The limit pressure angle is related to such factors as offset angle, mean spiral angle, pitch cone angle and mean pitch cone diameter, not to geometrical shape of the tooth surface.
极限压力角受偏置角、大小轮的螺旋角、节锥角和中点的分度圆直径影响，而与齿面的其他参数无关等结论。
The paper analyses the effect of translation and offset angle of the cone axis to shaft one on the gap variation between two ring-button, which position on two cones.
分析了牙轮钻头安装和磨损间隙引起牙轮相对牙爪轴线的平移和倾斜对相邻锥体上球齿间隙的影响，通过计算，当牙轮、牙爪轴线轴向、径向平移使球齿的趋近量有抵消的趋势；
