Abstract

Transmission à vitesse réglable comportant des premier et second éléments dont les axes de coupent et qui comportent des surfaces de roulement qui coopèrent en deux points, et un troisième élément servant de support au second. Les surfaces de roulement des second et premier éléments sont respectivement définies par un organe unique 80 et par des organes 86, 88 mobiles axialement Le rapport des rayons Rb /Rw des surfaces au niveau des points de contact varie en fonction de l'angle a d'intersection des axes 46, 82 et du déplacement axial des surfaces du premier élément. L'inclinaison du second élément est réglable afin de faire varier cet angle. Applications courantes.Adjustable speed transmission comprising first and second elements whose axes intersect and which include rolling surfaces which cooperate at two points, and a third element serving as a support for the second. The rolling surfaces of the second and first elements are respectively defined by a single member 80 and by axially movable members 86, 88 The ratio of the radii Rb / Rw of the surfaces at the contact points varies as a function of the angle a d 'intersection of axes 46, 82 and the axial displacement of the surfaces of the first member. The inclination of the second element is adjustable in order to vary this angle. Common applications.
