ABSTRACT:
A multi-speed planetary gear transmission having a primary shaft connected to a secondary shaft via a planetary gear having a drive annular gear connected to one of said shafts, a planet carrier connected to the other shaft, and planet gears on the carrier, each having a plurality of gearings of different diameters, and the remaining annular gears other than the drive annular gear engaging the planet gearing to provide different gear steps. All annular gears have couplings with servo-motors fixed to the casing. The annular gears are made adjustable on their respective planet gearings by floating, as a result of their being supported in the casing at a support point spaced axially from its gear teeth and located in axial proximity to its coupling. An air flow path is provided across the friction disc couplings when disengaged, as a result of alternating plates being sinusoidal. The direct drive coupling includes a slidable connecting sleeve. Oil is fed from the central shaft to lubricate the planet gear teeth and bearings. The servo-motor pistons have seals which permit their tilting within their respective cylinders. The engaging gears may be constructed in different ways to adapt to sagging of the planet gears.
