滚珠丝杠支承端的结构改进设计

Improved design of ball screw support end structure

通过对原有数控机床滚珠丝杠支承端轴承易损坏的现象总结分析,找出造成数控机床定位精度不稳定及滚珠丝杠支撑端个别轴承损坏的主要原因,提出了滚珠丝杠传动支撑端结构改进设计方案和应采取的措施。通过设计改进后实际测试结果验证了改进的效果,将改进的结构成功应用于多种同类型数控机床的滚珠丝杠传动中,提高了滚珠丝杠传动的可靠性,保证了数控机床定位精度的稳定。

By analyzing damage phenomenon of the original ball screw support end bearing,find out the main cause of the positioning accuracy of CNC machine tools which is not stable and the main reason of individual bearing damage of the ball screw support end,propose the improved design scheme and measures to be taken of the ball screw drive support end structure,by improving the design to verify the actual effect of the improved design scheme,it is successfully applied to a variety of the same type of CNC machine tools,improve the reliability of the ball screw drive,ensure the stability of CNC machine tool accuracy.
