摘要
非正交航空弧齿锥齿轮由于其高速重载服役特性,齿面磨削精度要求高,很难实现实际齿面与理论齿面的匹配。为了满足高效率高精度要求,本文提出了一种齿面精度自适应加工参数驱动控制方法。首先,基于先进的全工序法磨削仿真,进行加工参数驱动的齿面精确数学建模。然后,以磨削精度为控制目标,建立齿面误差测量、齿面设计,齿面误差反调集成的加工精度自适应控制模型。最后,通过齿面误差敏感性分析策略和改进Levenberg-Marquardt算法,实现预设目标齿面的自适应逼近,求解最终精确机床加工参数。本文提供的算例证明了该方法有效性。
In consideration of high speed and heavy load operation characteristics of non-orthogonal aerospace spiral bevel gears and high tooth flank grinding accuracy,it is very difficult to achieve the matching of the actual tooth surface and the theoretical tooth surface.For satisfying the high accuracy and efficiency,an adaptive machine settings driven tooth flank accuracy control is proposed.Firstly,with simulation of advanced free-form grinding,machine settings driven tooth flank mathematical modeling is performed.Then,for tooth flank grinding accuracy control,adaptive grinding accuracy control model is established by correlating with the tooth flank form error measurement,tooth flank design and tooth flank form error modification.Finally,with applications of tooth flank form error sensitivity analysis strategy and the improved Levenberg-Marquardt algorithm,the adaptive approximation of the preset target tooth surface is achieved,and the final precise machine tool machining parameters are solved.Given numerical instance in this work can verify the validation of the proposed method.
