Ball screw nut is a very precise product. If you are not careful during installation, the ball will be misaligned and the screw will be stuck and the groove will be worn. If you feel tight, don't use brute force. Squeeze the nuts in.
1. Clean the ball screw nut and steel ball with clean kerosene.
2. The steel ball cannot be lost after falling, otherwise the life of the screw will be greatly reduced if the nut is installed in the screw. (80% of the steel balls can ensure the normal positioning and operation of the screw.)
3. For the installation of the internal circulation screw, be careful not to install the steel ball in the non-sliding groove between the two circulators. The length of the circulation path), it will bite the lead screw, and the circulation will not be smooth, which will cause backlash and irregularity.
4. Put the ball into the spiral groove. Note that not all the spiral grooves are filled. The balls are placed according to the principle that a ball stopper is a circular park. I see that your nut seems to be 4 ball stoppers, that is, 4 circular parks.
5. When placing the steel balls in the spiral groove, pay attention that not all the circulation paths are filled. The balls are placed according to the principle of one reverser and one circulation ring. The nuts are 4 reversers, that is, 4 cycles ring. After placing the steel balls in each circulation circle, there will be a small space (approximately a distance of 3/4 of the diameter of the steel balls) to facilitate the rolling movement of the steel balls in the circulation path.
6. It is a schematic diagram of the internal circulation screw. One circulation channel corresponds to one inverter. The circulation channels are not connected to each other and are detected independently. The steel ball will be stuck if you put it in. Please pay attention when installing.
7. Screw the nut into the screw and rotate the nut forward and backward to check whether the nut runs smoothly. If it is smooth, it means OK.
8. Ball screw is a precision mechanical product. Generally speaking, after an abnormal phenomenon occurs, it is best to stop the machine immediately and send the screw to a professional maintenance unit for repair. Although it can be installed by a certain method, it is easy to damage the screw due to installation errors.
