超声振动辅助珩齿装置的结构设计与振动状态分析

In this paper a structural design of ultrasonic auxiliary gear honing device with interchangeability is made based on constantly improving to the old ones, and the trial device has been made successfully according to the design. While working, the whole ultrasonic oscillation transmission is in state of resonance, and does harmonic oscillation. Proceeding from their oscillation differential equation, meeting the position conditions of borders and jointures between adjacent parts, this paper deducts the amplitude expressions of each part of whole system, and makes the stationary wave chart. The last, by inference, this paper reveals the law that the oscillation trajectory of particles lie in the being machined zone of gear is an ellipse accompanied with perturbations, the perturbations are as a result of actions of reflecting waves coming from various directions.
