Vibration characteristics of single-stage planetary gear transmissions [PDF]

Ingeniare. Revista chilena de ingeniería, 2014
Condition monitoring based on vibration measurement and analysis of planetary gear transmissions has not provided the same good results observed in conventional fixed-shaft gear transmissions. One of the causes being the improper interpretation of the vibration spectrum. The structure of the lines present in the spectrum of the vibrations measured on a

Dynamics of a split torque helicopter transmission [PDF]

, 1992
A high reduction ratio split torque gear train has been proposed as an alternative to a planetary configuration for the final stage of a helicopter transmission. A split torque design allows a high ratio of power-to-weight for the transmission.
