Planet-carrier arrangement with an annular oil baffle plate

摘要

In a planet-carrier arrangement with an annular oil baffle plate which is fixed in a side-wall component (3) of the planet carrier (1) in a region radially outside the planet-wheel bolts (6), and extends radially inwards to such a degree that its inner edge inwardly reaches over the axial lubricating-oil channels provided on the planet-wheel bolts (6), in order to guide lubricating oil to the needle bearings (7) of the planet wheels (8), and the planet-wheel bolts (6) being fixed in the two side-wall components (2 and 3) of the planet carrier (1), the lubricating-oil channels provided on the planet-wheel bolts (6) are designed as open lubricating-oil grooves (15) which run spirally obliquely on the outer circumference (14) in the region of said channels which is not loaded by the needles of the needle bearings (7).
