Abstract
A planetary transmission includes first and second ring gears and a double planet with first and second gears rotatably disposed about a common shaft and arranged such that the gear teeth of the first gear of the double planet engage into the gear teeth of the first ring gear, and the gear teeth of the second gear of the double planet engage into the gear teeth of the second ring gear. The first gear of the double planet is preloaded in a clockwise direction such that the gear teeth of the first gear of the double planet are in contact with the gear teeth of the first ring gear, and the second gear of the double planet is preloaded in a counterclockwise direction such that the gear teeth of the second gear of the double planet are in contact with the gear teeth of the second ring gear.
