Abstract

UNA CONEXION IMPULSORA ENTRE UN EJE DE ELEVAS HUECO (1) Y SU EJE DE TRANSMISION (5) SITUADO DENTRO DEL MISMO, SIENDO LOS EJES (3,8) DE ESTOS DOS ELEMENTOS PARALELOS PERO LATERALMENTE DESPLAZABLES PARA VARIAR LAS CARACTERISTICAS DE ROTACION DEL EJE DE ELEVAS EN RESPUESTA A UNA ROTACION DE VELOCIDAD CONSTANTE DEL EJE DE TRANSMISION. EL EJE DE ELEVAS SOPORTA UNA VIA DE DESLIZAMIENTO (11) EN DONDE SE MUEVE UNA CORREDERA (12) QUE FORMA UNA JUNTA GIRATORIA CON EL EXTREMO DE UN BRAZO (15) SOPORTADO POR EL EJE DE TRANSMISION. LA GEOMETRIA DEL BRAZO ES TAL QUE EL CENTRO DE ROTACION (18) DE LA JUNTA GIRATORIA ESTA SITUADO DENTRO DEL CONTORNO DE LA PERIFERIA DEL EJE DE TRANSMISION (5) CUANDO SE MIRA A LO LARGO DE SU EJE (8), CON LO QUE SE PROPICIA LA COMPACTICIDAD RADIAL. EL COMPONENTE ESENCIAL DEL BRAZO PUEDE SER UNA PIEZA (15) DE SECCION TRANSVERSAL EN SEMILUNA, CUYA SUPERFICIE CONCAVA (19) COINCIDE CON LA SUPERFICIE DEL EJE DE TRANSMISION.
