相信很多用戶在使用滾珠絲杠的時候難以避免會出現一些故障問題，作為一種精密零部件，一旦發生故障，可能導致一系列相應的問題。下面導軌絲杠廠家來講講滾珠絲杠穩定性不夠的表現吧。

It is believed that many users will inevitably encounter some fault problems when using ball screws. As a precision component, once a fault occurs, it may lead to a series of corresponding problems. Let's talk about the performance of insufficient stability of the ball screw from the guide rail lead screw manufacturer.

反向間隙大，定位精度差，加工零件尺寸穩定性不夠：

Large reverse clearance, poor positioning accuracy, and insufficient dimensional stability of machined parts:

由于滾珠絲杠副及其支撐系統在長期的使用中難免會產生磨損間隙，這會直接影響數控機床的傳動精度及剛性，一般故障的現象是反向間隙大、定位精度不穩定等問題。故障的原因可能是滾珠絲杠支撐軸承磨損或軸承預加負荷墊圈配的不合適、滾珠絲杠雙螺母副產生間隙、滾珠磨損這三種。

Due to the inevitable wear clearance of the ball screw pair and its support system during long-term use, this will directly affect the transmission accuracy and rigidity of CNC machine tools. Common failures include large reverse clearance, unstable positioning accuracy, and other issues. The cause of the failure may be wear of the ball screw support bearing or improper fitting of the bearing preload washer, clearance of the ball screw double nut pair, and ball wear.

滾珠絲杠副運動平穩性差或噪音過大。導致這種現象的原因可能是未調整好伺服電機驅動參數、絲桿絲母的潤滑不足或者滾珠絲杠彎曲變形。

The ball screw pair has poor movement stability or excessive noise. The reasons for this phenomenon may be that the servo motor driving parameters have not been adjusted properly, the lubrication of the lead screw nut is insufficient, or the ball screw is bent or deformed.

出現竄動問題一般是由于滾珠絲杠副進給傳動的潤滑狀態欠佳、絲杠支承軸承的壓蓋壓合情況不好、滾珠絲杠副滾珠有破損、絲杠支承軸承可能破裂、軸向預加載荷過小，使進給傳動鏈的傳動間隙過大引起絲杠傳動時候的軸向竄動。

The occurrence of play problems is generally due to poor lubrication of the feed transmission of the ball screw pair, poor press fit of the gland of the lead screw support bearing, damage to the ball of the ball screw pair, possible fracture of the lead screw support bearing, and too small axial preload, resulting in excessive transmission clearance of the feed transmission chain, causing axial play during the lead screw transmission.

滾珠絲杠副進給傳動的潤滑狀態不良、軸向預加載負荷過大、絲杠與導軌不平行、螺母軸線與導軌不平行或絲杠彎曲變形時都會引起過載報警。一般會在CRT上顯示伺服電動機過載、過熱或過流的報警，或在電柜的進給驅動單元上，用指示燈或數碼管提示驅動單元過載、過流信息。

Poor lubrication of the ball screw feed transmission, excessive axial preload, non parallelism between the screw and the guide rail, non parallelism between the nut axis and the guide rail, or bending and deformation of the screw can cause an overload alarm. Generally, an alarm for servo motor overload, overheating, or overcurrent is displayed on the CRT, or an indicator light or digital tube is used on the feed drive unit of the electric cabinet to prompt the drive unit for overload, overcurrent information.

爬行問題通常是發生在啟動加速段或低速進給的時候，多因進給傳動鏈的潤滑狀況不佳、外加負載過大等因素引起。

Creepage problems usually occur during startup acceleration or low speed feed, and are often caused by factors such as poor lubrication of the feed transmission chain, excessive applied load, and so on.

需要特別注意的是，連接伺服電機和滾珠絲杠的聯軸器，若連接松動或聯軸器本身缺陷，如裂紋等，會導致滾珠絲杠轉動和伺服電機的轉動不同步，從而導致進給運動時快時慢，導致爬行的問題。更多相關事項就來我們網站http://www.zsdress.com咨詢！

Special attention should be paid to the fact that if the coupling connecting the servo motor and the ball screw is loose or the coupling itself has defects, such as cracks, it can cause the ball screw rotation and the servo motor rotation to be out of sync, resulting in fast and slow feed motion, leading to a creeping problem.
