This　paper　describes　the　nonlinear　finite　element　analysis　model　of　double　circular　helical　bevel　gear　nutation　drive,　the　model　considering　the　changes　of　elastic　contact　deformation,　friction　force　and　the　number　of　meshing　tooth　of　gear,　reflecting　the　actual　driving　situation　of　the　gear　in　nutation　transmission　and　dynamic　loading.　The　dynamic　meshing　of　double　circular　arc　spiral　bevel　gears　at　different　rotate　speeds　is　simulated　by　nonlinear　finite　element　analysis　software,and　vibration　displacement,　dynamic　meshing　stress　and　contact　force　of　nutation　gear　and　output　gear　are　analyzed.　In　order　to　improve　the　stability　of　nutation　drive　and　reduce　the　vibration　and　noise,　the　nonlinear　dynamic　meshing　analysis　of　nutation　drive　cannot　be　ignored.　©　2019,　Springer　Nature　Switzerland　AG.
