Abstract

Per un albero ad eccentrici 2, che deve essere in special modo utilizzato per l'azionamento di presse ad eccentrico, le quali sono equipaggiate con una o più bielle 17 di volta in volta mosse da un corpo di eccentrico 6/10, viene proposto un dispositivo 15 di regolazione della corsa. Ciascun corpo di eccentrico 6/10 viene formato da un eccentrico d'albero 6 e da una bussola di eccentrico 10 che abbraccia questo, i quali, per variare l'eccentricità 16 risultante del corpo di eccentrico 6/10, possono essere fatti ruotare l'uno relativamente all'altro senza soluzione di continuità, nonché possono essere reciprocamente fissati in qualsiasi arbitraria posizione angolare l'uno rispetto all'altro esclusivamente mediante un accoppiamento 20 di coppia con vincolo per attrito. Il dispositivo 15 di regolazione della corsa è caratterizzato dal fatto che la bussola di eccentrico 10 reca perlomeno su un lato un pezzo di prolungamento 18 che è unito con questa in modo da essere solidale nella rotazione, ha forma di manicotto nonché è disposto ed eseguito concentricamente al suo foro 11, e dal fatto che esclusivamente questo pezzo di prolungamento 18 forma l'accoppiamento amovibile 20 di coppia con vincolo d'attrito tra la bussola di eccentrico 10 e l'eccentrico d'albero 6 rispettivamente un prolungamento 19 dell'eccentrico d'albero. Al riguardo la figura 1.
