Abstract

a. Perfectionnement aux transmissions à chaîne et en particulier aux profils des dentures des roues de ces transmissions. b. Transmission à chaîne, caractérisée en ce qu'elle comprend, entre les dents, un creux limité par une surface de fond arquée définie par un rayon ayant pour centre un point situé sur ladite ligne médiane, qui est espacé vers l'extérieur dudit cercle primitif, ledit rayon étant au moins égal à la somme du rayon dudit coussinet plus la moitié dudit jeu de fonctionnement ; et, une surface d'extrémité extérieure arquée s'étendant radialement vers l'extérieur à chaque extrémité de ladite surface de fond, chaque surface d'extrémité s'étendant au pourtour de ladite roue. c. Concerne les transmissions à chaîne et plus particulièrement celles des véhicules à chenille.
