A new approach for determining the contact indentation of the wire race ball bearing in a three-axis simulating rotary table

This paper developed a new approach to determine the contact indentation between the wire and the ball in the wire race ball bearing with a diameter of 1000 mm used in a missile simulating rotary table. The material nonlinearity and geometric nonlinearity was considerer in the contact analysis by using the real stress-strain curve of the wire race tested on an Instron-5569 universal electron tension tester. The results obtained by our approach are in good agreement with the analytical results and the experimental results. The feasibility of the current approach is verified. This work contributes to controlling the preload of the wire race ball bearing and improving the servo control accuracy of the system.
