| description | To improve a sealing performance between a body and a segment ring.SOLUTION: A seal structure 100 comprises a plurality of brushes 10 provided on a body 2 at intervals in the axial direction of a tunnel T1 to form a seal chamber 11 between an inner peripheral surface of the body 2 and an outer peripheral surface of a segment ring 4, grease 20 that is filled in the seal chamber 11 and seals between the inner peripheral surface of the body 2 and the outer peripheral surface of the segment ring 4, and a cooling system 30 for cooling the grease 22 filled in the seal chamber 11.SELECTED DRAWING: Figure 2
【課題】胴体とセグメントリングとの間におけるシール性を向上させる。【解決手段】シール構造１００は、胴体２にトンネルＴ１の軸方向に互いに間隔を空けて設けられ胴体２の内周面とセグメントリング４の外周面との間にシール室１１を形成する複数のブラシ１０と、シール室１１に充填され胴体２の内周面とセグメントリング４の外周面との間をシールするグリース２０と、シール室１１に充填されたグリース２２を冷却する冷却システム３０と、を備える。【選択図】図２ |
