ABSTRACT:
A method and apparatus for counteracting an axial thrust imparted to a shaft of a fluid turbine is disclosed. The apparatus includes first and second shaft thrust plates affixed to the shaft. A first, stationary axial thrust bearing engages the first shaft thrust plate. A second axial thrust bearing, having components which are axially movable, engages the second shaft thrust plate. The apparatus also includes a system of fluid lines for supplying pressurized fluid to bellows-like thrust chambers in the second axial thrust bearing. The source of the pressurized fluid is fluid compressed by a compressor mounted on the shaft.
