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.

Time-varying Meshing Stiffness Calculation of Spur Gears with Asymmetric Spalling Defects
International Journal of Mechanical and Electrical EngineeringGear systems are subjected to repeated loads during long-term operation, and factors such as insufficient lubricant to increase friction between gears, resulting in elevated temperatures and wear, are highly susceptible to tooth spalling. Tooth spalling is a common form of failure in gear failure.

Calculation and Analysis of Modified Gear Time-varying Meshing Stiffness based on Matlab
Jixie chuandong, 2022 Considering the real involute and transition curve equation of gears，an accurate model of gears is conducted. The deformation of modified gear is deduced and calculated by Weber energy method. The mapping relationships of load angle βj，pressure angle αk，rotation angle tan αk and coordinate XMj of load point are deduced.
