Planetary gearbox of the coaxial helicopter
grabcad
The coaxial helicopter employs a planetary gearbox to ensure equal speed distribution between two shafts, which rotate in opposite directions. This compensates for the reaction torque of each screw. The planetary differential system utilizes a four-satellite gear with no locked components. The sun gear has 34 teeth, while the satellite gears have 26 teeth and the crown gear has 86 teeth.
