Title (EN) FRICTION WHEEL DEVICE FOR TRANSMITTING,WITH A CONTINUOUSLY VARIABLE SPEED RATIO,A ROTARY MOTION BETWEEN TWO COAXIAL SHAFTS
(FR) DISPOSITIF A ROUES DE FRICTION POUR TRANSMETTRE, AVEC UN RAPPORT DE VITESSE VARIABLE DE MANIERE CONTINUE, UN MOUVEMENT ROTATIF ENTRE DEUX ARBRES COAXIAUX
Abstract: front page image
(EN)On a drive shaft (1) there is mounted a drive member (2) which is integral in rotation with this shaft, but radially and axially displaceable; a disk (3) is rotatingly mounted on the driving member (2) through a roller bearing (21) and carries a friction ring (4) presenting four conical transmission surfaces (30, 31). The transmission surfaces (30) of the friction ring (4) roll on the transmission surfaces (33) of two friction crowns (7, 8) of a friction wheel (6) integral with the casing and the transmission surfaces (31) roll on transmission surfaces (34) of two friction crowns (10, 11) of a second friction wheel (9) mounted on the driven shaft (12), concentrically to the friction wheel (6). The spacing of the friction crowns (7, 8) respectively (10, 11) is variable. During the rotation of the driving shaft (1) the friction ring (4) effects a slow oscillating motion about the driving shaft (1) and transmits this motion to the frictional wheel (9). The two transmission fields are onset by 180 . The excentricity is adjustable between a maximum and O, which allows a reduction up to the infinite.
(FR)Sur un arbre d"entrainement (1) est monte un organe d"entrainement (2) qui est solidaire en rotation de cet arbre, mais deplacable radialement et axialement; un disque (3) est monte a rotation sur cet organe d"entrainement (2) par l"intermediaire d"un palier a roulement (21) et porte un anneau de friction (4) presentant quatre surfaces de transmission coniques (30, 31). Les surfaces de transmission (30) de l"anneau de friction (4) roulent sur des surfaces de transmission (33) de deux couronnes de friction (7, 8) d"une roue de friction (6) solidaire du boitier et les surfaces de transmission (31) roulent sur des surfaces de transmission (34) des deux couronnes de friction (10, 11) d"une deuxieme roue de friction (9) montee sur l"arbre entraine (12), concentriquement a la roue de friction (6). L"espacement des couronnes de friction (7, 8) respectivement (10, 11) est variable. Lors de la rotation de l"arbre d"entrainement (1), l"anneau de friction (4) accomplit un lent mouvement oscillant autour de l"arbre d"entrainement (1) et transmet ce mouvement a la roue de friction (9). Les deux domaines de transmission sont decales de 180 . L"etendue de l"excentricite est reglable entre un maximum et zero, ce qui permet de realiser une demultiplication jusqu"a l"infini.
