摘　　要：采用内啮合强力珩齿工艺加工工件,通常需要用与工件相对应的定制金刚石修整轮对珩磨轮进行修整。为了增加金刚石修整轮的通用性,降低内啮合强力珩齿工艺的成本,提出了一种基于珩磨轮柔性修整的内啮合强力珩齿修形方法。首先,根据珩齿机各轴运动关系,建立珩磨轮修整和工件珩削的齿面数学模型;然后,将珩磨轮修整时机床的多轴联动以多项式形式表示,将各轴运动对最终工件齿面的影响表示为敏感度矩阵,以修形齿面为目标优化各轴多项式系数;最后,根据优化后的机床运动参数计算最终工件齿面,对所得工件进行齿面接触分析。结果表明,该工艺方法可以实现采用标准金刚石修整轮对珩磨轮进行柔性修整,最终加工出有效的修形齿轮工件。In order to process the workpiece with internal gearing power honing technology,the honing wheel is usually dressed with the customized diamond dressing wheel corresponding to the workpiece.A method of internal gearing power honing modification based on flexible dressing of honing wheel is proposed to increase the commonality of diamond dressing wheel,reduce the cost of internal gearing power honing technology.Firstly,the tooth surface mathematical model of dressing and honing is established according to the motion relationship of each axis of gear honing machine.Then,the multi axis linkage of honing wheel dressing is expressed in polynomial form,the influence of each axis movement on the final workpiece tooth surface is expressed as sensitivity matrix,and the polynomial coefficients of each axis are optimized with the target modification tooth surface.Finally,the final tooth surface of the workpiece is calculated according to the optimized motion parameters of honing,and the tooth contact is analyzed.The results show the standard diamond dressing wheel can be used for flexible dressing of honing wheel,and the effective modification workpiece can be machined finally.
