Dynamic Capacity of Rolling Bearings

Abstract This paper is a condensation of a comprehensive theory for fatigue failure in rolling bearings. The character of bearing fatigue failures is analyzed, and the effect of the volume of stressed material is assessed by means of modification of Weibull’s statistical theory of failure. The variables affecting bearing capacity are examined, and general formulas are set up relating the variables to the bearing capacity. Unknown exponents in the formulas are evaluated by means of extensive tests, and the final formulas are compared to experimental results.
