摘要： PROBLEM TO BE SOLVED: To provide a rolling bearing mechanism making a pre-load providing function and a damping function compatible.
SOLUTION: An intermediate ring 12 is inserted into an outer side in the radial direction from an outer ring 8 of a bearing 3 and an inner side from a housing 11 in play. A channel 13 is provided on an inner side of the intermediate ring 12 to hold adhesive lubricant between the intermediate ring 12 and the outer ring 8. A mechanical damper 16 as a damper member is fitted between the intermediate ring 12 and the housing 11. Pre-load is given to the outer ring 8 in the direction of central axis of the bearing 3. When the rolling bearing mechanism is constituted as mentioned above, pre-load is properly transmitted to the outer ring 8 without being absorbed by the damper member 16. A damper member 23 functions so as to damp vibration transmitted to the intermediate ring 12 from the bearing 3. Consequently, this rolling bearing mechanism damps vibration of the shaft by the damper members while applying proper pre-load continuously to support the shaft rotating at ultra-high speed.

摘要： PROBLEM TO BE SOLVED: To suitably connect both turbine and generator shafts.
SOLUTION: Firstly, the eccentric centers of both shafts are measured using a tool 200, a flange 201 is fitted in the inlay 33 of a compressor scroll 31 in a gas turbine side to judge whether or not a measuring cylinder 203 can be extrapolated on a spline shaft 4 and further, a flange 202 is fitted in the inlay 32 of a casing 17 in a generator side to judge whether or not the cylinder 203 can be extrapolated on a spline shaft 6. In the above judgments, when the eccentric centers of both shafts are within a range of tolerance, the gas turbine and generator are connected through a coupling 3. On the other hand, when the eccentric center of one or both of the shafts exceeds the tolerance, the cause of failure is investigated to correct the failure or replace a component. Then, the tolerance is measured again using the tool 200.

摘要： PROBLEM TO BE SOLVED: To sufficiently meet short starting time, to ensure high efficiency, and to maintain downsizing.
SOLUTION: A back plate 42 is fixed at a seal housing 25 at relatively low temperatures, and the back plate 42 abuts on a turbine nozzle 20 conditioned to relatively high temperatures. As a result, the back plate 42 maintains a contact condition with the turbine nozzle 20, and is not moved with the thermal expansion of the turbine nozzle 20. Therefore, the back plate 42 is not brought into contact or interference with a turbine rotor 22. At the time of rated operation of the turbine, the back plate 42 and the turbine rotor 22 maintain a preferable clearance C, thus sufficiently meeting short start time, ensuring high efficiency, and maintaining downsizing.
