Patent number: 7052017Abstract: The so-called comb-type labyrinth sealing device (S1) is disposed in a gap between a rotor blade (2), i.e. a rotating member, and a labyrinth packing (9), i.e. a stationary member. The sealing device (S1) has a plurality of sealing fins (F1, F2) arranged on the opposite sides of the gap opposite to each other. The sealing fins are axially spaced apart at unequal pitches, and hence a possibility that some of the clearances between the opposite sealing fins (F1, F2) decrease when a casing holding the labyrinth packing (9) and a rotor (1) are axially displaced relative to each other due to the difference in thermal expansion between the rotator and the casing increases.Type: GrantFiled: February 28, 2002Date of Patent: May 30, 2006Assignee: Kabushiki Kaisha ToshibaInventors: Tatsuro Uchida, Masataka Kikuchi

Patent number: 6790002Abstract: The present invention solves problems of securing high-temperature strength at elevated temperatures and of preventing steam leakage that arise when high-pressure, high-temperature steam is used for driving a steam turbine, and problems of preventing the occurrence of rubbing due to the suppression of the excessive elongation difference and of minimizing steam leakage from shaft seals. A double-wall casing structure is arranged at an area corresponding to stages from a high-pressure first stage (7) to a predetermined high-pressure stage arranged on an upstream side of a high-pressure final stage (8); and a single-wall casing structure is arranged at an area corresponding to stages which follows said predetermined high-pressure stage.Type: GrantFiled: December 23, 2002Date of Patent: September 14, 2004Assignee: Kabushiki Kaisha ToshibaInventors: Morikazu Kitazawa, Masataka Kikuchi, Kazuo Aoyagi, Nobuo Okita, Hiroyuki Oohira
