ABSTRACT:
A speed reducing gear box of the type including, for each reducing stage, a plurality of planetary gears revolving about a central sun gear and inside an internal gear, the improvement of axially loading the planetary gears to provide sufficient friction to retard ballotting of said gears but not to substantially reduce power transmission of said gear box and to allow use of a tighter planetary gear mesh to decrease angular transmission errors.
