Influence of T-shaped Pressure-equalization Grooves on Static Characteristics of Aerostatic Bearings under Offset Loads [PDF]

Journal of Applied Fluid Mechanics
Aerostatic thrust bearings are highly susceptible to tilting under offset loads, which can cause bearing failure. To enhance the load-carrying capacity and tilting moment resistance of bearings under tilted operating conditions, this study proposes a ...
