ABSTRACT:
A pressure-fed journal bearing for a steam turbine is shown having a generally tangentially oriented oil inlet discharging at the horizontal centerline of the supported shaft to utilize the pressure head of the oil and retain laminar flow in the direction of rotation of the shaft. Seals are disposed in the axial ends of the bearing to minimize end leakage and confine the oil flow to an outlet channel generally opposite the inlet and likewise tangentially oriented to receive the discharged oil with minimal bearing losses. The oil flow rate through the bearing can be regulated by an orifice in the outlet or inlet channel.
