Abstract

LA INVENCION TRATA DE UNA DISPOSICION DE JUNTA EN UN EJE DE UNA MAQUINA SITUADO POR MEDIO DE AL MENOS UN LUBRICANTE DE ACEITE DEL RODAMIENTO, CUYA DISPOSICION CONTIENE UNA JUNTA DE LABERINTO (8) EN CUYO LADO DE ENTRADA, ENTRE UNA PIEZA QUE ROTA Y UN BORDE ANULAR (9), FORMADO EN LA JUNTA DE LABERINTO (8) SE FORMA UNA HENDIDURA DE ENTRADA RADIAL, EN CUYA DISPOSICION SE PREVEEN ESCALONAMIENTOS (14, 20) QUE FORMAN BORDES ROCIADORES CON CHORRO, CUBIERTOS DESDE LAS CAMARAS (13, 18, 19) QUE SE FORMAN EN EL CUERPO DE LA JUNTA DE LABERINTO, LEJANO AL EJE (3), Y CUYOS DIAMETROS DE DICHOS ESCALONAMIENTOS CRECEN HACIA LA HENDIDURA DE SALIDA DE LA JUNTA DE LABERINTO Y EN LAS CUALES LAS CAMARAS (13, 18, 19) SE COMPONEN DE UNA SALIDA DE DESAGUE (15). UN ESTANCAMIENTO DESARROLLADO CON UN CUERPO DE JUNTA DE LABERINTO DE UNA SOLA PIEZA ES POSIBLE DE FORMA QUE SE PREVEA UN SALIENTE DEL DEPOSITO (7) PRECOLOCADO RADIALMENTE EN EL LADO QUE VUELVE DE LA JUNTA DE LABERINTO EN EL ANILLO INTERIOR (6) DEL RODAMIENTO(4), QUE FORMA CONJUNTAMENTE CON EL REBORDE ANULAR (9) LA HENDIDURA DE ENTRADA RADIAL Y QUE SITUAN LA HENDIDURA DE ENTRADA Y SALIDA (10 Y 21) A UN DIAMETRO IGUAL O AL MENOS PARECIDO.
