| 摘 要： | 通过分析数控磨床进给滚珠丝杠刚度的影响因素，提出了选用滚动体数目多且增大接触角的大刚度丝杠专用轴承；应用大直径螺栓并严控制其伸出长度；预紧螺母预紧力约为最大轴向载荷的1／3等改进磨床进给伺服机构性能的建议。

| Abstract: | The effect factors on feeding rolling ball screw rigidity of NC grinder is analyzed.Some suggestions are put forward in order to improve performance of servo mechanism of grinder feeding,such as selecting special ball feed screw bearing with high rigidity,utilizing more rolling element number and bigger contact angular in bearings,using large diameter bolt to control protruding length,preload force of preload nut being about 1/3 of the maximum axial load. |
