As a kind of precision transmission element, the ball screw bears a large load during the working process. It is widely used in automation equipment, such as industrial robots, automatic loaders, laser processing machines, handling devices, ATC devices of machining centers, etc. It is most suitable for use in combined devices of rotational motion and linear motion. In order to ensure its normal operation and extend its service life, maintenance and care are essential. Today we will briefly understand the maintenance and care methods of ball screws. 1. Clean regularly. During use, the ball screw may accumulate foreign matter such as dust and sand. These foreign matter will not only affect its normal operation, but also cause wear. Therefore, foreign matter inside the spline should be cleaned regularly with tools such as vacuum cleaners or air guns to ensure that its internal cleaning is unobstructed. 2. Lubrication. Select appropriate grease or lubricating oil and lubricate the ball screw regularly to reduce friction resistance, reduce wear and extend service life. At the same time, lubrication can also play a role in cooling and noise reduction, and improve the overall performance of the mechanical system. 3. Regularly check whether the bearing is damaged or severely worn. If there is any problem, it should be replaced in time; check whether the key teeth are deformed or damaged, and adjust or replace them if necessary; check whether the ball screw shaft end is bent or damaged, and repair or replace it if necessary. The ball screw threads also needs to be checked for foreign matter stuck inside. In addition, it should be ensured that all components are firmly installed without looseness to maintain the stability of the equipment. 4. Anti-corrosion treatment, when stored and idle, it should be avoided from being exposed to high humidity and strong acid and alkali environments. At the same time, regular maintenance and anti-corrosion treatment of the ball screw can extend its service life. The maintenance and maintenance of the ball screw must be carried out strictly in accordance with the machine manual and relevant maintenance requirements. It cannot be carried out blindly to avoid unnecessary damage to the ball screw. At the same time, maintenance and maintenance records should be kept to facilitate tracking and troubleshooting. In order to ensure production efficiency and product quality, it is crucial to master maintenance methods.
