatigue safety factors of gear is the objective, multi - objective optimization model on equal stress intensity is established. The result manifests that using this design method can make gears have equal gear strength possible, the volume is close to the result of the optimization which aims for minimizing the volume of gear reducer.
