Abstract: The dynamic transmission accuracy for the 2K-V- type drive is researched in comprehensive consideration of the nonlinear factors (such as manufacturing errors, assembly errors, clearances, meshing stiffness of gears and bearings, etc.). The nonlinear dynamic model is set up and is solved by using Newmark method. So it lays a good theoretical foundation for the research of the dynamic transmission accuracy of 2K-V-type drive and is also beneficial to the research of dynamic transmission accuracy of other similar gear drives.

Key words: 2K-V-type drive Dynamic transmission accuracy Nonlinear dynamic model Newmark method
