An Adaptive Finite Element Analysis for Tooth Deformation
and Load Distribution of Helical Gears Yi Zhang
and Hsiang H. Lin
Abstract
An adaptive model of three dimensional finite element
approaches has been developed to perform static analysis of
helical gears. Several typical contact conditions due to
different tooth engagement positions and face widths are
studied. Tooth deformation and load distribution along the
contact line of separate contact conditions are calculated
and compared. For gears with narrower face width or smaller
helix angle, local contact compliance has a very significant
effect on the total tooth deformation and the load
distribution along the contact line is more uniform. On the
contact line, the magnitude of tooth load is greater at the
points that have higher meshing stiffness and lower
deformation. The present model provides more detailed
information regarding tooth surface deformation when
compared with existing gear literature. It can be used to
design helical gears for minimum transmission error to help
reduce dynamic loading and stress of the gear systems.
