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, you need to replace the lost Langfang Ball bearing production, re-do the pre-load washer with ball screw Zhangjiakou production, 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. Single nut detection and repair for single nut ball screw, the gap between the screw nut is not adjusted. As detected screw nut gap. First check whether the screw and nut thread arc has been worn, such as badly worn and must be replaced complete set screw nut. Check the wear and tear such as ball screws slightly Zhangjiakou supply, you can replace the larger diameter balls to repair. First detected in the maximum gap screw nut, and converted into an increase in diameter of the ball, and then matching the right ball reassembled. Such maintenance is more complicated, it takes a long time, require high technical level. Zhangjiakou Ball Price | Ball | Shandong by Shandong Bot Bot Seiko Seiko Corporation.
