Research into the Properties of Selected Single Speed Two-Carrier Planetary Gear Trains

A two-carrier planetary gear train (PGT) configuration, named S13WN, was developed for a specific application with a negative transmission ratio in the interval between -20 and -21. 72 valid combinations of component PGTs ideal torque ratios have been developed for this configuration, from which kinematically feasible combinations providing minimal dimensions and maximum efficiency within the required interval have been selected. The minimal dimensions of the PGT were achieved with a cylindrical case shape, i.e., with the ratio of the ring gears reference diameters close to unity. Nine other PGT configurations have been synthesized for the same transmission ratio, and their design parameters optimized. The two solutions that offer the most improvements over S13WN have been developed into design concepts.
