The dynamic model of the rotating roulette was established and the dynamic frequency solution finite element method based on the stiffness matrix in the centrifugal stiffness matrix correction mode was proposed. The numerical solution of the spiral frequency of the spiral bevel gear was realized. The numerical calculation is basically consistent with the measured value and the conclusion is drawn from the calculation that the rotation effect has a great influence on the low-order mode and the pitch mode. The algorithm has universality to the moving frequency calculation of rotating roulette
