A STUDY OF ELASTIC VIBRATIONS OF THE OUTER RACE OF A ROLLING ELEMENT BEARING.

Abstract

Elastic flexural vibrations of a thin ring (the outer race of a ball bearing) are investigated analytically using mathematical principles com mon in the theory of mechanical vibrations. The analysis is performed by first deriving a governing differential equation. Exact and ap proximate solutions of this equation are then presented for various geometrical configurations such as a free circular ring, a circular ring on a linear radial elasstic foundation, a circular ring rigidly supported at a number of equally spaced points, and a circular ring supported by a number of equally spaced identical linear springs (simulating the conditions in a bearing). A brief discussion of forced vibrations is also included. Finally, a numerical example is out lined for the SKF 6312 deep groove ball bearing. (Author)
