A APDL program is developed for analyzing the contact stress of journal bearing pair of roller cone bit. The 25 contact stress cases of different clearance fit(including clearance of large bearing is bigger, equal to and smaller than that of small bearing) journal bearing pair of the 8 1/2XXX roller cone bit are analyzed. The result is that the maximum contact stress is less when the clearance of large journal bearing pair is smaller than or equal to that of small journal bearing pair.

First, the theory of fretting wear and studies on fretting fatigue were introduced and the parametric method was used in the process of creating the model of dovetail joints in UG software. The elastic contact problem is analyzed in finite element method and is used to the parameters' distribution and contact stress of the joint are obtained on the base of ANSYS code. With the effect factor of load frequency, the prediction method of fretting fatigue life of dovetail joint under low and high/low cycle complex load is proposed. The proposed model and the approach were verified by experiments.
