90PX planetary gear reducer

90PX planetary gear reducer: The main transmission structure is planetary gear, sun gear, and outer ring gear. Planetary gear reduction is actually the principle of gear reduction. It has a fixed axis gear called the heart gear or sun gear, on the side of the sun gear. Gears with axis changes, that is, gears that both rotate and revolve are called planetary gears. Planetary gears have supporting components called planetary carriers. The power is transmitted to the shaft through the planetary carrier, and then to other gears. They consist of a set of several gears. The gears form a gear train. There is only one prime mover. This epicyclic gear train is called a planetary gear train.
