| 摘 要： | 以轴承内圈为研究对象,对超高速离心磨削加工过程中电磁无心夹具的磁极、定位形式、偏心象限进行分析和选择,结果表明:当定位形式是以工件外圆定位时,偏心量位于第一或第二象限加工效果最好;同时对摩擦合力进行分析,得出了摩擦合力的计算公式,根据公式计算了工件电主轴的功率,为电主轴的选型提供了理论方法。研究结果为电磁无心夹具的设计与安装提供了参考。

Applications of Electromagnetic Coreless Fixture in Ultra-high-speed Centrifugal Grinding |
| |
| Abstract: | The magnetic pole , location mode , eccentric quadrant of electromagnetic coreless fixture during the process of ultra -high-speed centrifugal grinding were chosen with the analyses of bearing ring .The result shows that if it is orientated by outer circle of workpiece itself , the processing effect is the best when the eccentricity is in the first or second quadrant .The computational formulas of resultant force of friction was obtained after analysing .The power of motorzed spindle was figured out based on these formulas , which provide a theoretical method for selection of motorized spindle .The results provide reference for design and installation of electromag-netic coreless fixture . |
