Abstract

Perfeccionamientos en dispositivos para la limitación de fuerza axial, especialmente para órganos de cierre, con accionamiento motórico de una tuerca de husillo con el fin de desplazar longitudinalmente a un husillo roscado enroscado en la tuerca, con elementos elásticos que ceden en la dirección axial del husillo roscado, así como con interruptores final de carrera para limitar la carrera del husillo, caracterizados por una tuerca alojada desplazable axialmente por dos aros de cojinete desplazables axialmente y solicitados por resortes, con superficies cónica cóncavas que se miran, que forman conjuntamente un intersticio en cuña anular y alojan a elementos fiadores, por una ranura anular en la tuerca destinada a actuar conjuntamente con los elementos fiadores, así como por una unión por forma, fija al giro y que permite un desplazamiento axial de la tuerca y la rueda de accionamiento.
