The transmission efficiency formula of 2K-H planetary gears transmission based on the directed digraph and screw theories are deduced considering the influence of the gearbox shell and friction torques of the gear pairs, the formula are associated with the pitch radii of the of the sun gear and ring gear and the friction coefficient magnitude of the gear pairs. The transmission efficiency of 2K-H planetary gears transmission increases with the number of teeth of the sun gear and the ring gear increasing, but it decreases with the friction coefficient magnitude increasing, which the influence degrees are not the same.
