More Information
Summary:A lubrication system for a planetary gear comprising a sun gear rotationally fixedly arranged on a first shaft, a number of planet gears rotatably supported by planet gear bearings and a planet gear carrier rotationally fixedly arranged on a second shaft. The lubrication system comprises a lubrication passage directing lubricant from one of the shafts to the planet gear bearings. The lubrication passage comprises a first passage part extending through the planet gear carrier from an inlet opening to a first outlet opening. The first passage part further comprises a second outlet opening adapted to direct lubricant to an engagement area between the sun gear and the planet gears. The second outlet opening is located at a shorter radial distance from a rotation axis of the sun gear than the first outlet opening and a flow restrictor is arranged in the first passage part between the first and second openings.
