gear. The reducer consists of a ring
gear around three planetary gears and a floating sun
gear. Unlike the other planetary gears, which are fixed in place, the sun
gear has a toothed central spline loosely fitted onto the shaft spline creating a floating sun
gear. A major advantage to the floating sun
gear is the lower decibel level - less noise. When the sun
gear is clamped to the
motor shaft it's fixed solidly, leading to 'rattle' if tolerances vary at all. Thus, it is easy to tell...
