摘　　要：轴承作为传动轴的关键支撑零部件,在多载荷、多工况下,轴承寿命的正确评估成为工程机械传动系统设计过程中的重要环节。文中以一工程机械多轴传动系统为研究对象,在9种工况挡位下,运用Romax软件建立传动系统的虚拟样机,通过ISO轴承寿命计算法和轴承修正寿命计算法对轴承寿命仿真计算,由模拟数据评估轴承的使用寿命,为传动系统设计过程中的轴承选型设计和寿命分析提供参考。Bearing is a key component under multi-load and multi-condition, correct assessment of the bearing life is an important part in the transmission design process for engineering machinery. This paper studies a multi-shaft transmission system in engineering machinery. Under nine kinds of working conditions, Romax software is used to build virtual prototype of the multi-shaft transmission system. The bearing life is calculated by ISO and improved bearing life calculation method.Simulation data is used to evaluate the bearing life, which provides a reference for the bearing selection and life analysis in the design process.
