Starved lubrication analysis of angular contact ball bearing based on a multi-degree-of-freedom tribo-dynamic model

open access: yesFriction, 2023
When the oil supply is not adequate to maintain the ideal lubrication, angular contact ball bearing will enter into the starved lubrication regime resulting in the potential performance degradation and consequently the severe failures.

Dynamic Performance Analysis of Cage in Four-Point Contact Ball Bearing

open access: yesLubricants, 2022
Due to the special structure of double-half inner rings, four-point contact ball bearings are prone to uneven forces in the inner raceway during movement, which affects the dynamic performance of the rolling element and cage, and even leads to cage ...

Frustrated Bearings

open access: yesPhysical Review Letters, 2020
In a bearing state, touching spheres (disks in two dimensions) roll on each other without slip. Here we frustrate a system of touching spheres by imposing two different bearing states on opposite sides and search for the configurations of lowest energy dissipation. If the dissipation between contacts of spheres is viscous (with random damping constants)
