However, in the long-term operation, ball screw is prone to lubrication failure, resulting in unstable operation and even unable to work properly. In this paper, the working principle of ball screw is analyzed, the mechanism and influencing factors of lubrication failure are studied, and corresponding solutions are proposed. The experimental results show that, by correctly selecting lubricants, maintaining the integrity of the lubricating film and regularly carrying out maintenance, etc., the lubrication failure of ball screw can be effectively prevented and solved.
