机车牵引齿轮静动态分析及在东风4D客运机车中的应用

Static and Dynamic Analysis of Locomotive Driven Gear and Its Application in DF - 4D Locomotive

以东风４Ｄ客运机车牵引从动齿轮为例，依据齿轮加工刀具参数及其它有关参数，基于齿轮啮合原理自编软件，自动绘制了机车牵引齿轮的齿形，用Ｉ－ＤＥＡＳ软件对该齿轮进行了静动态分析，不仅获得了各种工况下齿轮受力时轮齿部分的应力及变形，也获得了时变外载作用下的动力响应，为设计提供了有价值的计算结果．

By using a software developed by current authors, DF-4D passenger locomotive driven gear is automatically drawn based on machine tool parameters and tooth profile of the gear. Static and dynamic force analysis of the gear is conducted by I-deas. Stress and deformation of the gear at various load conditions dynamical response is calculated. Some useful results are provided to the designers as well.
