Patent number: 11187158Abstract: A gearbox assembly for a gas turbine engine comprises a planetary gearbox having at least one ring gear and at least one planet gear, which exerts a force on the ring gear in the direction of a force vector as it rolls on said ring gear; and a holding device for fastening the at least one ring gear on another structure, having a first section, which extends in the axial direction on one side of the force vector and/or of a straight-line extension thereof, and having a second section, which extends in the axial direction on the other side of the force vector and/or of the straight-line extension thereof. A gas turbine engine and a method for producing a gearbox assembly are furthermore made available.Type: GrantFiled: July 1, 2019Date of Patent: November 30, 2021Assignee: ROLLS-ROYCE DEUTSCHLAND LTD & CO KGInventors: Jonas Schwengler, David Krueger, Michael Nique

Patent number: 11085523Abstract: A planetary gearing includes a sun gear rotating about a rotation axis and driven by a sun shaft; planet gears driven by the sun gear, each planet gear having an axially forward face side and an axially rearward face side; a ring gear engaging the planet gears; and planet slide bearing pins, wherein respectively one planet slide bearing pin is arranged inside a planet gear forming a lubricated journal bearing. At an axially forward face side and/or axially rearward face side, each planet gear forms a recess that extends inside the planet gear starting from the face side, and the planet slide bearing pins respectively form one crowning at their abutment surface such that their outer diameter decreases from a maximum outer diameter to at least an axial end of the abutment surface and has a minimum at the axial end.Type: GrantFiled: November 21, 2018Date of Patent: August 10, 2021Assignees: Rolls-Royce Deutschland Ltd & Co KG, Rolls-Royce plcInventors: Michael Nique, Paul Gorenz, Christopher Campbell, Frank Wagner, Mark Spruce, Daren Ashmore

Patent number: 10816087Abstract: A planetary gearing includes a sun gear; a plurality of planet gears, a ring gear; and a plurality of planet pins, wherein respectively one planet pin is arranged inside a planet gear, and the planet pin and the planet gear form a lubricated journal bearing. The planet pin includes an axial bore and an inner surface that comprises an axially forward end and an axially rearward end. The inner diameter of the axial bore of the planet pin varies between the axially forward end and the axially rearward end of the inner surface and has a maximum at least at one axial end. The planet pins respectively form a crowning at their abutment surface such that their outer diameter decreases from a maximum outer diameter towards at least an axial end of the abutment surface, and has a minimum at the axial end.Type: GrantFiled: November 21, 2018Date of Patent: October 27, 2020Assignees: ROLLS-ROYCE DEUTSCHLAND LTD & CO KG, ROLLS-ROYCE PLCInventors: Michael Nique, Christopher Campbell, Mark Spruce

Patent number: 10767755Abstract: A planetary gearing includes a sun gear rotating about a rotation axis and driven by a sun shaft; planet gears driven by the sun gear; a ring gear engaging the planet gears; and a plurality of planet pins that respectively include an outer-side abutment surface having an axially forward end and an axially rearward end. Respectively, one planet pin is arranged inside a planet gear, and the planet pin and the planet gear form a lubricated journal bearing. At an axially forward face side and/or axially rearward face side, each planet gear forms a recess that extends inside the planet gear starting from the face side. The planet pins respectively form a crowning at their abutment surface such that their outer diameter decreases from a maximum outer diameter towards at least one axial end of the abutment surface, and has a minimum at the axial end.Type: GrantFiled: November 21, 2018Date of Patent: September 8, 2020Assignees: ROLLS-ROYCE DEUTSCHLAND LTD & CO KG, ROLLS-ROYCE PLCInventors: Michael Nique, Paul Gorenz, Christopher Campbell, Frank Wagner, Mark Spruce, Daren Ashmore
