Abstract
A planetary gear wheel construction with one or several planet wheels which are bearing-mounted on a planet carrier, which is provided in a rotating manner in a housing, and an oil lubrication formed of an oil supply via a ring-shaped channel in the housing formed of a ring-shaped groove and a distribution element turning along with the planet carrier which is rotatably held in the groove, and which is provided with a passage to connect the oil channel to an oil channel in the planet carrier which opens at a planet wheel. The distribution element is coupled to the planet carrier by a loose connection which makes it possible to transmit the rotational movement of the planet carrier to the distribution element, and the oil channel in the planet carrier is connected to the passage in the distribution element by a flexible or moving oil pipe.
