WebHydrodynamic Bearings. Hydrodynamic bearings use oil to support the rotor. The bearing itself has a clearance (typically 1.5 thousandths of an inch per inch of shaft diameter) on the shaft, and oil is injected between the bearing and shaft. The oil wedge created (the oil between the bearing and shaft at the load point) is only about 20–25 μm ... WebThis allowed the hydroelectric dam engineers to establish a safe and effective disassembly technique for future thrust bearing designs. Along with the stress and weld analysis, the model was analyzed for fatigue life based on a linear elastic fracture mechanics (LEFM) approach using the size of the largest crack to calculate the stress intensity factor (K1).
