Claim Text:
1. A planetary drive, comprising: a central axis; a first set of first planet gears on a planet carrier arranged at a radial distance from the central axis; a first center gear having the central axis as its axis of rotation, each first planet gear having a toothed engagement with the first center gear; a pin having a first end mounted on the planet carrier and received on the first end by a sleeve that sits in and is supported by the planet carrier, where the pin is operatively arranged to receive each first planet gear in a manner allowing rotation about an axis of symmetry; a hole in a base of the sleeve, where the base has a first edge forming a boundary of the hole; and, an internal lubrication channel having a second edge on an end face opening and extending along the axis of symmetry of the pin, where the internal lubrication channel at least partially overlaps with the first edge thereby reducing a cross-section of the end face opening of the internal lubrication channel.
