Abstract: A very useful new method of
tooth contact finite element analysis (TCFEA) for spiral bevel
and hypoid gears is presented, combines 3-d finite element
contact stress analysis with LTCA (Loaded Tooth Contact
Analysis). The TCFEA uses mixed finite element method to analyze
the 3-d contact stress. The related formulas are derived and an
efficient analyzing method as several pairs of teeth in contact
occurs is presented, which greatly reduce the computational
amount. It is of great significance that the tooth stress,
geometry, contact condition and load are all considered in the
same model. Finally the related experimental results are used to
verify the solution of TCFEA.
