Definitions

  • a second gear 44 is connected in a rotationally fixed manner to the adjusting shaft 2, the bearing on the machine shaft 2 taking place via a needle bearing 42.
  • the second gear 44 meshes with at least one second planet gear 46.
  • the two planet gears 36, 46 are non-rotatably coupled and rotatable about the axis 47.
  • a pin 48 is used to couple the two planet gears 36, 46, each of which engages in a blind bore 50, 52 of the aforementioned planet gears.
  • Three pairs of planet gears 36, 46 are preferably distributed uniformly over the circumference in the manner according to the invention.
