Abstract

Gear to change the blade angle of variable‐pitch air‐screws, while stopped or running, operated manually or by means of another source of power, consisting of a driving wheel, or driving gear, rigidly connected with the source of power and further of a wheel, fixed loosely to the shaft and revolving relatively in regard to it, with a transmission gear (rotating double wheel) or groups of transmission gears in order to turn the blades around their axis, characterized in that each rotating wheel 2, 3 of the transmission or the transmission group is formed as a single wheel 2′ with correspondingly wide toothing whereby one or both central wheels, in gear with that wheel, have a corrected toothing, thus differing only in the number of teeth, while their diameter is equal.
