Hydrodynamic wedge principle
Web17 mrt. 2024 · The oil exerts a reaction force equal in magnitude on the rotor resulting in raising it upwards. This action is called the hydrodynamic or wedge effect.In other words, the heavy rotating rotor is supported by the hydrodynamic effect (viscous force). The main parameter controlling hydrodynamic bearings is called “load carrying capacity” which … Web14 dec. 2007 · This paper studies the hydrodynamic load support generated by a slip wedge of a slider bearing. The surface slip property is optimized to obtain a maximum hydrodynamic load support. A multi-linearity method was used to approach the slip control equation of two-dimensional (2-D) wall slip. It is found that the hydrodynamic pressure …

WebThe load in a Kingsbury bearing is carried by a wedge-shaped oil film formed between the shaft thrust-collar and a series of stationary pivoted pads or segments. This results in an extremely low coefficient of friction and negligible bearing wear. Albert Kingsbury (1863-1944) developed the principle in the course of bearing and lubrication ...
