Abstract

LA INVENCION SE REFIERE A UN DISPOSITIVO (10) DE AJUSTE CON PROTECCION DE SOBRECARGA CONSISTIENDO EN UN ACCIONAMIENTO (12) CONTROLABLE CON UN EJE (14) DE HUSILLO INTEGRAL EN ROTACION, CON AL MENOS UN COMPONENTE DE CONTACTO DIRECTO EN EL ENGRANE CON EL HUSILLO INDICADO Y CON UN CARRO MOVIL DE FORMA LINEAL SOPORTADO EN EL. DE AQUI, EL COMPONENTE DE CONTACTO DIRECTO CONSISTE PREFERENTEMENTE EN DOS RUEDAS (20,22) HELICOIDALES DISPUESTAS SOBRE EL OTRO LADO Y CON ENGRANE CON EL EJE (14) DE HUSILLO. LAS RUEDAS HELICOIDALES ESTAN FIJADAS DE FORMA ROTATIVA EN EL CARRO (16) GUIADO LONGITUDINALMENTE, Y SE DISPONE DE UN DISPOSITIVO DE PROTECCION DE SOBRECARGA LOCALIZADO A EL, POR MEDIO DEL CUAL LAS RUEDAS (20,22) HELICOIDALES GIRAN CUANDO SE PRODUCE UN PAR DE SOBRECARGA AJUSTABLE Y SUJETAN EL CARRO (16). CONJUNTAMENTE CON EL EJE LONGITUDINAL GEOMETRICO DEL EJE (14) DE HUSILLO, LAS RUEDAS (20,22) HELICOIDALES FORMAN PREFERENTEMENTE UN PLANO, MIENTRAS QUE SUS EJES DE ROTACION DESCANSAN SOBRE UN PLANO PERPENDICULAR AL EJE LONGITUDINAL DEL HUSILLO (14). ESTE DISPOSITIVO NUEVO DE ACCIONAMIENTO LINEAL ESTA CONSTRUIDO TANTO DE FORMA SIMPLE COMO ECONOMICA Y SUMINISTRA UNA ESTRUCTURA SOLIDA COMPLETA MIENTRAS QUE, ADICIONALMENTE, ASEGURA EL FUNCIONAMIENTO PROPIO A SATISFACCION DE LOS REQUERIMIENTOS DE SEGURIDAD EN TODOS LOS ASPECTOS. ADICIONALMENTE, SU DISEÑO ES EXTREMADAMENTE BAJO Y ES POR TANTO ADECUADO PARTICULARMENTE PARA ELEVADORES DE ESCALERA.
