Geometric Analysis of Normal Backlash Spacing for External Shifted Gear Driving

通过几何分析的方法 ,导出外啮合渐开线变位齿轮传动中心距略变大时 ,法向齿侧间隙的计算公式 ,并以实例分析了对法向齿侧间隙的影响程度 ,导出了法向齿侧隙与啮合角及变位系数之间的关系式 。

A computing formula of normal backtash is derived for profile shifted gear driving by centre distance changing bigger. Its influence guantity to normal backlash is analysed by example. The relation of normal backlash, pressure angle and deflection coefficient for designers reference are derived.
