Patent abstract
An epicyclic gear transmission primarily intended for use in rotary wing aircraft that utilizes a plurality of planet gears axially spaced on a planet gear shaft. The planet gear shaft is tilted or inclined at an axis with respect to the center axis of the input shaft or sun gear. In addition, the planet gears may include a shallow angle face gear. The tilted axis planet gears obtain a reduction in size of the transmission and correspondingly reduce the overall weight thereof.
