  • A Vibration Model of Ball Bearings with a Localized

    To study the vibration mechanism of ball bearings with localized defects, a vibration model of a ball bearing based on the Hertzian contact stress distribution is proposed to predict the contact force and vibration response caused by a localized defect. The calculation of the ball-raceway contact force when the ball passes over the defect is key to establishing a defect vibration model.

  • Types of Bearings - How Bearings Work |

    In a ball bearing, the load is transmitted from the outer race to the ball, and from the ball to the inner race. Since the ball is a sphere, it only contacts the inner and outer race at a very small point, which helps it spin very smoothly.But it also means that there is not very much contact area holding that load, so if the bearing is overloaded, the balls can deform or squish, ruining the ...
