This article considers the Wolfrom planetary gear train, its most used variants and areas of application. It is emphasized that the train is a compound one, and not a simple one (single-carrier). It is demonstrated how a kinematic and power (efficiency) analysis of the gear train under consideration may be performed using the lever analogy and the torque method based on it. Equations for efficiency determination useful in the optimization procedures of Wolfrom planetary gear train have been developed, and propositions for its application have been given.
