This article presents the generalized cumulative model of wear kinetics for the sliding bearing elements in the case of single area and single-and-double area contact for different phases of rotating a shaft with a small contour ovality and a bushing with a circular contour. As a result of the performed numerical analysis, the regularities of the change in the initial maximum contact pressure due to shaft rotation and shaft changes due to wear are described, as well as the durability of the bearing and the linear wear of the bushing and shaft depending on the size of ovality are discussed in the work. The contact pressures are considerably higher in the zones of double-area contact than in the zones of single-area contact. The shaft ovality increases the bearing durability and reduces the hob wear. The results are presented graphically by means of charts.

The generalized cumulative model of wear is employed to solve the tribocontact problem for plain bearings where journals have small lobing (ovality, trilobing, tetralobing). The case of mixed-area contact interaction between the shaft and bush is examined. The study investigates the effect of lobing both on variations in the maximum contact pressures during a full revolution of the shaft and on bearing durability. Regularities concerning this effect are determined. It was found that lobing causes a significant increase in the contact pressures depending on the extent of shaft outof-roundedness and type of lobing. Specifically, ovality increases the bearing durability by 1.32 times; compared to the durability of a bearing with a circular section shaft, trilobing increases the bearing durability by 1.25 times, whereas tetralobing decreases the bearing durability even by 1.2 times.
