Abstract
resumo patente de invenção: "arranjo de lâmina". a presente invenção refere-se a um arranjo de lâmina (40) tendo um carregador de lâmina (56) e tendo uma ranhura de retenção (58) disposta no dito carregador de lâmina, cuja ranhura de retenção tem projeções (62) se estendendo ao longo das suas paredes laterais (60) de modo a formar rebaixamentos (64) e em cuja ranhura de retenção um número de lâminas (25, 27) é inserido de modo a formar um anel de lâmina de uma turbomáquina, em que cada lâmina (25, 27) tem, além de um aerofólio de lâmina (48) e para propósitos de fixação, uma base de lâmina (50) que engata nos rebaixamentos (64), e cada lâmina é pressionada contra as projeções (62) por um elemento (46) disposto entre a parte de baixo da base da lâmina (68) e uma base de ranhura (70) da ranhura de retenção (58). para especificar uma fixação particularmente segura, confiável, durável e de baixo desgaste que permita montagem e desmontagem particularmente simples, é estabelecido que cada elemento (46) seja de forma similar a uma placa e tem, na projeção do aerofólio de lâmina (48) na direção da base da ranhura (70), pelo menos um boleado (52, 55), disposto abaixo do aerofólio de lâmina (48), para transferir uma ação de pressionamento, e na direção longitudinal da ranhura de retenção (58), somente parte da base de lâmina (50) cujo dito elemento pressiona contra é coberta.
