Abstract:
A lubricant feed system for a planetary drive to feed lubricant, which moves by centrifugal force, to bearings of planet pinions in a first set of planets on first planet shafts, one end of each of which is held in a wall of a planet carrier, and to feed the lubricant to second bearings of second planet pinions of a second set of planets separated from the first set of planets, at least in the longitudinal direction, by the wall of the planet carrier, the system comprising a first guide that guides the lubricant to the first planet shafts, at least one channel in each of the first planet shafts that passes through the wall, at least one transverse channel exiting the at least one channel and leading the lubricant to the bearings of the planet pinions of the first set of planets, and with a second guide arranged for the second set of planets, with the first set of planets being arranged upstream in a lubricant flow path from the second set of planets, whereby the first and second guides are connected via the at least one channel, so that the lubricant passes from at least one of the first guide and the at least one channel to the second guide and then to the second bearings of the second planet pinions.
