  • Patent number: 10823279
    Abstract: A spur gear transmission has at least two toothed spur gears with toothings that are in meshing engagement with one another and which are each rotatable about an axis of rotation. An enveloping wall at least partially encloses the two spur gears in a circumferential direction and in the direction of the axis of rotation. The enveloping wall has an inner contour adapted to the outer diameters of the spur gears such that, between the enveloping wall and the spur gears, there are formed two ring-shaped gaps which transition into one another, wherein in each case one ring-shaped gap is arranged concentrically with in each case one axis of rotation. A lubricating device conducts a lubricant flow into the toothings of the spur gears. A cooling device is additionally provided, which conducts a coolant flow through one or more cooling ducts within and/or along the outside of the enveloping wall.

  • Patent number: 10816081
    Abstract: A spur gear transmission with at least two intermeshing spur gears the teeth of which are in meshing engagement with one another, and each of which are rotatable via an axis of rotation. The spur gear transmission has an enveloping wall which surrounds the two spur gears in circumferential direction and in the direction of the axes of rotation. The enveloping wall has an inner contour which is adapted to the outer diameter of the spur gears in such a manner that two annular gaps which merge into each other are formed between the enveloping wall and the spur gears. One annular gap respectively is arranged at least substantially concentrically with respect to a respective axis of rotation. The enveloping wall is formed by a two-part housing which is closed along a parting line and which has an upper part and a lower part.

  • Patent number: 10760671
    Abstract: A spur gear transmission has at least two meshing, toothed spur gears. A covering wall surrounds the spur gears circumferentially and in the direction of their rotational axes. The covering wall has an inner contour adapted to the outer diameters of the spur gears. Two annular gaps which transition into each other are formed between the covering wall and the spur gears. The annular gap is substantially concentric to a rotational axis. The covering wall surrounds the two spur gears circumferentially only over a part of the circumference, with a part of the outer circumference of the two spur gears or one of the two spur gears protruding outwards out of the covering wall. The part of the two spur gears or of the one spur gear that protrudes out of the covering wall is positioned on the lower face of the spur gears.

  • Patent number: 8713926
    Abstract: A hydrodynamic machine has two blade wheels disposed opposite each other and together forming a toroidal working space. The space can be filled with a working medium to transmit torque hydrodynamically, by circulating the working medium in the space, from the first to the second blade wheel. The first blade wheel rotates about an axis of rotation. The second blade wheel rotates about the same axis of rotation in the same rotation direction as the first blade wheel or opposite thereto, or is held stationary. The blades of each blade wheel extend in an arc from a radially inner blade end on a radially inner wall of the working space to a radially outer blade end on a radially outer wall of the working space, and in plan view in the direction of the rotation axis the arc is in the shape of a circular arc on each blade wheel.
