采用“非零”变位原理设计等高齿曲齿锥齿轮，克服了传统设计方法中的许多限制条件，能够实现传统的设计方法所不能实现的传动要求。理论分析说明：运用“非零”变位原理，在Ｏｅｒｌｉｋｏｎ齿形制上应用，以求在同材质、同精度、同尺寸条件下，从设计上提高抗磨损性能和抗点蚀能力。 Adopting the principle of “non-zero” displacement to design contour tooth bevel gear, it overcomes many limitations in the traditional design method, and can meet the requirements of transmission that traditional design methods can not achieve. The theoretical analysis shows that the “non-zero” displacement principle is applied to the Oerlikon tooth profile system to improve the wear resistance and pitting resistance under the same material quality, same precision and same size.
