摘要

以齿轮传动分析软件Romax 为建模平台，借助三维软件Inventor 和有限元前处理软件Hypermesh，建立了包含柔性车轴和柔性箱体在内的隧道牵引机车用车轴齿轮箱的刚柔耦合模型。在综合考虑柔性体变形、轴承间隙和齿轮啮合错位的基础上，依据载荷谱进行了齿轮修形设计、齿轮疲劳强度、轴承寿命和箱体静强度及模态的校核计算。计算结果和实际运行情况表明，该刚柔耦合模型用于车轴齿轮箱的设计开发是可行的。

Abstract

The rigid-flexible coupling model of axle gear case in tunnel traction locomotive which included the flexible axle and case body was established using Romax, Inventor and Hypermesh software. Tooth profile modification, gear-tooth fatigue strength, bearing life, and the static strength and modal of case body were calculated and analyzed by applying load spectrum to the rigid-flexible coupling model, in which the effects of the flexible deflection, bearing clearance and misalignments were detected and considered. The calculation results and actual practice showed that the rigid-flexible coupling model of axle gear case could be used for developing the product in the design work.
