The ball screw has the following common faults:

1.反向間隙大，定位精度差，加工零件尺寸不穩(wěn)定。

1. large reverse clearance, poor positioning accuracy and unstable dimension of machined parts.

滾珠絲杠副及其支撐系統(tǒng)由于長時(shí)間運(yùn)行產(chǎn)生的磨損間隙，將直接影響數(shù)控機(jī)床的傳動(dòng)精度和剛性。一般故障現(xiàn)象有反向間隙大、定位精度不穩(wěn)定等問題。根據(jù)磨損具體產(chǎn)生的位置，故障原因可分為以下幾類：

The wear clearance of ball screw pair and its supporting system due to long-time operation will directly affect the transmission accuracy and rigidity of CNC machine tools. Common fault phenomena include large reverse clearance, unstable positioning accuracy, etc. According to the specific location of wear, the fault causes can be divided into the following categories:

①滾珠絲杠支撐軸承磨損或軸承預(yù)加負(fù)荷墊圈配的不合適。TBI滾珠絲桿將回轉(zhuǎn)運(yùn)動(dòng)轉(zhuǎn)化為直線運(yùn)動(dòng)，或?qū)⒅本€運(yùn)動(dòng)轉(zhuǎn)化為回轉(zhuǎn)運(yùn)動(dòng)的理想的產(chǎn)品。上海曼魯?shù)慕z桿很不錯(cuò)

① The ball screw support bearing is worn or the bearing preload washer is not properly equipped. TBI ball screw is an ideal product that converts rotary motion into linear motion, or converts linear motion into rotary motion. The screw rod of Shanghai manlu is very good

②滾珠絲杠雙螺母副產(chǎn)生間隙、滾珠磨損。滾珠絲桿將回轉(zhuǎn)運(yùn)動(dòng)轉(zhuǎn)化為直線運(yùn)動(dòng)，或?qū)⒅本€運(yùn)動(dòng)轉(zhuǎn)化為回轉(zhuǎn)運(yùn)動(dòng)的理想的產(chǎn)品。滾珠絲杠是工具機(jī)械和機(jī)械上A常使用的傳動(dòng)元件，其主要功能是將旋轉(zhuǎn)運(yùn)動(dòng)轉(zhuǎn)換成線性運(yùn)動(dòng)，或?qū)⑴ぞ剞D(zhuǎn)換成軸向反復(fù)作用力，同時(shí)兼具高精度、可逆性和A率的特點(diǎn)。

② The double nut pair of ball screw produces clearance and ball wear. Ball screw is an ideal product that converts rotary motion into linear motion, or converts linear motion into rotary motion. Ball screw is a transmission element often used in tool machinery and machinery. Its main function is to convert rotary motion into linear motion, or torque into axial repeated force. At the same time, it has the characteristics of high precision, reversibility and a rate.

③滾珠絲杠單螺母副由于磨損產(chǎn)生間隙。

③ The ball screw single nut pair has clearance due to wear.

④螺母法蘭盤與工作臺(tái)之間沒有固定牢，產(chǎn)生間隙等。

④ The nut flange plate and the workbench are not firmly fixed, resulting in clearance, etc.

2.滾珠絲杠副運(yùn)動(dòng)不平穩(wěn)，噪音過大。

2. the ball screw pair is unstable and noisy.

①伺服電機(jī)驅(qū)動(dòng)參數(shù)未調(diào)整好。

① Servo motor driving parameters are not adjusted properly.

②絲杠絲母潤滑不良。

② Poor lubrication of lead screw nut.

③滾珠絲杠彎曲變形。TBI滾珠花鍵主要是由花鍵軸，循環(huán)套，花鍵套和滾珠這幾個(gè)部分組成，它與滾珠絲杠一樣是一種傳動(dòng)效率很高的，傳動(dòng)可逆的，同步性好，定期 精度高。

③ Bending deformation of ball screw. TBI ball spline is mainly composed of spline shaft, circulating sleeve, spline sleeve and ball. Like ball screw, it has high transmission efficiency, reversible transmission, good synchronization and high periodic precision.

④滾珠有破損。

④ The ball is damaged.

⑤絲杠與導(dǎo)軌不平行等！

⑤ The lead screw is not parallel to the guide rail!

通過檢測，如果確認(rèn)故障不是由于絲杠竄動(dòng)引起的。那就要考慮是否是絲杠螺母副之間產(chǎn)生了間隙，這種情況的檢測方法基本與檢測絲杠竄動(dòng)相同。用百分表測量與螺母相連的工作臺(tái)上，正反向轉(zhuǎn)動(dòng)絲杠，檢測出絲杠與螺母之間的A間隙，然后進(jìn)行調(diào)整。

Through inspection, if it is confirmed that the fault is not caused by the lead screw movement. It is necessary to consider whether there is a gap between the screw nut pairs. The detection method in this case is basically the same as that for detecting the movement of the screw. Use a dial indicator to measure the working table connected with the nut, turn the lead screw forward and backward, detect the a gap between the lead screw and the nut, and then adjust it.
