A system includes a wind turbine having a fixed part and a rotational part and a brake having a brake disk mounted to the rotational part for rotation with the rotational part. At least one brake block is fixed relative to the fixed part and has a friction surface facing the brake disk. The brake block is shiftable between a first position with the friction surface spaced from the brake disk and a second position with the friction surface in contact with and pressed against the brake disk, and the friction surface and/or the brake disk are configured such that pressing the at least one brake block against the brake disk creates a micro-interference fit between the at least one brake block and the brake disk.

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.
