Large reverse error of TBI ball screw is a common fault problem, which seriously affects the work progress. It appears that every technician must master the common faults and solutions of ball screw.

一、TBI滾珠絲桿反向誤差較大的原因是什么？

1、 What is the reason for the large reverse error of TBI ball screw?

①滾珠絲桿預緊力過緊或者過松

① The preload of ball screw is too tight or too loose

②滾珠絲桿制造誤差大或者軸向竄動

② Large manufacturing error or axial movement of ball screw

③絲桿軸滑板配合壓板過緊或者過松

③ Screw shaft slide plate is too tight or too loose

④其他機械的干擾

④ Interference from other machinery

⑤絲桿軸聯軸器錐套松動

⑤ Loose taper sleeve of screw shaft coupling

⑥絲桿支座軸承預緊力過緊或者過松

⑥ The preload of screw support bearing is too tight or too loose

⑦絲桿軸滑板配合楔鐵過緊或者過松

⑦ Screw shaft slide plate is too tight or loose with wedge iron

二．怎樣排除TBI滾珠絲桿的方向誤差：

2、 How to eliminate the direction error of TBI ball screw:

①重新調整或者修研，用0.03mm塞尺不入為合格

① Readjust or research again, and it is qualified if 0.03mm feeler gauge is not used

②用控制系統自動補償能間隙，同儀器測量并調整絲桿竄動

② The clearance can be eliminated by automatic compensation of the control system, and the screw rod movement can be measured and adjusted with the instrument

③調整預緊力，檢查軸向竄動值，使其誤差不大于0.015mm

③ Adjust the preload and check the axial displacement value, so that the error is not more than 0.015mm

④修理調整

④ Repair and adjustment

⑤調節各自導軌面均有潤滑油

⑤ Adjust to each guide surface with lubricating oil

⑥重新調整或者修研，使接觸率達到70%以上，用0.03mm塞尺不入為合格

⑥ Readjust or repair to make the contact rate above 70%, and it is qualified if 0.03mm feeler gauge is not used

⑦重新緊固并用百分表示反復測試

⑦ Retighten and repeat the test in percentage

⑧排除干涉部位

⑧ Eliminate the interference site

⑨修理調整或者加墊處理

⑨ Repair adjustment or cushion treatment

滾珠絲桿作為機床上更多人使用的高精密傳動元件，它的高精度特性給加工帶來的高速進給特性，但同時如果操作稍有不當就會容易出現較多的誤差，針對誤差的分析，上文從出現的原因以及解決方法進行了詳細的講解，希望對你有所幫助。

Ball screw is the most used high-precision transmission element on the machine tool, its high-precision characteristics bring unprecedented high-speed feed characteristics to the machining center, but at the same time, if the operation is slightly improper, it is easy to have more errors. According to the error analysis, the reasons and solutions are explained in detail, hoping to help you.
