ABSTRACT:
A transmission comprising a planetary gear mechanism wherein a plurality of planetary gears 6 are provided around a sun gear and meshed with the sun gear 5 and an internal gear 7 is provided outside the planetary gears and meshed with the planetary gears 6. The internal gear 7 consists of two split internal gears 7a, 7b divided by a plane perpendicular to its axial direction. Each of the plurality of planetary gears 6 consists of a large planetary gear 6a having a large diameter and small planetary gears 6b having small diameters and coaxially spline-coupled to the large planetary gear 6a in such a manner that the tooth portions thereof are positioned both sides of the large planetary gear 6a. The split internal gears 7a, 7b are meshed with the teeth of each small planetary gear 6b. The sun gear 5 is meshed with the large planetary gear 6a. An intermediate idle ring 11 is provided to each of the planetary gears 6 as a mechanism for equally distributing the load.
