Abstract

APARATO Y METODO PARA MEDICION A DISTANCIA DE ALABES. APARATO PARA MEDICION A DISTANCIA DE ALABES QUE COMPRENDE UN PRIMER MEDIO (28) PARA PROPORCIONAR UNA INDICACION DE LA POSICION ANGULAR INSTANTANEA DEL ROTOR CON RESPECTO A UNA POSICION DE REFERENCIA, Y UN SEGUNDO MEDIO (34) PARA PROPORCIONAR UNA INDICACION ALREDEDOR DEL ROTOR. UN TERCER MEDIO (24) ESTA ACOPLADO OPERATIVAMENTE Y ES SENSIBLE A LAS INDICACIONES PROVISTAS POR LOS MEDIOS PRIMERO Y SEGUNDO PARA PROPORCIONAR UNA INDICACION DE LA POSICION ANGULAR DE CADA ESPIGA Y CALCULAR EL PASO DE ALABES. SE REVELA TAMBIEN UN METODO DE MEDICION DEL PASO DE ALABES.
