Patent number: 10677331Abstract: A vertical mill gearbox includes a drive shaft mounted in a casing for rotation about a rotation axis, and an intermediate shaft configured as a hollow shaft and mounted in the casing for rotation about a vertical second rotation axis. The intermediate shaft has a bevel gear meshing with a bevel-gear pinion of the drive shaft. A torsion shaft is received in fixed rotative engagement with the intermediate shaft and sized to extend beyond the intermediate shaft to define a projecting section to which a sun gear rotatably driven via the intermediate shaft is fixed. A planet carrier is mounted in the casing for rotation about the second rotation axis and rotatably supports an internal gear having an internal tooth system. Mounted to the planet carrier is a rotatable planet gear which meshes with the sun gear and with the internal tooth system of the internal gear.Type: GrantFiled: June 13, 2018Date of Patent: June 9, 2020Assignee: FLENDER GMBHInventors: Simon Becka, Steffen Brun, Matthias Friedrich, Guido Josten, Robert Prusak, Eugen Schlegel, Dirk Schroer, Michael Tegelkamp, Franz Schmeink

Patent number: 10041566Abstract: A gearing arrangement for a vertical mill includes a central shaft mounted for rotation about a vertical rotation axis, a spur gear arranged in fixed rotative engagement on the central shaft, and an output flange rotatably coupled to the central shaft. At least one gear unit having gear pairs is arranged vertically below the output flange, with a pinion gear arranged on an output side of the gear unit for engagement into the spur gear on the central shaft. The gear unit is arranged on a traversing mechanism in such a way that the pinion gear on the output side is movable in relation to the spur gear to engage in and disengage from the spur gear, as the gear unit is moved by the traversing mechanism.Type: GrantFiled: February 9, 2016Date of Patent: August 7, 2018Assignee: Siemens AktiengesellschaftInventors: Steffen Brun, Ali Kemal Kücükyavuz, Franz Schmeink

Patent number: 9956870Abstract: A drive axle assembly for a heavy goods vehicle includes a hollow hub, a wheel body rotatably mounted to the hollow hub, and a planetary gear including first and second planetary gear stages, each having a sun gear, a ring gear and a planet carrier with planetary wheels mounted rotatably in the planetary carrier and meshing with the sun gear and the ring gear. A drive shaft is axially guided through the hollow hub and the sun gear of the second planetary gear stage, with the sun gear of the first planetary gear stage being non-rotatably mounted on a vehicle-distal outer end of the drive shaft. Non-rotatably connected by a screw and pin connection to the hollow hub is an annular disk which has an axial opening and a plurality of boreholes in radially surrounding relationship to the axial opening.Type: GrantFiled: April 22, 2015Date of Patent: May 1, 2018Assignee: FLENDER GMBHInventors: Christoph Messink, Todd R Morman, Lucas Paus, Franz Schmeink, Matthias Weiss

Patent number: 7185559Abstract: A gearbox mechanism is provided for a twin screw extruder having two screw shafts disposed at an angle to one another. The gear mechanism has a multi-stage reduction gearbox, and a distribution gearbox having two output lines connectable to the screw shafts. A first output line comprises a through output shaft. An angularly movable coupling, which is fixed against rotation, is disposed in a second output line placed at the angle of the screw shafts, relative to the first output line, via the coupling. A drive gear of the reduction gearbox is disposed between, and is in engagement with, a gear on the output shaft and a gear on a partial shaft of the second output line. A reduction gearbox and distribution gearbox are disposed, without spatial separation, in a common interior space of a multi-part gearbox housing.Type: GrantFiled: March 1, 2005Date of Patent: March 6, 2007Assignee: A.
