  • Patent number: 11905925
    Abstract: A flange arrangement includes a power shaft, a flanged hub connected detachably to the power shaft, and a stop member configured to detachably hold the flanged hub on the power shaft and to exert a disassembly force on the flanged hub so as to be able to rotate about a rotation axis of the power shaft.
    Type: Grant

  • Patent number: 10677331
    Abstract: 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.

  • Patent number: 10550930
    Abstract: A planet carrier arrangement includes a bearing assembly having first and second roller bearings and a traction element having a first end supported by the bearing assembly such as to enable the traction element to oscillate. A planet carrier is mounted in a suspended manner to the traction element, wherein one of the roller bearings of the bearing assembly is configured to absorb an axial force seeking to lift the planet carrier.

  • Patent number: 8544780
    Abstract: An output-side subassembly of a mill drive system is provided. The subassembly includes an output flange, connectable to a grinding dish, for absorbing forces occurring in a grinding process. Moreover, an annular basic element which is mountable on a foundation or carrier element is provided. For supporting the output flange, a plurality of axial plain bearing segments are arranged essentially equidistantly with respect to one another on the annular basic element. In this case, lubricating gaps are formed in each case between the output flange and the axial plain bearing segments.
