Patent number: 11156267Abstract: A planetary gear with a sun wheel, a hollow wheel and a planetary carrier on which a planetary wheel is rotatably mounted. In the axial direction on a first side of the planetary carrier, the sun wheel and hollow wheel include connection areas for coupling the sun wheel and hollow wheel to rotatable or torque-proof areas of an engine. The planetary carrier has a connection area for attaching to rotatable or torque-proof areas of the engine on its opposite second side. The structural component stiffnesses of the sun wheel, planetary carrier, the hollow wheel and the planetary wheel are adjusted to each other such that, during operation they have twistings in the axial direction of the planetary gear that respectively qualitatively correspond to each other between the connection areas and side areas facing away from the connection areas due to the respectively applied torques.Type: GrantFiled: September 13, 2018Date of Patent: October 26, 2021Assignee: ROLLS-ROYCE DEUTSCHLAND LTD & CO KGInventors: Gideon Daniel Venter, Jan Schwarze

Patent number: 11131248Abstract: A planetary gearbox, a splined sleeve, a gas turbine engine with a planetary gearbox and a method for producing a torque-proof connection between a planetary carrier and a support element. The splined sleeve is formed with an outer substantially cylindrical shell surface area and an inner conical shell surface area, and is inserted between the planetary carrier and the support element for creating the torque-proof connection. The diameter of the inner conical shell surface area decreases in the axial direction, starting from an end of the splined sleeve in the direction of a second end of the splined sleeve. The outer cylindrical shell surface area is formed in a stepped manner. The outer cylindrical shell surface area comprises a first cylindrical section and a second cylindrical section which has a diameter larger than the diameter of the first cylindrical section. Between the sections, a conical area is provided.Type: GrantFiled: March 19, 2019Date of Patent: September 28, 2021Assignee: ROLLS-ROYCE DEUTSCHLAND LTD & CO KGInventors: Christos Kallianteris, Jan Schwarze

Publication number: 20200408152Abstract: A gear box, in particular a planetary gear box of a gas turbine engine, is proposed, having at least one planet carrier which comprises two webs which are spaced apart in an axial direction. By means of the webs, at least one planet gear which is configured to be rotatable relative to the planet carrier is operatively connected to the planet carrier. An axis of rotation of the planet gear, below or in the case of a defined load-dependent deformation of the planet carrier, deviates from a parallel course of an axis of symmetry of the planet carrier. Furthermore, the axis of rotation of the planet gear, in the case of a further defined load-dependent deformation of the planet carrier greater than the defined load-dependent deformation of the planet carrier, runs at least approximately parallel to the axis of symmetry of the planet carrier.Type: ApplicationFiled: June 22, 2020Publication date: December 31, 2020Inventors: Gregor KAPPMEYER, Gideon Daniel VENTER, Jan SCHWARZE, Daniel SIEGHART

Patent number: 10670139Abstract: A planetary gear device for a turbomachine includes a planetary carrier and planetary wheel arranged in an axial direction between two planetary carrier areas connected to a support appliance, with the planetary wheel rotatably mounted on the support appliance. On outer sides facing away from the planetary wheel, the planetary carrier areas include cone surfaces that enclose connection areas with the support appliance, with diameters decreasing with increasing axial distance from the planetary wheel. Cone surfaces of a tensioning appliance radially enclose and are respectively adjusted thereto and act together such that a force that respectively results from an axial tensioning force of the tensioning appliance applied on the cone surfaces of the planetary carrier areas is applied at the connection areas between the support appliance and the planetary carrier areas. The tensioning appliance cone surfaces operatively connect via a coupling element.Type: GrantFiled: August 24, 2018Date of Patent: June 2, 2020Assignee: ROLLS-ROYCE DEUTSCHLAND LTD & CO KGInventors: Gideon Venter, Jan Schwarze

Patent number: 6061843Abstract: In a method for automatically triggering flushing of a urinal with water an electrically actuatable shut-off valve is arranged in the water inlet line for shutting off water flow. A temperature sensor is positioned at a siphon of the urinal. Signals generated by the temperature sensor are sent to an electronic control and computing device. A temperature gradient is determined with the electronic control and computing device based on the signals generated by the temperature sensor. The shut-off valve is opened for flushing the urinal when the temperature gradient exceeds a preset limit.Type: GrantFiled: November 30, 1995Date of Patent: May 16, 2000Assignee: Keramag Keramische Werke AGInventors: Hans Rump, Norbert Pieper, Jorg Hiller, Jan Schwarze
