摘要： 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.

摘要： 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.
