五轴箱体结构分析与改进

为了解决ZL50型轮式装载机变速器前输出端经常出现的漏油问题,确保变速器质量的稳定,实现装载机产品差异化竞争战略,提高变速器的可靠性,对ZL50型轮式装载机行星动力换挡变速器进行箱体的有限元分析。在装载机变速器处于失速工况下,在Pro/E中建立箱体模型,以Pro/E/mechanica为工具,对箱体各个轴承座进行模拟受力加载,采用适应性P-method技术直接在Pro/E环境下创建有限元模型,模拟了箱体在该工况下的变形,得到了箱体强度和刚度的数值计算结果。着重分析五轴箱体输出端应力、应变及位移响应对密封性能的影响,采取调整箱外筋板分布与内部结构等措施来改善箱体输出端密封性能。分析的结果为变速器的故障诊断提供了参考依据,为该类箱体的设计制造提供了有益的启示。

Structural Analysis and Improvement of a Five Shafts Box

In order to solve the problem of frequent oil leakage on front output end of transmission on a ZL50 wheel loader, ensure the quality stability of transmission, realize difference-making competition strategy of loader products and increase the transmission reliability, finite element analysis is conducted on casing of the planetary power-shift transmission of ZL50 wheel loader.Under a stall condition of loader transmission, the box model is set up in Pro/E.With Pro/E/mechanica as tool, loadings on every bear...
