“…The control moment gyroscope is widely used in satellites and other spacecraft due to its high precision, high reliability, and long life [1][2][3]. A pair of angular contact ball bearings are the key components supporting the two ends of the rotor in the control moment gyroscope and affecting the output moment of the control moment gyroscope under high-speed conditions and the time-varying moment [4].…”

In this paper, a dynamic simulation analysis model was established for CMGB (control moment gyroscope bearing) under the conditions of time-varying moment. The influences of the moment’s response time, axial preload, and working temperature on the dynamic characteristics and friction torque of CMGB were analyzed, and the relevant verification tests were conducted. The results show that the friction torque fluctuation of CMGB directly corresponds to the dynamic characteristics. The faster the response time of the time-varying moment, the larger the friction torque fluctuation of CMGB. The larger preload minimizes the difference in the ball’s loading state, which is the actual reason for reducing the friction torque fluctuation. Moreover, as the working temperature increases, the friction torque fluctuation of CMGB decreases.
