摘要
文章在对滚动直线导轨承受负荷时的受力情况进行分析的基础上,研究了预加负荷对钢球刚性的提高,钢球负荷分布状态的改善。不过,过大的预加负荷也会对直线滚动导轨的寿命以及精度均化[1]产生不良的影响。
This thesis is based on the analysis of the Linear Motion Guide under load .It studied the improving effect of preloading on rigidity and the load distribution of balls. However, excessive preloading will have a bad effect on the longevity of linear motion guide and accuracy average effect.
