Summary:Based on the theory of Hertz Contact, this paper presents a contact analysis method for large negative clearance four-point contact ball bearing. Take turntable bearing 3-645K for example, normal contact stresses between steel ball and inner and outer ring raceway are calculated under different negative clearance when bearing idling. The results show that contact loads of four contact points of the bearing increase with the absolute value of negative clearance, tiny changes of the negative clearance have a great effect on contact stresses.
