Abstract
UN MECANISMO DE ACCIONAMIENTO DE ALABES VARIABLES DE UN MOTOR DE TURBINA DE GAS (10) COMPRENDE UNA DISPOSICION ORDENADA ANULAR DE ALABES (21) PIVOTABLES QUE ESTAN ENLAZADOS A UN MIEMBRO DE ACCIONAMIENTO ANULAR (30) POR UNA PLURALIDAD DE PALANCAS (27). CADA ALABE (21) TIENE ADEMAS UNA PALANCA DE INDICACION (31) FIJADA AL MISMO. CADA PALANCA DE INDICACION (31) COOPERA CON EL MIEMBRO DE ACCIONAMIENTO (30) DE MODO QUE, EN CONDICIONES NORMALES, DURANTE EL PIVOTAMIENTO DE LOS ALABES (21) NO TIENE LUGAR TRANSFERENCIA ALGUNA DE CARGA ENTRE ELLOS. SIN EMBARGO, EN CASO DE QUE UNO O MAS DE LOS ALABES (21) NO LLEGUEN A PIVOTAR APROPIADAMENTE, TAL TRANSFERENCIA DE CARGA TIENE LUGAR. SE HAN PREVISTO MEDIOS (37) PARA DETECTAR TAL TRANSFERENCIA DE CARGA PARA PROPORCIONAR UNA INDICACION DE TAL FALLO DE UN ALABE (21) EN CUANTO A PIVOTAR APROPIADAMENTE.
