Multiple defects are introduced on the outer race of vehicle gearboxes. The effect of the number of outer race defects in deep groove ball bearings are investigated using experimental and numerical methods. A three-dimensional model of the housing and outer race is developed using ABAQUS. Firstly, single defect located at 0˚and two defects located at 0˚ and 67.5˚ are analyzed. Then the number of defects was increased to three and the locations of the local defects are 0˚, 67.5˚ and 225˚. Finally the model with four defects located on the outer race at the angular positions 0˚, 67.5˚, 225˚ and 270˚, was investigated. The simulated data were also used to validate the experimental results.

Abstract


Multiple defects are introduced on the outer race of vehicle gearboxes. The effect of the number of outer race defects in deep groove ball bearings are investigated using experimental and numerical methods. A three-dimensional model of the housing and outer race is developed using ABAQUS. Firstly, single defect located at 0˚and two defects located at 0˚ and 67.5˚ are analyzed. Then the number of defects was increased to three and the locations of the local defects are 0˚, 67.5˚ and 225˚. Finally the model with four defects located on the outer race at the angular positions 0˚, 67.5˚, 225˚ and 270˚, was investigated. The simulated data were also used to validate the experimental results.
