摘　　要：在新型干法水泥生产工艺中,回转窑是烧成工段的核心设备。课题组通过对某型号回转窑传动齿轮进行计算分析,得到轮齿啮合变形量随齿廓的分布曲线、轮齿啮合所受最大应力的大小及位置,并与数值模拟结果保持一致。在动态分析的基础上,通过nCode Design-Life软件对传动齿轮进行疲劳特性分析,得到寿命云图及疲劳危险点位置,为回转窑传动齿轮的进一步优化及生产维护提供了理论参考。In the new dry cement production process,the rotary kiln is the core equipment of the firing section.The research group calculated and analyzed the transmission gear of a certain type of rotary kiln,and obtained the distribution curve of tooth meshing deformation with tooth profile,as well as the magnitude and position of the maximum stress on tooth meshing,which were consistent with the numerical simulation results.On the basis of dynamic analysis,fatigue characteristics of transmission gear were analyzed by nCode-DesignLife,and life cloud map and fatigue danger point location were obtained,which provided theoretical reference for further optimization and production maintenance of rotary kiln transmission gear.
