A lubricating device for a planetary transmission includes a planetary carrier including two carrier webs, a bearing pin arranged on the carrier webs, a bearing arranged on the bearing pin, a planetary gear mounted via the bearing, and two thrust plates arranged on either side of the planetary gear. One of the carrier webs includes a first channel-like depression arranged on a surface facing the planetary gear and arranged to feed a lubricant from radially outside of the thrust plate to the bearing. The other carrier web includes a second channel-like depression arranged on a surface facing the planetary gear and arranged to discharge the lubricant from the bearing radially outside. The first depression is arranged offset and radially further inward than the second depression such that the lubricant flows via the first channel-like depression, axially through the anti-friction bearing, and is drained via the second channel-like depression.
A lubricating device for a planetary gear bearing of a planetary transmission with a planetary carrier comprising two carrier webs, at least one bearing pin arranged on the carrier webs, an anti-friction bearing arranged on the bearing pin, a planetary gear mounted via the anti-friction bearing and two thrust plates which are arranged on both sides of the planetary gear between the planetary gear and the carrier web, wherein at least one channel-like depression is introduced on at least one carrier web in the surface facing the planetary gear, via which depression a lubricant fed from radially outside the thrust plate can be fed to the bearing region in the region between the thrust plate and the carrier web or a lubricant which flows out of the bearing region can be discharged radially to the outside in the region between the thrust plate and the carrier web, wherein on the two carrier webs only one channel-like depression is provided, wherein the depressions are arranged offset about the axis of the bearing pin and the one depression is disposed radially further inward in relation to the axis of rotation of the planetary transmission than the other depression, such that the lubricant flows via the radially further inward depression into the anti-friction bearing, flows axially through same and flows into the radially further outward depression, via which it is drained.
