Purpose. Research of regularities of angular-contact ball bearings kinematic and elastic-deformative characteristics changing on high rotational frequencies.
Design/Methodology/Approach. Elastic-deformative model of revolving bearing based on solving of the task of functional link establishing between vector of external load on bearing, vector of relative displacements of bearing rings and vector of reaction with consideration of inertial loads influence.
Findings. Calculated and experimental results of kinematic and stiffness of spindle unit angular contact ball bearings are presented.
Main conditions, assumed during spindle bearing elastic-deformative model development and procedure of its kinematic, elasticdeformative and power characteristic determination are presented. For practical realization of the model, special program module in MATLAB system have been developed.
Originality/value. Regularities of rotational frequency, axial preload, temperature and material of spindle bearings influence on their kinematic and elastic-deformative characteristics are established.
