STUDY OF LOAD DISTRIBUTION BETWEEN ROLLING BODY

The load distribution between rolling elements of a non-rotating bearing with increasing interference fit of the outer ring is investigated. It is found that the unevenness of the load distribution between rolling elements decreases, and increases with increasing clearance fit. With increasing clearance fit, the load on the central rolling element increases for all loads applied to the bearing. To establish the influence of the main factors and their interaction on the change in the coefficient of load distribution between rolling elements and to obtain a mathematical model, the studies were carried out using multifactorial experiment planning. The signs at the coefficients of the model show that in order to achieve the most uniform load distribution between rolling elements, the thickness of the polymer coating should be at the upper level, and the radial clearance of the bearing and the load on the bearing should be at the lower level.
