  • the guide tube 9 may take other forms than a tube and the material may vary again here. The important thing is that it is so tight that the fluid does not get inside.
  • connection 11 With the lower gear 5, which is rotatable.
  • connection must be so close that no fluid gets inside and that the lower gear housing 10 is rotatable. Both requirements are achieved by different seals and bearings.
  • the transmission housing 10 is the end facing away from the drive 2 formed end 12 of the main shaft 4, which is connected to the transmission housing 10 via a bearing bracket 13.
  • bevel gears 14 are added, which mark a drive 2 facing trained end of paddle shafts 15. As Fig. 2 can be removed, each has a paddle shaft 15 a bevel gear 14.
  • the bevel gears 14 are, as in particular in Fig. 2 recognizable, via a drive gear 16 which is rotatably connected to the main shaft 4, with each other in operative connection.
  • a WälzEffgetriebe is formed.
  • the bevel gears 14 are driven by the conical drive gear 16 of the main shaft 4. Due to the compound, i. rotationally fixed connection of the bevel gears 14 with their respective associated paddle shaft 15, the paddle shafts 15 are set in rotation.
