Abstract

Patente de Invenção:<B>"RETENTOR E CONJUNTO DE VEDAçãO DE INTERESTáGIO"<D>. Um retentor (82) que, em uma modalidade exemplificadora da invenção, é usado em um conjunto de vedação de interestágios do motor de turbina a gás para reter um flange (50) de um anel de vedação anular de um anel de vedação (48) contra um flange (60) da plataforma anular que se estende radialmente para dentro de uma plataforma interna (30) de um estágio (36) do bocal anular dotado de cataventos do bocal (26). O retentor inclui um corpo (90) dotado de uma parte central (92) através da qual um furo (88) é formado ao redor de um eixo geométrico do furo (89) e uma aba central (94) se estende radialmente para fora da parte central (92) com relação ao eixo geométrico do furo (89). Os primeiro e segundo braços (97 e 98), respectivamente, se estendem nas primeira e segunda direções tangenciais respectivas opostas (100 e 102), com relação ao eixo geométrico do furo (89), longe da parte central (92) e um do outro. Espaçadores axiais (104) que estendem posteriormente das primeira e segunda extremidades livres (106 e 108) dos primeiro e segundo braços (97 e 98), respectivamente, e os pés anti-rotação (105) com as extremidades arredondadas (109) dependem das primeira e segunda extremidades livres (106 e 108) em uma direção oposta a partir da qual a aba central (94) se estende. Um conjunto de pedestal (110) estende-se posteriormente da parte central (92) e está localizada após a aba central. Na modalidade exemplificadora, o conjunto de pedestal (110) tem uma superfície interna cilíndrica semi-anular (114) e uma superfície externa cilíndrica semi-anular circunscrita ao redor do eixo geométrico do furo (89), em que a superfície externa cilíndrica semi-anular (116) estende-se entre superfícies geralmente paralelos afastados radialmente interno e externo (120 e 122), respectivamente, com relação ao eixo geométrico do furo (89), e as superfícies radialmente internas (120) são coplanares e as superfícies radialmente externas (122) são coplanares. Chanfros (132) são formados ao longo das superfícies radialmente internas e externas (120 e 122), respectivamente. O retentor (82) é uma unidade fundida integralmente que inclui o corpo (90), a parte central (92), a aba central (94), os primeiro e segundo braços (97 e 98), os espaçadores axiais (104), os pés anti-rotação (105) e o conjunto de pedestal (110).
