Abstract Planetary gearboxes nowadays serve as the heart of complicated structures such helicopters, presenting a number advantages. They have compact size and low weight, achieving high power density efficiency. Moreover gearing can be very accurate with virtually no backlash modular, most stages stacked. Furthermore, last years planetary been introduced in area air breathing engines, helping ...
