ABSTRACT:
A transmission device comprising a first rotary element having two rolling friction surfaces which are of revolution about the axis of rotation of the element, or first axis, and having a centre of symmetry located on the first axis, the two surfaces of the first element each being in frictional contact at a single point with one or the other of two rolling friction surfaces which are of revolution about a common axis of rotation, or second axis, and have a centre of symmetry located on said second axis, the first axis and the second axis being inclined with respect to each other at an angle a and contained in the same plane, wherein the centre of symmetry of the surfaces of revolution of the first element and the centre of symmetry of the surfaces of revolution which are in contact with the first element are coincident at the same point S, the two surfaces of revolution about the second axis are formed on two parts connected to rotate with each other of a second element connected to a first shaft coaxial with the second axis, the assembly formed by the two surfaces of the second element is different from a sphere, and the first element is connected to rotate with a second shaft so that the two points of contact between the first element and second element are symmetrical with respect to the common centre of symmetry and therefore located on each side of the second axis and first axis.
