Abstract

A device, in a continuously variable belt transmission system, for guiding a conical pulley (3) of a variator on a variator shaft (1). The moveable conical pulley (3) is fitted onto two bearing sections (4, 5) of the variation shaft (1). At least one cylindrical pin (6), which is fitted into an axial guide grove (7) in the variator shaft (1) and an axial guide groove (8) of the movable conical pulley (3), is provided to transfer torque between the movable conical pulley (3) and the variator shaft (1).
