Definitions

  • a threaded hole 9 in the center for a self-locking thread ie a thread with a small pitch.
  • An associated thread end 10 is guided in the threaded bore 9 at the end of an adjusting shaft 11.
  • the adjusting shaft 11 extends through the hollow propeller shaft 5, it is mounted axially immovably at 12 in the area of the bevel gear 4, ie outside the propeller hub 6.
  • the adjusting shaft 11 carries a threaded end 13 of a non-self-locking thread, that is, a thread with a large pitch.
  • This threaded end 13 is guided in an associated threaded bore 14 which is arranged at the end of a piston rod 15.
