Abstract EN
The dynamic character of ball screw is the key factor that influences the machining accuracy of numerical control (NC) machine tool.
To improve the dynamic characteristics of the NC machine tool, it is necessary to study the dynamic characteristics of a ball screw.
In this paper, the kinematics of a ball screw mechanism (BSM) are studied to expound the dynamic process of the drive, and the load disturbance is considered to analyze the contact deformation based on the Hertzian contact theory.
The velocity relationships among the ball, screw, and nut are analyzed, and the influence of the contact deformation on the dynamic characteristics is simulated and investigated experimentally.
The results show that the relationships between the contact deformation, which is affected by the material characteristics, the contact angle, and the load of nut are nonlinear.
The contact deformation is a factor that cannot be ignored when considering the dynamic machining error of high-speed and high-precision machine tools.
