OIL DISPENSER OF ADJUSTABLE-BLADE PUMP-TURBINE UNIT Russian patent published in 1997 - IPC

Abstract RU 2075628 C1

FIELD: hydromechanical engineering. SUBSTANCE: oil dispenser has oil receiver, runner servomotor, and rods placed inbetween inside shaft. Rods are built up of two coaxial tubes rigidly fixed together by means of fastenings. Outer tube mounts support. Center of gravity of the latter is offset relative to shaft axis. Clearance between shaft and ribs is smaller than radial sag of outer rod near support due to centrifugal force at rated speed which ensures reliable contact between ribs and shaft until machine gains speed. EFFECT: improved design. 2 dwg
