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 out-of-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. |
