精密滚珠丝杆对导轨要求都有哪些?

来源:http://www.jngongrun.com/ 日期:2021-08-16 发布人:admin

精 密滚珠丝杆主要作用是支撑直线运动,使得直线运动较为准确且能够在高速情况下依然保持直线运动的这么一个传动元件。其本身的导轨要求也就较高,只有导轨能够提供准确有用的途径,才能够保其做的直线运动有效且是有用的。精密滚珠丝杆对导轨要求具体是这样的。

The main function of precision ball screw is to support the linear motion, which makes the linear motion more accurate and can still maintain the linear motion at high speed. Its own guide rail has high requirements. Only when the guide rail can provide an accurate and useful way can it ensure that its linear motion is effective and useful. The requirements of precision ball screw for guide rail are as follows.
1、导向的精度要求
1. Accuracy requirements for guidance
导轨支持运动做直线运动还是做带有圆度的运动,而影响到导向精度的是导轨的几何精度还有结构形式。当然了导轨的热变形也在一定程度上影响到了精度,还有工作时候可能碰到的特殊情况,比如说是油膜的厚度。
The guide rail supports linear motion or motion with roundness, and what affects the guiding accuracy is the geometric accuracy and structural form of the guide rail. Of course, the thermal deformation of the guide rail also affects the accuracy to a certain extent, and there are special situations that may be encountered during work, such as the thickness of the oil film.

2、耐磨
2. Wear resistance
反复的直线运动,要求导轨的耐磨性要较高,否直线运动的时间一长,导轨本身的精度就已经降低了,那么滚珠丝杆的直线运动的稳定性也就受到了影响。
Repeated linear motion requires high wear resistance of the guide rail. If the linear motion takes a long time, the accuracy of the guide rail itself has been reduced, and the stability of the linear motion of the ball screw has been affected.
3、防止疲劳点的突变
3. Prevent sudden change of fatigue point
反复的直线运动,导轨上面就会出现疲劳点,而这个疲劳点就会出现凹坑的情况,所以在控制滚动导轨的时候一定要考虑到大负荷情况和承受力度是否均匀的情况。防止疲劳点出现突变,就能够确保导轨的有用性。
Repeated linear movement will lead to fatigue points on the guide rail, and pits will appear at this fatigue point. Therefore, when controlling the rolling guide rail, we must consider the large load and whether the bearing force is uniform. The usefulness of the guide rail can be ensured by preventing sudden changes in fatigue points.
滚珠丝杆对导轨的要求是比较高的,就怕反复的直线运动导致导轨上面出现疲劳点,导致疲劳点出现坑洼的情况下使得直线运动不能够准确有用。因此在选购的时候,导轨的耐磨性和承受力度问题一定要被考虑进去。
The ball screw has high requirements for the guide rail. It is afraid that the repeated linear movement will lead to fatigue points on the guide rail and pits on the fatigue points, so that the linear movement can not be accurate and useful. Therefore, when purchasing, the wear resistance and bearing strength of the guide rail must be taken into account.
