Nonlinear effects in rolling bearings are related to contact deformation of rolling elements, clearances between rolling elements and the bearing races. The rotor motion with such bearings is quite complicated– from ordered to chaotic. The article presents the roll bearing model taking into account contact stiffness, clearances between rolling elements and races, external loads in correspondence with Hertz theory. Using it, behaviour of unbalanced rotor system with nonlinear bearing was investigated.
