ABSTRACT:
A planetary gear set lubricating unit which supplies oil from inside a component adjacent the planetary gear set, via a radial bore and an oil catcher, axially through a bore of a planetary gear bolt to planetary gear bearings. The oil catcher forms a ring-shaped chamber, which can be filled with lubricant, and is arranged beside the planetary carrier approximately over the reference diameter of the planetary bolt. The oil catcher has outlet pipes extending axially to direct oil in the chamber. The oil catcher has ovular radial protrusions arranged such that a maximum radial dimension is close to the bolts and a minimum radial dimension is arranged between adjacent planetary bolts. The radially inner edge of the axial bore of the planetary bolts is radially located between the minimum and maximum dimensions of the protrusions. The chamber is delimited by a cover plate and a gasket.
