At same time we analysed the necessary of reaming after pressing - bushed and found out the deformed law in the hole through a lot of testing 同时分析了压套后铰孔的必要性，经大量试验摸清了套内孔变形规律，确定了预留铰孔量。

Abstract : the factors to influence fatigue life of chain plate areconcluded by experimental methods . the factors to prolong life of chain plate are analyzed by theoretical methods . the maximum value of crushing hole in 16a roller chain plate is calculated by finite element method 文摘:用试验方法确定了挤孔对链板疲劳寿命的影响，从理论上分析了在最佳挤孔量下，链板疲劳寿命提高的因素，用有限元法计算了16a链板的最佳挤孔量，并与试验结果进行了比较。
