Short summary
This paper describes a dynamic mathematical model of a new type of two-stage nutation drive system with double circular-arc bevel gears. The dynamic displacement-vibration coupling model takes into account the gyro torque and side clearance of the nutating gear. A numerical analysis geometric model of the nutation drive system is developed. The geometric model considers the time-varying and contact deformation of nutation gear meshing.
