pair of meshing gears 10, 12 producing a cyclicly varying output speed from a constant input speed have each symmetrical half of each gear constructed with the pitchline formed of pairs of successive curves of which the curves of each pair (two pairs as shown) have different polar equations....
In Fig. 6.9, gear 1 is the driver and gear 2 is the driven gear. The pitch line velocity, V, is equal to (6.10) where the pitch diameter d is expressed in inches or mm, and n is the angular speed in rpm. The transmitted power and torque are calculated with (6.11) where is ...
An embodiment includes a system for controlling blade pitch in a rotorcraft having an engine; a drive shaft with a first end and a second end and connected at the first end to the engine; a rotor with two or more blades connected to the second end of the drive shaft; and one or more...
