摘要： A spur gear transmission has at least two toothed spur gears, the toothings of which are in meshing engagement with one another and which are each rotatable about an axis of rotation. An enveloping wall encloses the two spur gears in a circumferential direction and in the direction of the axes of rotation. The enveloping wall has an inner contour which is adapted to the outer diameters of the spur gears such that ring-shaped gaps that merge into one another are formed between the enveloping wall and the spur gears. Each ring-shaped gap is arranged at least substantially concentrically with respect to a respective axis of rotation. The enveloping wall is formed by a multi-part housing which is closed along a parting joint. The parting joint extends partially or entirely substantially within a plane in which one of the two axes of rotation or both axes of rotation run.
