Sažetak
To obtain the change tendency of the wheel’s
angular velocity and tangential component of
contact force with time of the pinion under the step
input during spiral bevel gear meshing, the tooth
flank equation of spiral bevel gear was constructed
based on the Non-Uniform Rational B-splines
curve. The three-dimensional model of the pinion
and the wheel were built based on the tooth flank
equation. The calculation equation and relative
parameters set for the contact force of spiral bevel
gear meshing were done based on the Hertz
contact theory. A mating of spiral bevel gears was
taken as an example for dynamics simulation and
the simulation results show that the relative error
rate of the angular velocity between simulation and
theoretical calculation is 0.054%, and that the
relative error rate of tangential component of the
contact force between simulation and theoretical
calculation is 4.82%. These findings provide the
theoretical basis for dynamic characteristics
optimization of the spiral bevel gears.
