平衡剃齿刀齿厚重磨后,由于分圆弧齿厚的减薄,将破坏刃磨前的平衡啮合角。为了使刃磨后在新的啮合角下与被剃齿数仍能继续保持平衡接触,可通过变更剃齿刀外径而得到补偿。我们知道,剃齿刀外径的改变会导致齿轮剃出的最小曲率半径发生变化,这个变化还要受 Balance shaving tooth thick after grinding, due to the thinning arc tooth thickness, will destroy the pre-sharpening the balance of engagement angle. In order to sharpen the new angle of engagement with the number of shaved teeth can continue to maintain a balance of contact, by changing the outer diameter of shaving cutter to be compensated. We know that a change in the outer diameter of a shaving cutter will result in a change in the minimum radius of curvature of the gear shave,
