Abstract

UN SELLAJE DE LABERINTO MECANICO PARA ROTAR EJES QUE TIENE ELEMENTOS DE ANILLO PRIMEROS Y SEGUNDOS. EL PRIMERO (20), INCLUYE UNA SERIE DE SURCOS Y REBORDES QUE SE EXTIENDEN AXIALMENTE ANULARES (21). EL SEGUNDO (30) ESTA ADAPTADO PARA LA INSERCION EN DICHO PRIMER ELEMENTO (20) CON UNA PLURALIDAD DE SURCOS Y REBORDES DE EXTENSION INTERNA COMPLEMENTARIOS (31) PARA FORMAR UN SELLAJE BIEN CONOCIDO DE LABERINTO. EXISTE UNA RANURA O CANAL (70) A TRAVES DEL LABERINTO QUE CONECTA LA ATMOSFERA EXTERIOR CON EL INTERIOR DEL ENSAMBLAJE DE SELLAJE. EL SEGUNDO ELEMENTO (30) ESTA ADAPTADO PARA ROTAR CON EL EJE (10), E INCLUYE UN RECESO ANULAR (32) CERCA DEL EJE E INTERNAMENTE HACIA LA CARCASA. EXISTE UNA PLURALIDAD DE ORIFICIOS RADIALES (22) PERFORADOS EN EL PRIMER ELEMENTO (20) PARA ESTAR EN EL LADO OPUESTO AL RECESO (32) EN DICHO SEGUNDO ELEMENTO (30), Y UNA PLURALIDAD DE ELEMENTOS DE HORQUILLA (23) QUE SE INSERTAN EN LOS ORIFICIOS (22) EN DICHO PRIMER ELEMENTO (20), Y QUE SE INSERTAN EN EL RECESO (32) DE DICHO SEGUNDO ELEMENTO (30). EL RECESO (32) ES LEVEMENTE MAYOR EN LA DIRECCION AXIAL QUE LOS ELEMENTOS DE HORQUILLA (23). ASI, EL SELLAJE PERMITE EL MOVIMIENTO AXIAL DEL EJE (10), MANTENIENDO LA INTEGRIDAD DEL SELLAJE DE LABERINTO Y DURANTE UNA CANTIDAD DE MOVIMIENTO PREDETERMINADO, Y AL ALCANZAR EL LIMITE DE DICHO MOVIMIENTO, LAS HORQUILLAS (23) ACOMODAN EL IMPULSO AXIAL DEL MOVIMIENTO DEL EJE (10). LAS HORQUILLAS(23), ESTAN HECHAS DE UN MATERIAL CON UNA LUBRICIDAD NATURAL, Y TIENEN SOLAMENTE UN CONTACTO DE PUNTA CON LAS PAREDES DEL RECESO (32), REDUCIENDO ASI LA CANTIDAD DE FRICCION Y DESGASTE EN LA ABSORCION DEL IMPULSO AXIAL.
