A ring gear mounted for rotation and driven by a pinion which dips into an oil bath is provided on each face with a sealing device. Each sealing device has a conical annulus tapering in a direction away from the ring gear and on which a ring is positioned in spaced relation with the gear. There thus is formed between the gear and each ring an annular oil collecting chamber which leads oil carried upwards by the ring gear back into the oil bath.
