Abstract:
(EN) In a rotating machine (1) a tip shroud (51A) of a moving blade (50) includes: a plurality of shroud outer peripheral surfaces (53A, 53B, 53C) provided in such a way that the radial direction positions thereof are positioned further toward a radially outer side, in a stepwise manner, with increasing distance from the upstream side to the downstream side; and stepped portions (54D, 54E) connecting the adjacent shroud outer peripheral surfaces (53A, 53B, 53C) to one another. The stepped portions (54D, 54E) have acute angle forming surfaces (55D, 55E) which extend toward the upstream side with increasing distance toward the radially outer side, and which are connected to upstream side end portions (53p) of the shroud outer peripheral surfaces (53A, 53B, 53C) positioned on the downstream side thereof, with an acute angle θ1 therebetween.
(FR) Dans une machine tournante (1) un carénage de bout (51A) d'une aube mobile (50) comprend: une pluralité de surfaces périphériques externes de carénage (53A, 53B,53C) disposées de telle sorte que leurs positions de direction radiale soient positionnées davantage vers un côté radialement externe, d'une manière pas à pas, avec une distance croissante du côté amont vers le côté aval; et des parties étagées (54D, 54E) reliant les surfaces périphériques externes de carénage adjacentes (53A, 53B,53C) l'une à l'autre. Les parties étagées (54D, 54E) ont des surfaces de formation d'angle aigu (55D, 55E) qui s'étendent vers le côté amont avec une distance croissante vers le côté radialement externe, et qui sont reliées à des parties d'extrémité côté amont (53p) des surfaces périphériques externes de carénage (53A, 53B,53C) positionnées sur le côté aval de celui-ci, avec un angle aigu θ1 entre celles-ci.
(JA) 回転機械(1)において、動翼(50)のチップシュラウド(51A)が、径方向位置が上流側から下流側に向かって段階的に径方向外側に位置するよう複数が設けられたシュラウド外周面(53A,53B,53C)と、隣接するシュラウド外周面(53A,53B,53C)どうしを接続する段差部(54D,54E)と、を有する。段差部(54D,54E)は、径方向外側に向かうに従って上流側に向かって延び、下流側に位置するシュラウド外周面(53A,53B,53C)の上流側端部(53p)に鋭角θ1をもって接続される鋭角形成面(55D,55E)を有する。
