The ball screw failure are diverse, there is no fixed pattern. Some failures are gradual onset fault, there must be a process of development of ball screw, with the increase in the use of time more and more serious; sometimes sudden failure Xingtai ball screw production, usually no obvious signs, but suddenly occurs, this failure is a common adverse effect of external factors and produced. So to determine the real cause of the failure Xingtai Ball enterprises through proper testing, is fast and accurate maintenance of the premise. Screw support bearings gap detection and repair, such as a dial indicator to measure the screw in the screw does not swing to reverse rotation pointer, indicating that the screw does not traverse. Such as dial pointer swing, indicating that the screw has a rocky ledge phenomenon. The difference between the maximum and minimum measurement dial indicator value is the axial screw ran away. At this point, we have to check whether the support bearing caps lock back, whether support bearings are worn failure, pre-load bearing washers are appropriate. If the bearing is no problem, just re-do the pre-load washer with it. If the bearing is damaged Ball Xingtai supply, the need to replace the bearing off again to do with pre-load washer, then back cap back tight. Screw axial movement lies in the accuracy of the size of the support bearing pre-load washers. Screw mounting accuracy of the ideal state is no positive and negative space, support bearings also have 0.02mm about interference.
