The dynamic stability of high-speed rotor systems is highly dependent on the interaction between bearing geometry and lubricant rheology. The present work examines the stability of hydrodynamic ...

Table 1 Summary of articles employing commercial computer codes. The current work is a continuation of Awad et al. 61 ’s analysis to investigate the combined effects of axial changes in bearing ...

Journal bearing design is complex. It involves optimizing clearances, bearing length, minimum film lubricant, viscosity, flow rate, and inlet slots. Design equations are available, but their solution ...

• Large bearings need help to generate a lubricating oil film at low speeds. • Pockets in journal and thrust bearings supplied with pressurized lubricant provide hydraulic lift. • Optimize pocket ...

A new tapered bearing assembly, developed specifically for roller-cone rock bits, significantly increased bit life for a Middle Eastern operator. This technology can help oil and gas customers avert ...
