Abstract

resumo patente de invenção: "conexão de pá para um rotor de turbina". a presente invenção refere-se a uma conexão de pá para um rotor da turbina (1) onde o rotor da turbina (1) inclui uma série de pás (4) cercando um disco central (2), onde pelo menos uma pá (4) está giratoriamente ou articuladamente ligada ao disco central (2), e onde a posição da pá (4) com relação ao disco central (2) em funcionamento é definida por um encosto (22) entre a pá (4) e um suporte (16), onde o suporte (16) está ligado ou constitui uma parte do disco central (2), e onde o suporte é constituído por uma superfície de encosto (18) sobre o suporte (16) e uma superfície de encosto (20) na pá (4), onde a superfície de encosto (18) no suporte (16) é não-plana, no sentido de que é fornecida com um encurvamento (19), e que a superfície de encosto (20) da pá (4) é fornecida com um encurvamento (21) adaptada para se encaixar na encurvamento (19) da superfície de encosto (18) do suporte (16), de acordo com o qual encosto (22) é adaptado para acomodar as forças que atuam, tanto de forma tangencial e radial sobre a pá (4).
