1.机床参数的确定：
1 运动参数： 回转主运动的机床，主运动的参数是主轴转速。
最低转速和最高转速： 12.5rpm 2120rpm
分级变速时的主轴转速数列：机床的分级变速机构共有Z级。Z 12， 。任意两级转速之间的关系应为：
据 φ11，得：φ 1.58。查表得：各轴转速：12.5、20、31.5、50、80、125、200、315、500、800、1250、2120。
2 动力参数的确定：由任务书设定电动机功率：N 1.5KW。查表得应该选择Y系列三相异步电动机Y90L-4（同步转速1500r/min，50HZ，380V），转速1420rpm，效率81%。功率因素cosφ 0.82，额定转矩2.3KNm。
2.运动设计：
2.1 传动组的传动副数的确定： 传动组和传动副数可能的方案有： 12 4*3 12 3*4 12 3*2*2 12 2*3*2 12 2*2*3 在上列各方案中，前两个有时可以省掉一根轴。缺点是有一个传动组内有四个传动副。如果用一个四联滑移齿轮，则会增加轴向尺寸；如果用两
