Comparative Study on Dynamical Performance of hybrid ceramic and steel ball screw mechanism based on multi-body dynamic simulation

Current ceramic is used as the material for high speed ball bearing for its low density and lubricant performance; however the most common material for the high speed ball screw is chromium-molybdenum steel rather than the ceramic.Following the hertz contact and raceway control theory of the ball screw and considering the centrifugal force and gyroscopic moment acting on the ball screw,the dynamic model of high-speed ball screw was set up.The effects of different types of working ceramic ball chains on the mechanical properties of the ball screw were studied and compared through multi-body dynamic simulation.The result has shown that these factors affect the dynamic characteristic of ball screw dramatically,and the dynamic characteristic of ball screw at high speed is greatly different from that of ball screw made by chromium-molybdenum steel.
