    摘要： A sealing mechanism includes a pair of space forming rings which face each other and are configured for surrounding a shaft body, an outer bellows-joint having one end connected to an outer periphery of one of the space forming rings and another end connected to an outer periphery of the other of the space forming rings, and an inner bellows-joint having one end connected to an inner periphery of one of the space forming rings and another end connected to an inner periphery of the other of the space forming rings. Each of the inner bellows-joint and the outer bellows-joint is a corrugated plate. The space forming rings space the inner bellows-joint and the outer bellows-joint apart from each other such that the inner bellows-joint and the outer bellows-joint do not come in contact with each other.

    摘要： A first seal member includes a double-structure bellows in corrugated form, and vibration control device provided on the outside of the bellows such as to cover part of the bellows. A flat portion that is not in corrugated form is provided in part of the bellows. The vibration control device is provided in circumferential direction on an outer surface of the flat portion, and made up of a ring-shaped rib having a plurality of holes in a circumferential direction and weights inserted in the holes provided in a wall of rib. Natural frequency is adjusted by adjusting the number of weights, thereby preventing resonance between the natural frequency of the first seal member and the rotational frequency of rotor from occurring.

    摘要： Providing a sealing mechanism provided with bellows-joints, the sealing mechanism being manufactured without surplus time and labor; thereby, the natural frequencies regarding the sealing mechanism surrounding a to-be-sealed shaft body are easily handled. Around a rotor shaft 26 of a steam turbine 10, between an outer turbine casing 12 and a gland 32, a sealing mechanism 40A is provided; the sealing mechanism is provided with an outer bellows-joint 46 and an inner bellows-joint 48, both the joints being arranged without mutual contact; the left and right ends of the outer bellows-joint 46 are gas-tightly connected to the outermost end periphery of the end flange 42 and the end flange 44, respectively; the left and right ends of the inner bellows-joint 48 are gas-tightly connected to the innermost end periphery of the end flange 42 and the end flange 44, respectively. Positioning both the bellows-joints can be easily performed.
