Abstract

Dispositivo per innesto tra alberi meccanici con molla elicoidale posta attorno a due cilindri solidali ai due alberi, con estremità agganciate a due collari che circondano tale molla con un anello con alette radiali triangolari che, con moto assiale inserendosi o disinserendosi tra rilievi nel primo collare e denti sul secondo collare, ne determina la rotazione in senso opposto per lo svolgimento o l'avvolgimento della molla e quindi per determinare l'aderenza o meno a tali cilindri.Device for coupling between mechanical shafts with helical spring placed around two cylinders integral with the two shafts, with ends hooked to two collars that surround this spring with a ring with triangular radial fins which, with axial motion, inserting or disengaging between reliefs in the first collar and teeth on the second collar, determines their rotation in the opposite direction for unwinding or winding the spring and therefore for determining whether or not they adhere to these cylinders.
