Abstract

1. Combinazione di giunto di accoppiamento/freno azionabile elettromagneticamente.2.1 Nelle note combinazioni di giunto di accoppiamento/freno, nelle quali un'ancora a disco è spostabile avanti e indietro assialmente fra una flangia di accoppiamento e una flangia di freno, per il caso in cui l'albero da trascinare attraverso l'ancora a disco debba essere fissato per motivi di sicurezza, addizionalmente alla disposizione di elettromagnete associata alla flangia del freno deve anche essere previsto un freno di sicurezza separato. Ciò è dispendioso.2.2 Viene proposto di associare al mozzo nonché all'ancora a disco supportata nella sua posizione iniziale da una membrana una disposizione di molle agente contro la superficie di attrito della flangia del freno, la cui forza di compressione è inferiore alla forza assiale dell'elettromagnete, ma è sufficiente per il fissaggio dell'ancora a disco alla flangia del freno. In tal modo un freno di sicurezza può venire integrato entro la combinazione di giunto di accoppiamento/freno, senza ingombro addizionale.2.3 Impiego per azionamenti di macchine.3. Disegno.1. Combination of electromagnetically actuated coupling / brake coupling. 2.1 In the known coupling / brake coupling combinations, in which a disc anchor can be moved axially back and forth between a coupling flange and a brake flange, for the case in which the shaft to be dragged through the disk anchor must be fixed for safety reasons, in addition to the arrangement of the electromagnet associated with the brake flange, a separate safety brake must also be provided. This is expensive.2.2 It is proposed to associate to the hub as well as to the disc anchor supported in its initial position by a membrane an arrangement of springs acting against the friction surface of the brake flange, whose compressive force is less than the axial force the electromagnet, but it is sufficient for fixing the disk anchor to the brake flange. In this way, a safety brake can be integrated into the coupling / brake coupling combination, without additional bulk. 2.3 Use for machine drives. 3. Drawing.
