| 摘 要： | 异形燃气涡轮轴承的外环滚道截面形状为波瓣形，精度要求很高。本文采用的微位移进给驱动机构具有高频响、高精度、大行程，且控制简便的特点。在研究陶瓷结合剂ＣＢＮ砂轮修整及磨削工艺的基础上，采用前馈与速度反馈的控制方法，对工件进行了加工，得到了较好的加工表面质量和滚道轮廓曲线

| Abstract: | For high speed roller bearings used in aircraft engine, the roller's slipping is one of the main causes which result in bearing damage. A kind of new roller bearings having non circular inner race is proved to be a valid method to solve the slipping problem. In this paper, a strategy to grinding the trilobed inner race by using linear motor control technique is presented and illustrated. Practical machining experiment has been made and machining results are satisfactory. |
