摘要
针对HXD1B型机车驱动单元中的齿轮毂强度不足,可靠性不佳的问题进行研究,从结构设计、热处理工艺等方面进行优化设计,并对优化后的齿轮毂进行有限元分析。得出的研究结果表明,优化后的齿轮毂具有良好的机械性能并很好的改善了应力集中现象。经过装车验证,满足机车驱动单元的使用要求。
In order to solve the problem of insufficient strength and poor reliability of the gear hub in the drive unit of HXD1B electric locomotive,the optimization design of the gear hub was carried out from the aspects of structural,heat treatment process.The finite element analysis method was applied for the optimized gear hub.The results show that the optimized gear hub has good mechanical performance and the stress concentration has been improved.After assembling to electric locomotive,the optimized gear hub meets the use requirements of the locomotive drive unit.
