Based on the fact of driven gear moving prior to normal locality when driving gear pair moving from upper dead center to lower dead center , considering all influential elements , the maximum backlash of gear pair can be controlled to satisfy the special driving requirement through controlling the length and deviation of its common normal without increasing its manufacture precision 摘要根據換向傳動齒輪副從上止點向下止點運動時被動齒輪運動超前的實際,從影響齒輪副側隙的各種因素出發,在不提高齒輪副制造精度的前提下,通過拉制齒輪副公法線長度及其偏差從而有效地控制齒輪副的最大齒側間隙,以滿足傳動的特殊要求。
