齿轮的精加工——金刚石电化学法

讨论了金刚石电化学精加工齿轮的原理、工艺参数及实验装置。分析了电解和机械磨削中用微磨削方法和电化学方法去除金属的速度,两者取速度比最大值时,则有利于达到很高的加工精度。提出了齿轮纵向误差产生的动力学方程,得出径向跳动、齿向误差与加工时间的关系。最后通过实验,证明了金刚石电化学加工时精度的提高是显著的,且金刚石阴极耐磨性高,能够根据工件形状尺寸及加工间隙的分布规律来设计。

Diamond electrical——chemistry method for gear finishing machining

The principle,the technique parameters and the experimental equipment of the diamond electrical-chemistry method for gear finishing machining is discussed here.The speed to remove the metal,with both the micro-attrition(used in electrolyse and mechanical attrition)and electrical-chemistry method,is worked out that high machining precision can be obtained when the speed rate between them are maximum.According to the dynamics kinetics equation on the gear's vertical error,the radial jump and relationship between the error and processing time are offered also.At last,the precision improvement is verified with an example.It shows that negative end of the diamond is with high anti-attrition ability and can be designed according to the workpiece shape and the clearance distribution.
