<P>PROBLEM TO BE SOLVED: To provide a thrust bearing device which enables uniformization of thrust loads shared by bearing pads, by making gaps (thicknesses of an oil film) even at all positions in the circumferential direction even when a thrust collar is inclined largely. <P>SOLUTION: This thrust bearing device 22A has a structure in which the thrust collar 23 is supported by a pair of bearing parts 24 arranged on both sides, and the bearing part 24 includes the two or more bearing pads 32 and the leveling mechanisms of the bearing pads 32 comprising two or more upper leveling plates 34 and lower leveling plates 35 arranged on the back 32b sides of the bearing pads 32. In the bearing device, hydraulic jacks 31 are placed respectively on the back faces 35b of the lower leveling plates 35, and thrust loads applied to the bearing pads 32 from the thrust collar 23 through the oil films in the gaps are received by the hydraulic jacks 31 through the upper leveling plates 34 and lower leveling plates 35. <P>COPYRIGHT: (C)2013,JPO&INPIT |
