Recirculation of Parallel-Connected Planetary Gear Trains
Chinese Journal of Mechanical Engineering, 2022 Recirculation 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 ...
