  • Stiffness of deep-groove ball bearings - ScienceDirect

    As bearing stiffness is given in manufacturers' catalogues and handbooks it would be useful to derive an equation to predict this parameter. Such an equation for predicting the stiffness of deep-groove ball bearings is derived and expressed in terms of the available bearing dimensions.

  • Does rolling bearing stiffness always increase with ...

    2016-9-8 · If a bearing under pretension is loaded radially, the bearing stiffness can decrease with increased radial load. The reason is the contact area again, which will be decreased as the load for some rolling elements will decrease. Following diagram shows the axial and radial stiffness of a 6204 deep groove ball bearing without clearance.

  • 2188. The influence of elastohydrodynamic lubrication on ...

    presents an enhanced bearing stiffness matrix for a deep groove ball bearing by including the elastohydrodynamic lubrication (EHL) effects in the ball-raceway contact. The bearing model is subjected to the coupled lateral-translational loads. The EHL contact is calculated by employing the multilevel method.

  • The influence of the lubricant film on the stiffness and ...

    2014-1-1 · Whether the bearing stiffness and damping increase or decrease due to the formation of a lubricant film is highly dependent on the temperature conditions. To conclude, the paper shows a clear link between the formation of a lubricant film inside a deep groove ball bearing and a resulting variation of the bearing dynamics.

  • A comprehensive study on the speed-varying

    2019-6-1 · 1. Introduction. Ball bearing as the most important supporting and motion transmission component, is widely used in various rotating machinery. In general, for the rotor-bearing system, bearing outer ring is fixed with housing and bearing inner ring rotates with the center shaft by the interference fit, and the external loads and vibrations are transmitted from the rotor to housing …
