What should I do if the ball screw is stuck in daily use? What causes the ball screw to be stuck? Is it due to the damage of the screw itself?
Because the ball screw has high transmission efficiency, high transmission accuracy and positioning accuracy, but in the process of use, the performance of the ball screw is affected by external factors, such as stuck. Once the ball screw pair is stuck, if adding grease at this time can not solve the problem, it can only destroy the nut and disassemble the screw pair, which has always been a difficult problem in the assembly of the ball screw pair.
Two explanations for the ball screw stuck phenomenon:
1. Dust enters the inside of the nut, causing the ball to be stuck;
2. During the manufacturing process, the accuracy of the parts is not enough.
Although the use and research of ball screws are very extensive at present, there are very few relevant research papers on the jamming of ball screw pairs. Therefore, when the ball screw pair is stuck, it is very important to understand and analyze the cause of the stuck in time.
Process method:
1. Do not forcibly rotate the ball screw at this time, so as not to damage the parts and cause greater losses;
2. Remove the bearing fixing screws to see if the bearing has any problems and needs to be replaced;
3. Gently turn the lead screw with both hands to observe whether it is smooth (if it cannot be rotated gently, the lead screw can be disassembled);
4. After removing the lead screw, inject kerosene several times into the oil injection hole until the oil flowing out becomes clear (while injecting oil, blow it with an air gun faster), and then turn it gently;
5. If the above measures cannot turn the ball screw, you can only find a professional to deal with it. In this case, the parts are usually damaged.
Ball screws can be adapted to many different occasions, and sometimes problems occur. It is very important to do maintenance in daily life. In the process of normal use, regular lubrication should be paid attention to, kerosene should be used for cleaning, and dust-proof measures should be taken regularly. Check its working status, etc.
