Abstract

EMPAQUETADURA DE FLUIDO PARA SUPERFICIES DE APOYO DE EJES ROTATIVOS PARA MAQUINAS DINAMOELECTRICAS. CONSTA DE UN PAR DE AROS ANULARES, CADA UNO DE LOS CUALES ESTA DIVIDIDO EN DOS PORCIONES SEMICIRCULARES; DE UNA CAPA DE METAL ANTIFRICCION (12) QUE RECUBRE LA SUPERFICIE CIRCUNFERENCIAL INTERIOR DE CADA UNA DE LAS CUATRO PORCIONES SEMICIRCULARES (10A, 10B); DE UN CANAL (20, 21) DE FLUIDO EMPAQUETADOR PARA SUMINISTRAR FLUIDO AL ESPACIO EXISTENTE ENTRE EL METAL ANTIFRICCION Y LA SUPERFICIE DE APOYO DEL EJE (22); DE UNA CARCASA ANULAR (11) FORMADA POR DOS PIEZAS DE EMPAQUETADURA (11A, 11B), QUE ESTA MONTADA DE FORMA FIJA RESPECTO AL EJE ROTATIVO (22) Y DE MANERA QUE TOQUE A LAS SUPERFICIES EXTERIORES DE LOS ANILLOS ANULARES; Y DE MEDIOS FORMADORES QUE EJERCEN UNA FUERZA RADIAL HACIA DENTRO, CONTRA EL PAR DE ANILLOS ANULARES, Y UNA FUERZA AXIAL TENDENTE A FORZAR LOS DISCOS ANULARES.
