Wear is the main cause of the failure of the ball screw pair, which seriously affects its accuracy and service life. Therefore, it is necessary to build and analyze the wear model of ball screw pairs based on analyzing wear mechanism in depth. At present, the study of ball screw wear model mostly adopts the theory of adhesion wear. It is believed that the wear amount during normal wear period is proportional to time. But in fact, this conclusion cannot express the change of the whole wear process. Based on the wear mechanism of the ball screw pair, this paper deeply analyzes the influence of abrasive wear on the ball screw during the entire life cycle. And according to the Archard wear theory, a wear model considering the impact of abrasive particles is established. In this model, the wear of the ball screw pair is exponentially related to time. The experiments verify the applicability and accuracy of the model set out in this paper, which provides a theoretical foundation for the following research on the accuracy maintenance of ball screw pairs.
