摘要
相对于传统的加工方法,超声研齿加工具有较高的效率和较好的齿面质量。依据一维波动理论,设计了一种普通变幅杆和带轴的锥齿轮组合形成的复合变幅杆,使其达到所需的谐振频率。然后通过有限元的方法对所设计的复合变幅杆与所选用的换能器组成的超声研齿系统进行分析,验证了理论设计方法的正确性。并在此超声研齿系统的基础上,从带轴的锥齿轮的结构出发,分析了锥齿轮部分结构参数的变化对轴齿轮超声研齿系统的谐振频率和振幅的影响规律,为轴齿轮超声加工系统的设计提供了依据。
Ultrasonic gear lapping has the special advantages of higher efficiency and better tooth surface quality than the traditional processing methods. Based on one dimensional wave theory, this paper designed a composite horn which is formed by the combination of an ordinary horn and a bevel gear with shaft, and the composite horn can get the resonant frequency which is needed. Ultrasonic lapping system which is formed by this composite horn and transducer was analyzed by the finite-element method. Based on the ultrasonic lapping system, the effect changing structural parameters of bevel gear with shaft on the resonant frequency and amplitude of the ultrasonic vibration system is analyzed. And a basis for the design of ultrasonic machining system of the gear shaft was provided.
