Abstract

LA INVENCION SE REFIERE A UNA JUNTA PARA MECANISMO DE TURBOACCIONAMIENTO EN LA ZONA DE LAS PUNTAS DE LOS ALABES DEL ROTOR CON UN ANILLO (5) DE BANDA DE COBERTURA SOBRE LAS PUNTAS DE LOS ALABES Y SEGMENTOS DE ANILLO DE CUBIERTA FIJOS, COLOCADOS DE FORMA OPUESTA, PARA ESTANQUEIDAD DE UN ESPACIO ENTRE EL ROTOR Y EL ESTATOR. EL ANILLO DE BANDA DE CUBIERTA MUESTRA DE FORMA RADIADA HACIA AFUERA UNA SUPERFICIE (9) DE ANILLO DE BANDA DE CUBIERTA, NO ESTANDO UNIDO DE FORMA INTEGRAL CON LOS ALABES. A PARTIR DE LOS SEGMENTOS DE ANILLO DE CUBIERTA FIJOS DE LA CARCASA SE ELEVAN RADIALMENTE HACIA EL INTERIOR ELEMENTOS (12) CONSTRUCTIVOS ELASTICOS, QUE CONFIGURAN LAS SUPERFICIES DE ROZADURA. LAS TOLERANCIAS DE EXCENTRICIDAD Y LA RUGOSIDAD DE LA SUPERFICIE DE ANILLO DE BANDA DE CUBIERTA EXTERIORES RADIALES, QUE DETERMINAN LA ELASTICIDAD DEL ELEMENTO CONSTRUCTIVO Y LA MAGNITUD DE LA SUPERFICIE DE ROZADURA DE CADA ELEMENTO CONSTRUCTIVO, SON DETERMINADAS DE TAL MODO, QUE RESULTA UNA VELOCIDAD RELATIVA CRITICAENTRE LA SUPERFICIE DE ANILLO DE BANDA DE CUBIERTA EXTERIOR RADIAL Y LA SUPERFICIE DE ROZADURA CON UN DESLIZAMIENTO AERODINAMICO DE LAS SUPERFICIES DE ROZADURA SOBRE LAS SUPERFICIES LISAS DEL ANILLO DE BANDA DE CUBIERTA.
