Research on Meshing Impact of Escalator Step Chain Roller with Drive Sprocket

针对自动扶梯运行过程中梯级滚轮与驱动链轮的啮合冲击,根据链传动运动学原理,在RecurDyn里建立了自动扶梯梯级链传动系统的虚拟样机模型,并进行动力学仿真。对梯级滚轮与主驱动轮齿啮合瞬间的冲击载荷规律和分布情况进行了分析,同时通过实验测量啮合过程中滚轮的最大接触应力,并与计算结果进行了比较。

Based on MBD simulation method,built the virtual prototype of escalator step chain system and simulate the movement of the chain process with RecurDyn chain tools,multi-analysis the contact force between step chain roller and sprocket wheel during meshing impaction.Compare the maximum contact stress value from measurement experiment with theoretical calculation.
