Title
(EN) PLATFORM SEAL AND DAMPER ASSEMBLY FOR TURBOMACHINERY AND METHODOLOGY FOR FORMING SAID ASSEMBLY
(FR) ENSEMBLE JOINT D'ÉTANCHÉITÉ ET AMORTISSEUR DE PLATEFORME POUR TURBOMACHINE ET MÉTHODOLOGIE DE FORMATION DUDIT ENSEMBLE
Abstract
(EN)
A platform seal and damper assembly for turbomachinery (100), such as fluidized catalytic cracking (FCC) expanders or gas turbine engines; and methodologies for forming such assembly are provided. An axially-extending groove (160) is arranged on a side (162) of a respective platform. Groove (160) is defined by a radially-outward surface (168) at an underside of the platform and a surface (170) extending with a tangential component (T) toward radially-outward surface (168). A seal and damper member (152) is disposed in groove (160), where the body of seal and damper member has adjoining surfaces (190, 188) configured to respectively engage, in response to a camming action, with the surfaces (168, 170) that define the axially-extending groove. The camming action being effective to produce an interference fit of the seal and damper member (152) with the side of the respective platform (162) and an opposed side (163) of an adjacent platform.
(FR)
L'invention concerne un ensemble joint et amortisseur de plate-forme pour turbomachine (100), tels que des détendeurs de craquage catalytique en lit fluidisé (FCC) ou des moteurs à turbine à gaz ; et des méthodologies de formation d'un tel ensemble. Une rainure (160) s'étendant axialement est disposée sur un côté (162) d'une plateforme respective. La rainure (160) est délimitée par une surface radiale vers l'extérieur (168) au niveau d'une face inférieure de la plate-forme et une surface (170) s'étendant avec une composante tangentielle (T) vers la surface radiale vers l'extérieur (168). Un élément (152) d'étanchéité et d'amortissement est disposé dans la rainure (160), le corps de joint d'étanchéité et d'amortisseur ayant des surfaces adjacentes (190, 188) conçues pour venir respectivement en prise, en réponse à une action de came, avec les surfaces (168, 170) qui délimitent la rainure s'étendant axialement. L'action de came est efficace pour produire un ajustement serré du joint et de l'élément amortisseur (152) avec le côté de la plate-forme respective (162) et un côté opposé (163) d'une plate-forme adjacente.
