[0002] For bearings, accurate measurement of bearing friction torque and friction coefficient is an important index to measure and evaluate the dynamic performance of bearings. With the continuous improvement of aerospace bearing performance requirements in recent years, through the detection of friction torque and friction coefficient It is the focus of the bearing industry to scientifically determine the frictional resistance of bearings. By applying radial or axial loads to the bearings, the bearing friction torque and friction coefficient are measured, and the measurement method and measurement device that are not interfered by other external forces are applied to The bearing field belongs to the first new method, but the existing bearing friction torque and friction coefficient measurement methods and measuring instruments are mostly axially loaded and often have external force involved, and errors are prone to occur during measurement, and the measurement accuracy is low
