Abstract

LA INVENCION SE REFIERE A UN INTERRUPTOR DE FIN DE CARRERA CONTENIENDO UNA CUBIERTA, UN ELEMENTO INTERRUPTOR CONTENIDO EN ESTA, UN EJE DE ROTACION, UN SISTEMA DE COJINETES QUE SOPORTA EL EJE ROTATORIO, UN BRAZO DE RODILLO, ASEGURADO A UN TERMINAL DEL EJE DE ROTACION PARA CONDUCCION DEL EJE, UNA PARTE EXCENTRICA FORMADA EN EL OTRO TERMINAL DEL EJE DE ROTACION Y UN BRAZO MOVIL Y UN BRAZO MOVIL AUXILIAR, A TRAVES DEL QUE EL ELEMENTO DE INTERRUPCION ES CONDUCIDO POR LA PORCION EXCENTRICA, DONDE EL EJE DE ROTACION TIENE MEDIOS PARA EL DEPOSITO DE GRASAS, DISPUESTOS AXIALMENTE EN SU PERIFERIA PARA LUBRICAR LAS SUPERFICIES DESLIZANTES DEL EJE DE ROTACION Y EL SISTEMA DE COJINETES. LA INVENCION PROPORCIONA UN METODO DE FABRICACION DE UN EJE DE ROTACION CON INTERRUPCION DE FIN DE CARRERA, QUE COMPRENDE LA FUNDICION A PRESION DE UN EJE DE ROTACION, UTILIZANDO UN TROQUEL PARTIDO, QUE CONSTA DE UN SEGMENTO SUPERIOR Y UN SEGMENTO INFERIOR, QUE SE CONFIGURAN PARA FORMAR UNA PAREJA DE AREAS PLANAS EXTENDIDAS, QUE SIRVEN COMO DEPOSITO DE GRASAS A LO LARGO DE SU JUNTA Y MULTIPLES VALLES Y CRESTAS PARA UNA LUBRICACION MEJORADA EN LA SUPERFICIE PERIFERICA DEL EJE ROTATORIO.THE INVENTION REFERS TO AN END OF LIMIT SWITCH CONTAINING A COVER, A SWITCHING ELEMENT CONTAINED IN IT, A ROTATING AXLE, A BEARING SYSTEM THAT SUPPORTS THE ROTATING AXLE, SECURED TO A ROLLER END. FOR AXIS DRIVING, AN ECCENTRIC PART FORMED AT THE OTHER TERMINAL OF THE ROTATION AXIS AND A MOBILE ARM AND AN AUXILIARY MOVING ARM, THROUGH WHICH THE INTERRUPTION ELEMENT IS DRIVEN BY THE EXCENTRIC PORTION, WHERE THE ROTATION AXIS IS THE FAT TANK, AXIALLY ARRANGED AT ITS PERIPHERY TO LUBRICATE THE SLIDING SURFACES OF THE ROTATION SHAFT AND THE BEARING SYSTEM. THE INVENTION PROVIDES A METHOD OF MANUFACTURING A ROTATION AXIS WITH END OF LIMIT SWITCH, WHICH INCLUDES CASTING PRESSURE OF A ROTATION AXIS, USING A SUPERIOR SEGMENT AND A LOWER SEGMENT, WHICH ARE CONFIGURED TO FORM A COUPLE OF EXTENDED FLAT AREAS, WHICH SERVE AS A FAT DEPOSIT ALONG THEIR JOINT AND MULTIPLE VALLEYS AND CRESTES FOR IMPROVED LUBRICATION ON THE PERIPHERAL SURFACE OF THE ROTATING AXIS.
