WebPlanetary gears are common in transmission systems, where they provide high gear ratios in compact geometries. A carrier connected to a drive shaft holds the planet gears. Ports C, R, and S represent the shafts connected to the planet gear carrier, ring gear, and sun gear. WebThe planet-sun gear ratio is defined as g P S = r P r S = N P N S, where: gPS is the planet-sun gear ratio. As r P > r S, g P S > 1. NP is the number of teeth in the planet gear. NS is the angular velocity of the sun gear. In terms of this ratio, the key kinematic constraint is: ω S = g P S ω P − ω C for a left-oriented bevel assembly
