CALCULATION OF HYDROSTATIC THRUST BEARINGS,
Abstract
The author considers the use of hydrostatic bearings for eliminating semidry friction during starting and stopping conditions in high-power hydraulic generators where the combined weight of the wheel, rotor and shaft may be more than 1500 tons. The use of these bearings cuts the coefficient of friction during starting and stopping to a small fraction and reduces the energy of frictional forces to a minimum. Design of these bearings reduces to determining the necessary oil pressure, lifting capacity, rate of oil flow required for maintaining a film of a given thickness, power used in feeding the oil to the bearing and overcoming frictional forces and the temperature of the oil film. Formulas are given for determining these quantities in annular hydrostatic bearings used as the support surface for vertical shafts.
