Beveloid gears in planetary gear trains for increased power density and reduced backlash

, 2017
By using beveloid gears in planetary gear trains it is possible to achieve very equal load sharing between the planet gears also for gear trains with more than 3 planet gears, thus making it possible to increase torque density and reduce weight.
