Abstract

La présente invention concerne un engrenage à friction comprenant au moins une surface d'entraînement, (70c, 70d) au moins une surface entraînée (71d, 71d') et, installée entre les deux, au moins un membre intermédiaire se présentant sous la forme d'un ensemble de corps de roulement (17, 18, 19) sphériques. La surface d'entraînement (70c, 70d) et la surface entraînée (71d, 71d') présentent un bombement toroïdal. Au moins deux, de préférence trois, corps de roulement (17, 18, 19) sont disposés en série aux fins de l'entraînement. Dans une variante, les corps de roulement sont montés coulissants ou pivotants, d'où la possibilité de régler les rapports et la tension initiale.
