Abstract

LA INVENCION CONCIERNE A UNA BOMBA DE ENGRANAJES COMPUESTA DE UNA CAJA PROVISTA DE UN CANAL DE ENTRADA Y DE UN CANAL DE SALIDA Y DOS RUEDAS DENTADAS CON DENTADO EXTERIOR, CUYO COJINETE ESTA ALOJADO HERMETICO CONTRA EL PRODUCTO A TRASPORTAR EN LA CAJA. LA TAREA DE LA PRESENTE INVENCION ES REDUCIR EL DESGASTE CON MEDIOS SENCILLOS Y CONFIGURAR LA BOMBA DE ENGRANAJES DE MODO QUE TRANSPORTE SIN PERDIDA DE DURACION DE MODO PERFECTO CLASES DE MEZCLAS DE CAUCHO DE DIFICIL TRANSPORTE. LA INVENCION CONSISTE EN QUE LAS JUNTAS ESTAN DISPUESTAS EN FORMA DE UNA ESPIRAL DE TRANSPORTE PARA EL RETORNO DEL MATERIAL TRANSPORTADO A LOS LADOS FRONTALES DE LAS RUEDAS DENTADAS PARA LA SEPARACION ENTRE CAMARA DE TRANSPORTE Y ALOJAMIENTO DE LAS RUEDAS DENTADAS.
