| 摘 要： | 该文提出了一种减小滚珠丝杠副摩擦力的超声振动减摩振子。将激振器与滚珠丝杠的螺母通过螺栓在法兰处相连,通过激发减摩振子的二阶扭转振动模态,实现对滚珠丝杠副的减摩。利用有限元分析软件对减摩振子进行模态分析并对激振器套筒长度、激振器法兰厚度及内孔直径进行正交试验,通过优选得到最佳组合并确定其主要结构尺寸,试制了样件。最后对减摩振子进行实验测试,验证了该减摩方法的可行性。

| Abstract: | In this paper, an ultrasonic anti-friction vibrator is proposed to reduce the friction of ball screw pair. The vibration exciter and the nut of ball screw pair are connected at the flange by bolts, and the friction reduction of the ball screw pair is realized by exciting the first torsional vibration mode of the anti-friction vibrator. The modal analysis of the anti-friction vibrator is carried out using the finite element method. The orthogonal experiment on the sleeve length of the exciter, the thickness of the exciter flange and inner diameter is carried out. The best combination is obtained, and the size of the main structure is determined. A prototype is fabricated. Finally, the feasibility of the antifriction method is verified by the experiment on the prototype of the anti-friction vibrator. |
