文摘
- •
A 10 DOF lateral-torsional--rocking coupled nonlinear dynamic model of a single gear system is proposed.
- •
The influences of geometric eccentricity, gyroscopic moment, teeth to the partial load torque and backlash on dynamic model are analyzed.
- •
The stiffness of modification gear is studied by mesh model.
- •
The optimal modification amount which minimizes the dynamic load is found, and can effectively reduce the mesh stiffness mutation and the dynamic load of gear.
- •
The influence of optimal modification on contact rate of gears is negligible.
