US 7,608,005 B2 · Planet carrier

Abstract

The invention relates to a planet carrier (1) with planet pins (2) that are supported in at least one wall section (10) of the planet carrier (1), the planet carrier (1) having at least one axial bearing (6) supported on the wall section (10), with the axial bearing (6) being supported on the wall section (10) by means of at least one axial disc (9), the planet carrier (1) furthermore having at least one lubricating oil feed (11) overlapping the planet pins (2) to the planet pins (2), with the lubricating oil feed (11) having at least one oil retaining disc (13, 22) located on the planet carrier (1) and thus overlapping the lubrication openings (12) to the hollow planet pins (2).

Dependent claims

A planet carrier comprising a housing having at least one wall section with an opening therein;

an axial disc mounted in the opening, the axial disc having an annular disc-shaped axial roller track, the track supported by the wall section and an axial roller bearing with roller bodies rolling on the track, wherein the axial disc projects axially outwards from the wall section in an adjacent manner to the annular disc-shaped axial roller track, so that an annular gap is formed axially in an adjacent manner to the annular disc-shaped axial roller track between the wall section and the axial disc, with at least one oil retaining disc dipping at least partially radially into the annular gap.

Dependencies are inferred from the claim text.
