Mathematical Modelling of Load and Stress Distribution in a Ball Bearing

Abstract

External load of ball bearing is transferred from one ring to the other one through the balls. Load distribution between balls is unequal. Degree of load distribution inequality depends on internal geometry of bearing (number of balls, internal radial clearance) and external load. The new mathematical model of load distribution is developed introducing new value - the load distribution factor into the classic theory of ball bearings. Developed mathematical model includes all relevant influences on ball bearing load distribution (bearing internal geometry and load). The new load distribution model is used for description of stress distribution in the bearing.
