| 摘 要： | 利用有限元与实验研究了一种变速器五挡齿轮的小轮根部带有油孔的齿根弯曲应力的问题.利用三维Pro/E和Pro/Mechanica软件,对该变速箱中的五挡齿轮对建立了多齿对同时空间接触的物理力学模型,并进行了每隔2°来分析各个接触瞬间的齿根弯曲应力以及油孔周围应力的分布情况.在一个完整的啮合过程中,得出有油孔齿轮的齿根部第一主应力最大值比无油孔齿轮的齿根部第一主应力最大值增大了13.68％的结论.从齿轮的弯曲疲劳破坏形式与特点来看,仿真结果与实验结果一致.

| Abstract: | By FEA and experiment,bending stress of pinion with tooth root oilhole for speed changer five-speed gears is studied.Using the three-dimensional software Pro/e and Pro/Mechanica,and based on the analysis of the five-speed gears,physical and mechanical model of several pairs tooth contact are built and analyze the distribution of bending stress and the stress around oil hole by each 2° rotation at each contacting moment are analyzed.Finally,through the whole simulation of gear meshing,it can be concluded that the maximum bending stress of the pinion with oilhole is increased by 13.68%,compared with the pinion without oilhole.In point of the form and characteristic of the gear bending fatigue damage,the above result is the same with experimental results. |
