The ball screw has the following common faults:

1.反向间隙大，定位精度差，加工零件尺寸不稳定。

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

滚珠丝杠副及其支撑系统由于长时间运行产生的磨损间隙，将直接影响数控机床的传动精度和刚性。一般故障现象有反向间隙大、定位精度不稳定等问题。根据磨损具体产生的位置，故障原因可分为以下几类：

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滚珠丝杠支撑轴承磨损或轴承预加负荷垫圈配的不合适。TBI滚珠丝杆将回转运动转化为直线运动，或将直线运动转化为回转运动的理想的产品。上海曼鲁的丝杆很不错

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滚珠丝杠双螺母副产生间隙、滚珠磨损。滚珠丝杆将回转运动转化为直线运动，或将直线运动转化为回转运动的理想的产品。滚珠丝杠是工具机械和机械上A常使用的传动元件，其主要功能是将旋转运动转换成线性运动，或将扭矩转换成轴向反复作用力，同时兼具高精度、可逆性和A率的特点。

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滚珠丝杠单螺母副由于磨损产生间隙。

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

④螺母法兰盘与工作台之间没有固定牢，产生间隙等。

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

2.滚珠丝杠副运动不平稳，噪音过大。

2. the ball screw pair is unstable and noisy.

①伺服电机驱动参数未调整好。

① Servo motor driving parameters are not adjusted properly.

②丝杠丝母润滑不良。

② Poor lubrication of lead screw nut.

③滚珠丝杠弯曲变形。TBI滚珠花键主要是由花键轴，循环套，花键套和滚珠这几个部分组成，它与滚珠丝杠一样是一种传动效率很高的，传动可逆的，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滚珠有破损。

④ The ball is damaged.

⑤丝杠与导轨不平行等！

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

通过检测，如果确认故障不是由于丝杠窜动引起的。那就要考虑是否是丝杠螺母副之间产生了间隙，这种情况的检测方法基本与检测丝杠窜动相同。用百分表测量与螺母相连的工作台上，正反向转动丝杠，检测出丝杠与螺母之间的A间隙，然后进行调整。

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.
