Levai's Epicyclic Planetaries "G" Type

grabcad

Z. Lévai identified 12 distinct types of basic epicyclic trains, labeled "A" to "L". Among these is type "G", known for its simplicity due to planet gears engaging only with the sun and ring (in this case, two suns). The "Scheme" illustrates the equations, while the "Index" displays all 12 mechanisms. Notably, the Simplified Equation remains constant across all 12 designs. These include Levai's Epicyclic Planetaries "A", "B", "C", "D", "E", "F", "G" (the featured type), "H", "I", "J", and "L".
