Abstract

EN UNA BARRA DE CUCHILLAS DE DOS BRAZOS (10) PARA UN CORTACESPED CON EJE GIRATORIO VERTICAL SE FIJAN LAS CUCHILLAS (14) SOBRE UN PERNO DE FIJACION (36) UNICO EN AMBOS EXTREMOS. LOS SEGMENTOS EXTREMOS DE LA BARRA DE CUCHILLAS (10) MUESTRAN CONDUCCIONES DE GIRO CONICAS (24) EN QUE SE ADAPTAN CONDUCCIONES DE GIRO CONICAS (38) CORRESPONDIENTE DE LA PLACA DE SOPORTE DE CUCHILLAS (32). ASI SE PERMITE UN CENTRAMIENTO Y CONDUCCION GIRATORIA. UNA CONEXION DE CIERRE ENTRE UNA NERVADURA (46) DE LA PLACA PORTADORA DE CUCHILLAS (32) Y UNA ACANALADURA (20) DE LA BARRA DE CUCHILLA (10) ORIGINA UN CIERRE QUE SE ELEVA EN UN SOBREESFUERZO AL ENCONTRAR UNA PIEDRA O DIMILAR DE MODO QUE PUEDE FIRARSE LA CUCHILLA (14). ESTE ELEVAMIENTO DEL CIERRE PUEDE PRODUCIRSE EN ZONA ELASTICA O PLASTICA MIENTRAS LAS PIEZAS QUE ENGRANAN UNAS EN OTRAS SON ELASTICAS, O AUMENTAN LA LONGITUD DEL PERNO POR EJEMPLO AL UTILIZAR UN PERNO DE DILATACION, CUANDO OCURRE UNA SOBRECARGA.
