    • The invention relates to a spur gear transmission with at least two toothed spur gears (1, 2), the toothings of which mesh with each other and each of which can be rotated about a rotational axis (3, 4), comprising: - an enveloping wall (5) which surrounds the two spur gears in the circumferential direction and in the direction of the rotational axes; wherein - the enveloping wall has an inner contour which is adapted to the outer diameters of the spur gears such that two annular gaps (6, 7) which transition into each other are produced between the enveloping wall and the spur gears, each annular gap being arranged at least substantially concentrically to a rotational axis; - the enveloping wall surrounds the two spur gears in the circumferential direction only over a part of the circumference of the spur gears such that a part of the outer circumference of the two spur gears or at least one of the two spur gears protrudes outwards out of the enveloping wall. The spur gear transmission according to the invention is characterized in that the part of the two spur gears or of the one spur gear, said part protruding out of the enveloping wall, is positioned on the lower face of the spur gears.
    • 本发明涉及一种具有至少两个带齿正齿轮(1,2)的正齿轮传动装置,其齿轮彼此啮合,并且每个可绕旋转轴线(3,4)旋转,包括: - 一个 包围壁(5),其围绕所述两个正齿轮沿圆周方向和所述旋转轴线的方向; 其中 - 所述包封壁具有适于正齿轮的外径的内部轮廓,使得在包封壁和正齿轮之间产生彼此转变的两个环形间隙(6,7),每个环形间隙 至少基本上同轴地布置成旋转轴线; - 包围壁在圆周方向上仅围绕正交齿轮的圆周的一部分围绕两个正齿轮,使得两个正齿轮的外周的一部分或两个正齿轮中的至少一个向外突出 包围墙。 根据本发明的正齿轮传动装置的特征在于,两个正齿轮的一部分或一个正齿轮的所述部分从包封壁伸出,位于正齿轮的下表面上。
