3M2180轴承磨床电磁吸盘设计与计算

Design and Calculation of Maganetic Chuck for 3M2180 Bearing Grinder

针对磨削过程中的最大磨削力，对其电磁吸盘所需电磁力进行估算，在此基础上确定电磁吸盘的结构和参数，利用作图法求出结构的实际气隙及对线圈的温升进行计算，最终确定电磁吸盘所需铜线的规格和型号。

The required chucking force of the maganetic chuck is estimated in accordance with the maxium grinding force in grinding. The constructure and the parameters of the maganetic chuck is deternined. The pratical air gap and heat of the coil are calculated by graphics to make the size of coper wire required by the coil of the maganetie chuck.
