Structural and kinematic analysis of planetary gearings

Abstract

By bounding two or more gearings, using a role bear-axle element, we can obtain simple transmissions with caged wheels. A transmission with gear wheels generally has, an axle of fixed rotation, called main axle. The gear wheels whose rotation axles are different from the main axle and that are also mobile are called secondary wheels. The basic kinematical movements of planetary gearings can be determined if we know the movements of M external shafts (M = the mobility of planetary gearing).
