毕业设计（论文）外文参考文献翻译 机械工程 系（院） 20 08 届 题 目（中文） 电主轴的机械设计 （英文）the mechanic designs of electric spindles 学生姓名 专业班 完成日期： 2008 年 3月 23 日 目 录 电主轴技术水平分析………………………………………………（8） 高速电主轴单元…………………………………………………（14） The electrical technical level of main shaft is analysed Abstract: Electrical main shaft is the processing machine tool of numerical control heart parts , this paper has introduced typical structure and the working principle of electrical main shaft , has elaborated the crucial technology of electrical main shaft , has summarized it to develop tendency. Keyword: The electrical porcelain ball of main shaft mix the bearing lubrication of oil gas 1, it is general to state the processing quality that can not only raise processing efficiency substantially because of high speed processing and can still raise workpiece apparently, so, its application field is very extensive , is especially in aerospace , the manufacturing industries such as automobile and mould in. It is spoilt recently that so, the machine tool of numerical control that has high speed process capability has become market. Now, the domestic and international each famous manufacturer of machine tool adopts the electrical structure of main shaft extensively in the machine tool of numerical control , is especially being compound to process machine tool and much axle to unite to move , polyhedron processing machine tool and the machine tool of parallel connection in. Electrical main shaft is the processing machine tool of numerical control heart parts , its performance index direct decision the level of machine tool, it is that machine tool realizes basic condition and the prerequisite of high speed processing. 2 the working principle electrical main shaft of the working principle, typical structure and 2.1 advantage electrical main shafts of electrical main shaft is the direct motor rotor of be hollow pack in main sha
