Winch Bin » Winch Gearing Types Explained

The gear in the center of the larger gear engages two or three smaller gears in the same large gear. Planetary gears turn on a movable center and the sun gears turn on a fixed center. Planetary gears are also used to produce different gear ratios depending on the which gear is used as input, which one as output and which one is held stationary.
