| Summary: | <p>This paper describes a dynamic mathematical model of a new type
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. Subsequently, the model is analyzed using the ANSYS/LS-DYNA
software, and the dynamic contact characteristics of the nutation gear are
calculated. The simulation results revealed that the nutation transmission
of the double circular-arc spiral bevel gear is reliable. Moreover, the
mathematical verification showed that the simulation is feasible and accurate. The research has important significance for improving the tooth
load capacity and transmission stability of nutation drives.</p> |
