Abstract

ALOJAMENTO DE SUPORTE DE MANCAL E APARELHO DE MANCAL DE UM MOTOR DE TURBINA A GÁS. A presente invenção refere-se a mancais usados em motores de turbina a gás, e mais particularmente a um suporte de mancal para montar um mancal de elemento rolante em um motor de turbina a gás. O alojamento de suporte de mancal (36) para um motor de turbina a gás, compreendendo, em sequência radial a partir de um centro para fora: um anel interno (50) que define um furo central (46); um anel médio (58) que inclui uma matriz de fendas internas (60), uma trama externa (62) que inclui uma matriz de fendas externas (64), em que as fendas internas e externas são posicionadas, dimensionadas e conformadas de modo a dividir o anel médio (58) e a trama externa (62) em uma matriz de vigas que se estendem tangencialmente (70) e escoras internas e externas que se estendem radialmente; e um anel externo (66).
