Abstract

LOS COJINETES DE UN VASTAGO DE MAQUINA HERRAMIENTA ES CERRADO POR UN PAR DE CIERRES DESLIZANTE MONTADOS EN EL EJE Y ELASTICAMENTE REQUERIDOS EN CONTACTO CON LAS CARAS OPUESTAS DE UN ANILLO ESTACIONARIO A TRAVES DEL CUAL SE EXTIENDE EL EJE. EL MUY PEQUEÑO ESPACIO ENTRE EL ANILLO Y EL EJE ES ALIMENTADO CON GAS POR EJEMPLO AIRE A BAJA PRESION. CUANDO NO HAY SUMINISTRO DE GAS Y POR EJEMPLO CUANDO EL EJE ES ESTACIONARIO LOS CIERRES CONTACTAN EL ANILLO Y LA ELASTICIDAD ASEGURA EL BUEN CONTACTO Y PREVIENE LA FILTRACION DE POR EJEMPLO EL LUBRICANTE A LO LARGO DEL EJE DESDE UN LADO DE LOS CIERRES AL OTRO. CUANDO EL EJE ESTA PARA SER DIRIGIDO, EL GAS DE BAJA PRESION ES SUMINISTRADO Y ESTA PRESION DESVIA LOS CIERRES PARA ELEVARLOS DESDE LA CARA DEL ANILLO TAL QUE NO HAYA ENGRANE FRICCIONAL Y PERDIDA DE POTENCIA O GENERACION DE CALOR, Y CUALQUIER LIQUIDO QUE PASE LOS CIERRES ES TIRADO HACIA FUERA POR LA FUERZA CENTRIFUGA Y DIRIGIDO POR LOS GASES DE ESCAPE.
