ABSTRACT
This chapter provides examples of the various arrangements of AI-planetary gear trains which have application in different technical areas. The examples are accompanied by comments aiming at facilitating the designer and suggesting successful and time-tested technical solutions. Central elements, such as carrier and sun gear, bearings along with their clearance can help to some extent the equalizing of load distribution between planets, since they create radial mobility necessary for the equalizing movements. There is a great variety of planetary gear trains that are specially designed for a specific application in different areas of industry. Speed ratios of the gear train individual stages depend on the diameters of drums and pulley system ratios of both ropes. Provided that both drums have the same diameters and both pulley systems have the same ratio, to move both ropes at the same velocity, drum angular velocities must be equal.
