Abstract: The barring gear assembly is designed to drive in rotation a shaft of a turbo-alternator group having an axis of rotation A. The barring gear assembly includes a main wheel fixed on said shaft and defining lateral sides located on either side of the axis of rotation A, a barring gear module having a support piece on which is mounted a clutch system for coupling and uncoupling a secondary shaft to and from the main wheel, the secondary shaft being driven by an auxiliary motor, and the barring gear module being positioned on one of said lateral sides (C1) of the axis of rotation A.

Abstract: A hydrodynamic journal pad bearing is provided having several pads circumferentially distributed around the rotor of a large steam turbine with each pad mounted onto a platform separating the pad from a cylindrical cage in turn connected to the floor of a hall housing the turbine and having an interface between at least one of the several pads and the platform on which the at least one of the several pads is mounted is formed such as to include at least two areas with different curvatures to increase the stiffness of the interface in the event of a relative movement between the pad and the platform.
