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 ...

Biological Reviews, EarlyView.ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis
