Abstract: The paper presents a unitary model that is proposed to describe the quasi-dynamic behavior of ball bearings either with 2, 3 or 4 contact points (4PCBB). The model has five degrees of freedom and allows to: (i) predict the internal load distribution and calculating the rigidity matrix; (ii) determine the ball and cage kinematics by the principle of power minimization; and (iii) describe the interactions between various rolling bearing elements in terms of normal and tangential loading, and lubricant film thickness.
