A planetary gear wheel construction (1) with one or several planet wheels (2) which are bearing-mounted on a planet carrier (4), which is provided in a rotating manner in a housing (8), and an oil lubrication (12) which is formed of an oil supply (14) via a ring-shaped channel (15) in the housing (8) formed of a ring-shaped groove (16) and a distribution element (17) turning along with the planet carrier (4) which is held in said groove (16) such that it can rotate, and which is provided with a passage (18) to connect said oil channel (15) to an oil channel (19) in the planet carrier (4) which opens at a planet wheel (2), characterized in that the distribution element (17) is coupled to the planet carrier (4) by means of a loose connection (20) which makes it possible to transmit the rotational movement of the planet carrier (4) to the distribution element (17), and in that the oil channel (19) in the planet carrier (4) is connected to the passage (18) in the distribution element (17) by means of a flexible or moving oil pipe (23).

Le présent brevet porte sur une structure (1) constituée d'un ou de plusieurs pignons satellites (2) qui sont montés au moyen de paliers sur un porte-satellites (4), lequel est rotatif, est présenté dans un boîtier (8) et comporte un dispositif de lubrification (12). Ce dernier est constitué d'une alimentation en huile (14) passant par un conduit en forme d'anneau (15) dans le boîtier (8), fait d'une rainure en forme d'anneau (16) et d'un élément de distribution (17) tournant de concert avec le porte-satellites (4), qui est maintenu dans la rainure (16) afin de pouvoir tourner, et qui est doté d'un passage (18) permettant de raccorder le conduit d'huile (15) à un autre conduit d'huile (19) dans le porte-satellites (4). Ce dernier comporte une ouverture au niveau d'un pignon satellite (2) et a, comme caractéristiques particulières, ce qui suit : 1) l'élément de distribution (17) est couplé au porte-satellites (4) au moyen d'une connexion lâche (20), ce qui permet la transmission du mouvement de rotation du porte-satellites (4) à l'élément de distribution (17); 2) le conduit d'huile (19) présent dans le porte-satellites (4) est connecté au passage (18) de l'élément de distribution (17) au moyen d'une canalisation d'huile flexible ou mobile (23).
