Compared with the traditional gearboxes, planetary gearbox has a
different transmission method. The traditional ones are merely
driven by big gears and small gears. The interface between the two
gears endures the load all by itself. Therefore, the interface is
more apt to wear out. This is even worse in the high speed
gearboxes that contain more gears. The interfaces between the gears
have to bear multiplied loads. The inaccuracy multiplies and the
transmission efficiency is therefore greatly reduced.
The planetary gearbox, however, has six interfaces among the sun
gear, planetary gears and the annulus. The loads are equally
distributed to these interfaces. Therefore, the friction and load
in the interfaces are greatly reduced. This float type transmission
also has small gaps between two gears. This relatively reduces the
volume of the gearbox and increases the efficiency to 97%.
