Due to its distinctive transm ission principle and structural character, the study on TRGR attracts wide attention. This arti cle focuses on the current TRGR vibration and noise problems caused by transmission mechanism which leads to non-dynamic balance. So it puts forth and fu rther makes theoretical and experimental research on three-phrase five-r ing gear reducer as a solution. Firstly, the article studies the principle of TRGR transmission and establishes the few teeth inside engage d ary gear me sh equation. By analyzing the stress on the drive gear, it calculates an d analyzes the stress on t
