General Mathematical Model of Internal Meshing Spiral Bevel Gears for Nutation Drive

Applied Mechanics and Materials, 2011
The general mathematical model of internal meshing spiral bevel gears for nutation drive is studied. Based on conventional enveloping theory and transmission principle, the meshing of two spiral bevel gears in nutation drive was substituted by the meshing of an imaginary rotating crown gear engaging with the external and internal bevel gear ...
