Abstract
In un apparecchio a chiocciole co-rotanti avente due avvolgimenti di chiocciola interfogliantesi fissati a piastre di estremità che ruotano attorno ad assi paralleli non concentrici, per produrre un moto orbitale relativo, un accoppiamento per provocare la rotazione simultanea e per migliorare la stabilità nutazionale dell'elemento a chiocciola. Nella forma di realizzazione preferita, i mezzi di riduzione della nutazione sono costituiti da un accoppiamento di tipo Oldham che impegna organi di estensione su di una delle piastre di estremità della chiocciola e azionano chiavette sull'altra rispettiva piastra di estremità. La loro disposizione angolare è ottimizzata per far si che l'accoppiamento Oldham generi durante la rotazione un carico a momento moderante in opposizione al carico a momento di rovesciamento di almeno uno degli elementi a chiocciola e migliorando perciò la stabilità nutazionale degli elementi a chiocciola. Il carico a momento di moderazione dell'accoppiamento imposto sugli elementi a chiocciola può essere alterato variando la disposizione angolare e radiale del baricentro dell'accoppiamento.
