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 ...

Recirculation of Parallel-Connected Planetary Gear Trains

Chinese Journal of Mechanical Engineering, 2022
AbstractRecirculation is expected to be identified for its possibility to dramatically decrease the efficiency of planetary gear trains (PGTs). However, it exhibits an unexplained connection with the structure, making it challenging to identify without tedious computation through tooth and speed ratios, thus complicating the design process.

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

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
