四、刀盘設計和調整計算的一般公式1、计算的共通原则如图12的右上角所示,为了在齿面上形成局部接触,轮齿凹面计算点的曲率半径р凹应大于凸面的曲率半径р凸。这一要求可通将外刀的切线半径增大Δrь,内刀的切线半径减小Δrь来实现。但是,由图12可 Fourth, the general design and adjustment of the cutter 1, the common principle of calculation shown in Figure 12, the upper right corner, in order to form local contact on the tooth surface, Z radius convex. This requirement can be achieved by increasing the tangent radius of the outer knife by Δrь and by reducing the tangent radius of the inner knife by Δrь. However, from Figure 12 can
