Title (EN) MECHANISM WITH CONTINUOUS ADJUSTMENT FOR THE TRANSMISSION OF A ROTARY MOTION BETWEEN TWO COAXIAL SHAFTS
(FR) MECANISME A REGLAGE CONTINU POUR LA TRANSMISSION D"UN MOUVEMENT ROTATIF ENTRE DEUX ARBRES COAXIAUX
Abstract: front page image
(EN)A hub (2) is rigidly torsionwise attached to a leading shaft (1) but free to move axially and radially. A rotary plate (3) is arranged on said hub (2) through a ball bearing (21) and carries a ring (4) provided with four conical transmission surfaces (30, 31). The transmission surfaces (30) of the ring (4) run on surfaces (33) of two rims (7, 8) of a wheel (6) integral with the casing, and the transmission surfaces (31) ran on surfaces (34) of two rims (10, 11) of a second wheel (9) attached to the driven shaft (12) and coaxial with the wheel (6). The distance between the rims (7, 8 and 10, 11) is adjustable. When the driving shaft (1) rotates, the ring (4) effects a slow oscillation motion about the leading shaft (1) and transmits such motion to the wheel (9). The two transmission ranges are offset by 180 . The excentricity is adjustable between a maximum and zero, which allows the obtention of a reduction up to the infinite. A toothing may be provided in the transmission areas. As toothing elements, the ring (4) may be provided with sets of axially free disks and arranged on two rims, which mesh with grooves (71) provided in the surfaces (33, 34). Adjustement devices, preferably in the form of a unit assembly, are used for adjusting the rims (8, 11) and the hub (2).
(FR)Un moyeu (2) est fixe sur un arbre menant (1) de facon rigide en torsion mais pouvant se deplacer axialement et radialement. Un plateau rotatif (3) est dispose sur ce moyeu (2) par l"intermediaire d"un roulement a billes (21) et porte un anneau (4) muni de quatre surfaces de transmission coniques (30, 31). Les surfaces de transmission (30) de l"anneau (4) roulent sur des surfaces (33) de deux jantes (7, 8) d"une roue (6) solidaire du carter, et les surfaces de transmission (31) roulent sur des surfaces (34) de deux jantes (10, 11) d"une seconde roue (9) fixee sur l"arbre mene (12) et coaxiale avec la roue (6). La distance entre les jantes (7, 8, et 10, 11) est reglable. Lorsque l"arbre menant (1) tourne, l"anneau (4) execute un mouvement a oscillation lente autour de l"arbre menant (1) et transmet ce mouvement a la roue (9). Les deux gammes de transmission sont decalees de 180o. L"excentricite est reglable entre un maximum et zero, ce qui permet d"obtenir une demultiplication jusqu"a l"infini. Une denture peut etre prevue dans les zones de transmission. Comme elements de denture, l"anneau (4) peut etre muni de jeux de disques libres axialement et disposes dans deux jantes, qui engrenent avec des rainures (71) pratiquees dans les surfaces (33, 34). Des dispositifs d"ajustement, de preference sous forme d"un ensemble unitaire, servent au reglage des jantes (8, 11) et du moyeu (2).
