【Abstract】 The measurement principle of bearing friction torque based on damped vibration is discussed. The algorithm and implementation of bearing friction torque measurement are proposed. By analyzing the maximum angle characteristics of the first and last pendulum to the left side of the collected data,the utilization is utilized. The law of conservation of energy is transformed to obtain the relationship characteristic of bearing friction torque. Using a special bearing testing equipment,a large number of test tests were carried out for analysis and verification.The feasibility of the method was verified by experiments. The analysis results show that the test results are basically consistent with the calculated results,and the technical development of the ball bearings used in high-precision systems is played. Certain promotion.更多还原
