- Abstract
In this paper, the roller bearings partial wear due to extreme inclined load caused by poor installation is investigated. First, based on non-Hertz contact theory, a quasi-static model of roller bearing with inclined load is established by the influence coefficient method. The influence of deflection angle between the inner ring and outer ring on the non-uniform contact characteristics is discussed. The finite element model of roller bearing housing is established and optimized by the theoretical results. The double-loading zones characteristic of roller bearings caused by the inclined installation of the housing is analyzed. The influence of the extreme position of the rollers on the deformation of the bearing is also considered. The partial wear experiment of the bearing is carried out. The contact surface roughness and deformation of the outer ring are measured. Fusing the analytical analysis, finite element analysis, and experiment, the effects of external inclined loads, rollers extreme positions, and wear on the deformation of the contact surface of the outer ring are systematically studied to reveal the mechanism of partial wear.
