Abstract: 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.

Abstract: 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.

Abstract: A planetary gear arrangement including a sun gear configured to rotate about an axis of rotation, a plurality of planet gears driven by the sun gear, a ring gear engaged with the plurality of planet gears and a plurality of journal pins arranged in the plurality of planet gears forming a converging gap and a diverging gap therebetween. Each journal pin has at least one longitudinal groove along an outer surface thereof, configured to guide oil on the outer surface when the oil is carried from the converging gap towards the diverging gap due to a revolving movement between a planet gear around a corresponding journal pin. A journal pin for supporting a gear and a gas turbine engine.

Abstract: The invention relates to a planetary gear box, which has a sun gear, a plurality of planet gears, a ring gear, a plurality of plain bearing pins and an axially front carrier plate and an axially rear carrier plate. The plain bearing pin and the planet gear here configure a lubricated plain bearing which includes a plain bearing gap. Furthermore, the plain bearing pin, on the contact face thereof, configures a feed pocket which is provided and configured to receive oil and during the operation deliver oil in the circumferential direction to the plain bearing by way of a delivery edge. It is provided that the feed pocket is configured in the contact face of the plain bearing pin in such a manner that the delivery edge has a profile that deviates from a straight profile parallel to the longitudinal axis of the plain bearing pin.

Abstract: A planetary gear arrangement for carrying load including a sun gear configured to rotate about an axis of rotation of the planetary gear and defines an axial direction of the planetary gear, a plurality of planet gears driven by the sun gear, a ring gear engaged with the plurality of planet gears and a plurality of elliptical pins, each having a longitudinal axis and an outside contact surface, wherein the plurality of elliptical pins are arranged in the plurality of planet gears forming a convergent gap and a divergent gap therebetween, and wherein plurality of elliptical pins are configured to conform to elliptically deformed plurality of planet gears when subjected to the load and form an effective area therebetween to bear the load. An elliptical pin for supporting a gear and a gas turbine engine.

Abstract: 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.

Abstract: 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.

Abstract: A bearing for a crusher, in particular for a gyratory crusher or cone crusher, may include a housing, an eccentric bush that is mounted in the housing such that the eccentric bush can be rotated about an axle, a bushing that is disposed between the housing and the eccentric bush, and a lubricant line for supplying the bushing with lubricant that extends into the eccentric bush. The lubricant line may extend along an axial direction within a wall of the eccentric bush. An outer side of the eccentric bush may have an outlet opening for the lubricant line, with the outlet opening being directed onto the bushing.
