Abstract: The power transmission comprises two sets of epicyclic gears, there being two transmissions of rotation, either directly or through intermediate gearing, between the sets. In one configuration, input is applied by rotation of shaft 9 causing rotation of the planet carrier 4 of a first gear set, thereby transmitting power through the movement of the planet gears, such as 3, and causing the rotation of sun gear 1 and ring gear 2, these rotations being transmitted directly and respectively to sun gear 5 and ring gear 6 of a second gear set, with the subsequent motion of the planet gears, such as 7, causing rotation of the planet carrier 8 and output shaft 10. A brake 11 is preferably provided to give a fixed ratio when necessary. The transmission of rotations between the trains is alternatively provided through gearing such as a bevel gear or step up or step down gearing. The input, output and rotation transmission may be to various other elements of the gear sets. <IMAGE>
