Abstract
This work proposes an approach to calculate the load distribution among balls in a four-point contact slewing bearing considering manufacturing errors and ring stiffness. The model is established upon the formulation and minimization of the potential energy of the system. Calculations are done for a particular bearing considering different assumptions and the results are presented. It is concluded that manufacturing errors affect significantly the load distribution in idling conditions, but not under external loads. Moreover, ring flexibility is proved to have a great effect in the load distribution in idling conditions.
