Abstract: A planetary transmission includes a transmission part rotatable about an axis of rotation and having a discharging region. The transmission part has an end face formed with a recess for receiving lubricant from a receiving region and discharging received lubricant to the discharging region. A covering plate covers the recess in the transmission part and has an opening in communication with the recess so that the recess is open to the outside. The opening is positioned in peripheral direction of the transmission part centrally in the covering plate and in radial direction of the transmission part proximally with respect to the axis of rotation of the transmission part The opening has an area sized smaller than a base area of the recess. A duct extends from an interior of the recess to the discharging region at a minimal distance from the axis of rotation of the transmission part.
