Abstract
Viene illustrata una disposizione di accoppiamento o di trasmissione di coppia per un sistema di applicazione di dispositivi di fissaggio o simili, in cui i rispettivi componenti configurati esternamente e configurati internamente sono dotati di una sette di scanalature e lobi di accoppiamento, curvati in modo ellittico. In entrambi i componenti configurati esternamente ed internamente, le scanalature ed i lobi sono definiti da una prima serie di superfici a curvatura ellittica che si alternano con una seconda serie di superfici a curvatura ellittica, con le rispettive superfici che si fondono in modo liscio e generalmente tangenzialmente per definire le scanalature e i lobi che si alternano su ciascun detto componente. Uno dei componenti, o il componente configurato esternamente o quello configurato internamente, preferibilmente avrà le scanalature ed i lobi su di esso generati da ellissi di dimensione sostanzialmente uguale. L'altro componente, necessariamente, avrà le scanalature ed i lobi generati da ellissi di dimensioni differenti. Ci si renderà conto, naturalmente, che le scanalature ed i lobi su entrambi i componenti configurati internamente ed esternamente possono essere generati da ellissi di dimensioni disuguali. In aggiunta, nella forma di realizzazione preferita, i centri delle varie ellissi che definiscono le scanalature ed i lobi cadono sugli apici di esagoni regolari. Inoltre, i centri per entrambe le serie di ellissi cadranno sostanzialmente sullo stesso cerchio. Vengono inoltre illustrati gli utensili che possono essere impiegati per formare entrambe le configurazioni esterna ed interna in conformità all'invenzione.
