Comparison of the Size and Efficiency of a Two-carrier Planetary Gear Train and Kinematically Equivalent Planetary Gear Trains [PDF]
Acta Technica Corviniensis, 2022 A two-carrier planetary gear train (PGT) developed for a specific purpose is discussed in this paper. This PGT is suitable for applications which require negative transmission ratios in the range from -3 up to -143. The mechanical and dimensional characteristics of the planetary gear train for nominal negative transmission ratios of -30 and -40 have ...
