An accurate prediction method of initial value of high-speed ball bearing model is studyed and its gyroscopic torque is analyzed. First, a new iterative algorithm for high-speed ball bearings is proposed, in which the effects of gyroscopic torque and centrifugal force are considered. Then, to accurately predict the initial values for the proposed iterative algorithm, the combined displacements of bearings are calculated as the initial values according to the deformation superposition principle. The general applicability of this new iterative algorithm for high-speed ball bearings is demonstrated. Subsequently, the effects of combined loads, rotational speed, moment, and raceway groove curvature radius on the gyroscopic torque are discussed in detail. The results provide valuable guidelines for the reasonable selection of combined loads, rotational speed, and raceway groove curvature radii.
