Abstract

S'indica un gruppo d'ingranaggi per uso idraulico con una corona dentata avente n denti interni (4) e con una ruota dentata avente n-1 denti esterni (6), il cui centro è sfalsato in misura di un'eccentricità rispetto al centro della corona dentata e ruota intorno a questo, mentre la ruota dentata rotola sulla corona dentata, e su ciascun fianco (8, 9) d'ogni dente è previsto un incavo (10,11).In un siffatto gruppo d'ingranaggi deve aver luogo, senza aumento dell'usura, un effetto frenante quando il motore è privo di pressione.A tale scopo, la ruota dentata presenta una maggiorazione e ciascun incavo presenta tre tratti di curvatura successivi (16,17,18) ed inizia e termina con la stessa tangente come l'andamento indisturbato dei denti (12).Fig. 2
