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.

Abstract: A bearing assembly for rotatably supporting a first carrier element on a second carrier element includes first and second parts, each having a through-bore, configured to rotate about a common axis, and a first fastener for attaching the first part to the first carrier element and a second fastener for attaching the second part to the second carrier element. The first and the second through-bores are aligned with each other, and the second fastener is configured to pass entirely through the first through-bore into the second through-bore and engage an interior of the second through-bore to fasten the second part to the second carrier element. The first fastener is too large to pass entirely through the first through-bore and is configured to engage an interior of the first through-bore to fasten the first part to the first carrier element.

Abstract: A device for cleaning a surface of a component includes a high voltage source having a cathode configured to be electrically connected with the surface of the component. An ionization electrode includes at least one individual electrode configured to be electrically connected with an anode of the high voltage source. A movable carriage moves the ionization electrode relative to the surface of the component so that an electric field generated between the ionization electrode and the surface of the component is also moved relative to the surface of the component.
