Fig.2: Equal and opposite forces around the sun equal no side force on the shaft and bearing at the centre, The same can be shown to apply to the planets, ring gear and planet carrier. Of course, the planets have to be spaced far enough from each other so that they do not interfere. To accomplish this, the total number of teeth in the ring gear and sun gear combined divided by the number of planets has to equal a whole number. The planets will typically be spaced at regular intervals around the sun.

In your basic setup, your ring gear will have teeth equal to the number of the teeth in the sun gear, plus two planets (though there may be advantages to modifying this slightly), simply because a line straight across the center from one end of the ring gear to the other will span the sun gear at the center, and room for a planet on either end. Generally the planets are the same size, at a common center distance from the center of the planetary gear, and held by a planetary carrier.

Planetary gears normally consist of three parts A single sun gear at the center, an internal (ring) gear around the outside, and some number of planets that go in between. Fig.1 Components of a planetary gear Planetary Gears

In this article weвЂ™re going to look at the particulars of planetary gears with an eye towards investigating a particular family of planetary gear setups sometimes known as a вЂdifferential planetaryвЂ™ set. Particularly mesmerizing are planetary gears, where the gears not only spin, but orbit around a central axis as well.

ThereвЂ™s just something about spinning bits of metal (or some other material) meshing together that is mesmerizing to watch, while opening up so many possibilities functionally. I donвЂ™t think there is a mechanical engineer out there who doesnвЂ™t have a soft spot for gears.
