An epicyclic gear (1) comprises a sun wheel (2) having two tooth paths, at least three planet wheels (3), rotatably arranged in a planet carrier (5) and having two tooth paths, an outer ring wheel (6) with an inner gear ring having two tooth paths (6a, 6b), and a roller ring (10) which is arranged at the inside of the ring wheel between the two paths of the inner gear ring and provided with an inner cylindrical path against which the planet wheels are arranged to abut by means of a surface (9) which is provided between the tooth paths of the planet wheels. To permit the epicyclic gear (1) to absorb all transverse forces in an efficient way during all operational situations, the cylindrical inner path of the roller ring is constructed in such a way that it forms a continuous support path (11a, 11b) for the planet wheels, which path extends along the total inner periphery of the roller ring. |
