摘要： A planetary gearbox has a sun gear, planet gears, a ring gear and plain bearing pins. A plain bearing pin is arranged in a respective planet gear, wherein the plain bearing pin and the planet gear form a lubricated plain bearing which includes a plain bearing gap, and on its contact face, the plain bearing pin forms a feed pocket which is configured to receive oil and output it to the plain bearing. On its contact face, the plain bearing pin forms an additional feed pocket which is configured to receive oil and output it to the plain bearing, is spaced from the feed pocket in the circumferential direction, and is connected to the feed pocket such that oil from the additional feed pocket can flow on the contact face of the plain bearing pin to the feed pocket.

摘要： A friction bearing of a planetary gearbox has a first rotationally fixed component and a second component rotatably connected thereto. Oil in the region of an oil feed pocket of the first component is directed into the bearing clearance between the components. The oil is directed into the oil feed pocket via at least one first line that opens into the oil feed pocket. Oil is also directed via at least one second line into the oil feed pocket, the port region of said second line into the oil feed pocket in the circumferential direction of the bearing clearance and in the main rotation direction of the second component in relation to the first component and/or in the axial direction of the friction bearing being spaced apart from the port region of the first line into the oil feed pocket.

摘要： The invention concerns a planetary gear box, which has a sun gear, a plurality of planet gears, a ring gear and a plurality of plain bearing pins. Here, a plain bearing pin is arranged in each planet gear, wherein the plain bearing pin and the planet gear form a lubricated plain bearing, and the plain bearing pin forms a crowning at its contact face, wherein the outer diameter of the contact face decreases from a maximum outer diameter towards at least one axial end of the contact face. The crowning of the contact face is configured such that the contact face is concavely shaped adjacent to at least one axial end of the contact face or to a cylindrical region adjoining the axial end.
