摘要

全面考虑箱体、轴承、轴的变形及装配间隙等影响因素,采用有限元法对机车牵引齿轮接触状态、载荷分布趋势进行分析。依据啮合过程中出现的偏载现象,采用遗传算法优化获得最佳齿向圆弧修形曲线;再通过对修形前、后机车齿轮正、反转两种啮合状态的对比分析,得知修形后轮齿齿宽方向上载荷分布更加均匀,偏载造成的应力集中现象得到明显改善,接触应力、弯曲应力最大值均减小,优化得到的修形曲线效果较好。

Abstract

Considering the factors such as the deformation of the box body,the bearing and the shaft and the assembling clearance,the finite element method is used to analyze the contact state and load distribution of the traction gear. According to partial load in the meshing process,the optimum gear profile modification curve is optimized by using genetic algorithm. Through the comparison and analysis of the two meshing states of the forward and reversal of the locomotive gear,it can be found the load distribution on the teeth is more uniform,the stress concentration phenomenon caused by partial load is improved,and the maximum value of contact stress and bending stress significantly is reduced. The result shows the modification curve has a good effect.
