Hydraulic machine i.e. Francis turbine, has axial bearing defined between shaft's lower surface or foot, and fixed dowel that is rotatably fixed with respect to axis, where pipe supplies water to axial and radial bearings via branches

摘要

The machine has an annular axial hydrostatic bearing (100) defined between an axial lower surface (512) of a shaft (5) or a foot (51) rotatably integrated to the shaft, and a fixed dowel (101) that is rotatably fixed with respect to a vertical axis (X5). A radial hydrostatic bearing (300) is defined between an external radial peripheral surface (513) of the shaft or the foot, and an annular trim (301) that is rotatably fixed with respect to the vertical axis. A pipe (200) supplies water to the bearings via branches (201, 202).
