Abstract

A transmission including composite planetary gears supported by a carrier such that the planetary gears are arranged around an axis of the carrier, each planetary gear consisting of a large and a small pinion which mesh with a first and a second gear, respectively, and which have a ratio Zp.sub.1 /Zp.sub.2 equal to an integer not smaller than 2, wherein Zp.sub.1 and Zp.sub.2 represent numbers of teeth of the large and small pinions, respectively. The transmission is assembled by assembling the common second gear and the carrier supporting the planetary gears, such that the small pinion of each composite planetary gear meshes with the common second gear, and assembling the common first gear and the carrier such that the large pinion of each planetary gear supported by the carrier meshes with the common first gear.
