Abstract

Courroie de transmission comprenant un corps annulaire flexible et inextensible. Elle porte, sur les deux flancs du corps annulaire, une série de plaquettes en matière à grand coefficient de frottement situées dans des plans qui convergent vers le centre dudit corps annulaire. Application aux mécanismes de transmission de mouvement à courroie et poulies où au moins l'une des poulies possède une gorge dont les dimensions diamétrales sont variables de manière à obtenir des rapports de transmission variables.Transmission belt comprising a flexible and inextensible annular body. It carries, on the two sides of the annular body, a series of plates made of a material with a high coefficient of friction situated in planes which converge towards the center of said annular body. Application to belt and pulley motion transmission mechanisms where at least one of the pulleys has a groove whose diametral dimensions are variable so as to obtain variable transmission ratios.
