The dynamics model for parallel shaft split torque transmission system is built

by using of the equivalent meshing error principle

the motion differential equation of split torque transmission system is deduced

the influence of the dynamic load characteristic and the components manufacturing and installation errors on transmission system load non-uniform coefficient is analyzed.The calculation results show that

the load sharing property of parallel shaft split torque transmission system is improved very obvious

and the load sharing property is influenced by all kinds of the error in the system.
