The paper focuses on local phenomena modelling in the ball-and-socket pivot of tilting pad journal bearings. It provides an in-depth analysis of the influence of nonlinear normal force and friction forces generated in the pivot on the dynamic behaviour of the bearing. Contemporary works often employ the Hertz theory, which is valid for non …

6.5: Bearing Friction
No headers. A bearing is the machine element used to support a rotating shaft. Bearing friction is the friction that exists between the rotating shaft and bearing that is supporting that shaft.

Bearing Load Calculation
loads act on a bearing at the same time, the hypothetical load acting on the center of the bearing which gives the bearings the same life as if they had only a radial load or only an axial load is called the dynamic equivalent load. For radial bearings, this load is expressed as pure radial load and is called the dynamic equivalent radial load.

The bearing load acting on each bearing is the result of several different forces: not only is there the weight of the rotor to be supported, but, as discussed previously, there are also the reaction forces from the gear tooth interactions and thrust collars.
