Abstract：Aiming at the problem that there is no dynamic analysis of the roller pushing process during the measurement of cylindrical roller dimensions， the model of the cylindrical roller push process is established based on the working principle of the cylindrical roller push process， dynamic analysis of cylindrical roller push model is carried out， and the calculation equation of the time required for the cylindrical roller from sliding to pure rolling is obtained by analyzing the model， and the factors affecting the time required for the roller to reach pure rolling state are found. When the specification model of cylindrical roller is determined， the dynamic simulation of cylindrical roller push process is carried out to verify the dynamic analysis of cylindrical roller push process is effective and to understand the motion law of cylindrical roller push process. The research results can be used in parametric design of cylindrical roller push system， and the research provides a theoretical basis and technical support for column class work-piece push system center on cylindrical rollers.

隨着国家工业的快速发展，精密轴承在工业生产中的应用越来越广泛[1-4]。圆柱滚子作为精密圆柱滚子轴承的核心零件，其尺寸制造误差过大会使精密圆柱滚子轴承运行过程中产生大幅度的振动和温升，严重影响着精密轴承的使用寿命[5-10]。为了消除圆柱滚子出厂时尺寸误差对精密轴承寿命和运转稳定性的影响，必须对圆柱滚子的出厂尺寸进行精密测量。目前，圆柱滚子尺寸测量的主要方法是通过压力传感器与圆柱滚子之间的接触力判断圆柱滚子尺寸误差，从而测得圆柱滚子的直径和长度，这种测量方法的准确性受到圆柱滚子与传感器触头接触时的运动状态影响，若圆柱滚子以匀速状态通过传感器触头，可有效降低测量误差[11]。……
