A CALCULATION OF RELATIVE MOVEMENTS OF RINGS OF A TAPERED ROLLER BEARING WITH INERTIAL FORCES AND GYROSCOPIC MOMENTS

Abstract

Tapered bearings are important structural elements of machines and devices because of their distinctive features, i.e, high axial and radial load capacities, as well as moment loads. When solving the problems of the rotor dynamics of rotating machines, great importance is played by the calculation of the relative movements of the bearing rings, which in principle can be determined by the finite element method. However, models consisting of finite elements are practically unsuitable for solving problems of rotary dynamics, since they usually require unacceptably large computer resources. In this regard, in this paper, a new model has been developed for calculating the relative movements of bearing rings based on the energy approach, taking into account inertial forces and gyroscopic moments. With the use of this model, the elastic characteristic of a tapered roller bearing typed 30208A at different angular velocities was investigated. In comparison with known results, results of developed model show their good veracity.
