2018-11-7 · The bearing plane becomes a cut line for the free-body diagram dividing forces — left and right or top and bottom relative to the bearing plane. Bearing loads are simply the reaction forces at the cut plane. Equations of static equilibrium return reactionary forces at this plane are: Σ Axial forces = 0. Σ Radial forces = 0. Σ Moments = 0
Get Price2011-9-13 · As a result, simple equations were obtained to calculate the static and dynamic equivalent loads, as well as the safety factors and bearing lives for slewing bearings under this condition. This method is used for the case when a bearing is mounted on a horizontal axis and loaded by a moment due to an eccentric radial load, such as large wheel change equipment for off-road heavy duty machinery.
