Claim:
1. A planetary variator, functioning as a subsystem for a variable or reversible transmission comprising a ring wheel, two or more planets mounted around a central shaft, and a sun wheel, such that the ring wheel, the central shaft and the sun wheel form an interface with other transmission components, wherein each planet comprises a planet wheel running on a running surface of said sun or ring wheel, and a planet fork connecting the planet to said central shaft, characterized in that a continuous or a discontinuous control system is integrated in the assembly of each of the planets to ensure that the tip of a cone formed by the theoretical, non-crowned, planet wheel running surface coincides precisely with a hinge axis of the planet fork when a certain load is applied on the running surface, by locking the position of the planets on the central shaft using a screwing system integrated within the planet fork.
