Byusing CATIA

a parametric model of spur gear and a face gear model are built.After that

they are converted into ADAMS to establish the simulation model of orthogonal face gear transmission system.Through the dynamics simulation

it is received that the data of output speed and meshing force in the process of meshing.The result tended to be consistent with the conclusion of gear meshing theory by analyzing.It reflected the load history of meshing more truthfully

and the input information of load history is provided for an analysis and calculation of the face gearfatigue life more accurately.
