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： A first seal member 21A according to a first embodiment of the present invention includes a double-structure bellows 22 in corrugated form, and vibration control means provided on the outside of the bellows 22 such as to cover part of the bellows 22. A flat portion 23 that is not in corrugated form is provided in part of the bellows 22. The vibration control means is provided in a circumferential direction on an outer surface of the flat portion 23, and made up of a ring-shaped rib 25 having a plurality of holes in a circumferential direction and weights 26 inserted in the holes provided in an outer wall of the rib 25. Natural frequency is adjusted by adjusting the number of weights 26, thereby preventing resonance between the natural frequency of the first seal member 21A and the rotational frequency of a rotor from occurring.
