摘要
随着高精技术的的发展，所生产的零件越来越精密，无论是对尺寸公差还是装配公差都要求得越来越高，因此毋庸置疑对机床的要求也愈发严格。高速电主轴是高精加工机床的重要组成部件，在生产中不仅能直接影响机床生产零件的误差，而且还会在运行过程中产生热量造成主轴的热变形而间接引起生产过程中的尺寸误差，所以对电主轴的误差控制成为了必然的趋势。本课题主要是通过SolidWorks建立磨齿机电主轴模型导入有限元软件进行仿真模拟其热态特性，通过计算分析高速电主轴的稳态温度场和变形为控制电主轴在运行过程中产生的热变形和热误差补偿做理论和实验支撑。
关键词:高速电主轴稳态温度场热变形热特性
ABSTRACT
With the development of high-precision technology, the parts produced are becoming more and more sophisticated, both in terms of dimensional tolerances and assembly tolerances are more and more demanding, so there is no doubt that the requirements of machine tools are becoming more stringent. High-speed electric spindle is an important component of high finishing machine tools, in the production can not only directly affect the error of machine tool production parts, but also in the process of running heat caused by thermal deformation of the spindle and indirectly caused by the dimensional error in the production process, so the error control of the electric spindle has become an inevitable trend. This topic is mainly through the establishment of gear grinding electromechanical spindle model imported into the finite element software simulation of its thermal characteristics, through the calculation and analysis of high-speed electric spindle steady temperature field and deformation for the control of the electric spindle in the operation of the thermal deformation and thermal error compensation to do theoretical and experimental support.
