Abstract

As running at high speed, the rolling elements in the rolling bearing will be influenced by centrifugal force and gyroscopic effect which will cause some significant differences from the time when the bearing is static. The main factors cause those differences include bearing contact angles, axial preload and bearing rotation speed etc. The way of calculating the distribution of bearing internal loads based on Jones & Harris’s model has been widely adapted. However, it involves too many equations, complicated iterations and slow convergence speed. In this paper, regularities and the algorithm of the bearing internal load distribution were analyzed to simplify the J&H bearing model providing a new simplified calculation procedure. The conclusion of comparison shows, under some certain occasions, a considerable reduction of time of numerical calculation using this method.
