Meshing of a Spiral Bevel Gear Set With 3-D Finite Element Analysis
The article "Meshing of a Spiral Bevel Gear Set With 3-D Finite Element Analysis" appeared in the March/April 1997 issue of Gear Technology.
Recent advances in spiral bevel gear geometry and finite element technology make it practical to conduct a structural analysis and analytically roll the gear set through mesh. With the advent of user-specific programming linked to 3-D solid modelers and mesh generators, model generation has become greatly automated. Contact algorithms available in general purpose finite element codes eliminate the need for the use and alignment of gap elements. Once the gear set it placed in mesh, user subroutines attached to the FE code easily roll it through mesh. The method is described in detail. Preliminary result for a gear set segment showing the progression of the contact line load is given as the gears roll through mesh.
