A hydrodynamic journal pad bearing (10) is provided having several pads (131, 132, 133) circumferentially distributed around the rotor (12) of a large steam turbine with each pad (131, 132, 133) mounted onto a platform (121, 122, 123) separating the pad (131, 132, 133) from a cylindrical cage (11) in turn connected to the floor of a hall housing the turbine and having an interface between at least one of the several pads (131, 132, 133) and the platform (121, 122, 123) on which the at least one of the several pads (131, 132, 133) 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 (131, 132, 133) and the platform (121, 122, 123). |
