Troubleshooting Ball Screws

迷茫的维修

Here are 10 things to check if you’re having ball screw issues. Is the ball screw assembly losing accuracy or showing signs of damage? Get a free repair analysis from a professional – Dynatect LSI can repair, rebuild, and replace all brands.


Checks to be made (while the ball screw assembly is still in the machine) include:

1. Run a power check. If you show an overload condition, the ball screw may be close to permanent failure.

2. Measure the backlash between the screw and the nut.

3. Check for wipers on both ends of the nut assembly if possible. Warning signs include: Missing wipers, excessively worn brush or plastic wipers, and felt wipers in any condition. Felt wipers trap chips and grinding compounds which can cause permanent wear and failure.

4. Check the exposed screw for rust, pits, and chatter marks in the ball groove.

5. Check for heavy screw wear in areas where the nut travels the most. Compare these worn spots with areas the nut does not travel as often.

6. Make sure the lubrication system is working properly.

Using a light oil will both lubricate and flush contaminants out of the ball nut.
Higher lube system pressures will insure better flushing and lubrication.
Make sure you can see the oil.
Determine whether the oil is clear or contaminated.
If there is not properly working lube system, remove the ball screw as soon as possible.
This is a good time to also check the lube system for slides, ways, spindles, bearings, etc.
7. Check the ball screw alignment.

The alignment should be within a few ten-thousandths of an inch.
Try to determine if the screw is bent.
Check for slide wear and slide alignment.
8. If the nut is accessible, unbolt the nut from the housing and rotate the nut.

If the nut feels rough when turning, we suggest removing the unit before further damage occurs.
Check for proper alignment of the nut to the housing.
Make sure the bolts holding the nut in the housing are properly tightened.
9. If you ever find steel balls laying on the floor or in the machine, shut the machine down immediately to avoid serious damage and injury.

10. All vertically mounted ball screw assemblies and vertically mounted acme screw assemblies should be checked regularly as a normal safety procedure.

如果你有滚珠丝杠问题，这里有10件事情要检查。滚珠丝杠组件是否失去精度或有损坏迹象？从专业人员那里获得免费的维修分析--Dynatect LSI可以修理，重建和更换所有品牌。


检查（滚珠丝杠组件仍在机器中）包括：

1.执行电源检查。如果显示过载情况，滚珠丝杠可能会接近永久性故障。

2.测量螺钉和螺母之间的间隙。

3.如果可能，检查螺母组件两端的擦拭器。警告标志包括：刮水器丢失，过度磨损的刷子或塑料刮水器，以及任何情况下感觉到的刮水器。毛毡刮水器捕集碎屑和研磨化合物，可能导致永久磨损和故障。

4.检查暴露的螺丝是否有锈斑，凹槽和球槽中的咔哒声。

5.检查螺母行进最多的地方螺丝磨损严重。将这些磨损的斑点与坚果不经常出入的区域进行比较。

6.确保润滑系统工作正常。

使用轻油将润滑并将污染物冲出滚珠螺母。
更高的润滑系统压力将确保更好的冲洗和润滑。
确保你能看到油。
确定油是否清除或污染。
如果润滑系统工作不正常，应尽快拆下滚珠丝杠。
这也是检查润滑系统滑块，方式，主轴，轴承等的好时机。
7.检查滚珠丝杠的对齐情况。

对齐应该在几十分之一英寸的范围内。
尝试确定螺丝是否弯曲。
检查滑块磨损和滑块对齐。
8.如果可以接近螺母，则从壳体上取下螺母并旋转螺母。

如果转弯时螺母感觉粗糙，我们建议在进一步损坏发生之前拆下本机。
检查螺母是否与壳体正确对齐。
确保将螺母固定在外壳中的螺栓已经拧紧。
9.如果您发现铺设在地板或机器上的钢球，请立即关闭机器，以免造成严重的损坏和伤害。

10.所有垂直安装的滚珠丝杠组件和垂直安装的极限螺钉组件都应按照正常安全程序定期检查。
