Abstract: Based on solid modeling, the geometry and the FE model of the
hourglass worm gearing are established. By the hybrid method of
FEM and penalty function, the load sharing among tooth pairs and
the stress of contact teeth are calculated, the contact zones
and the distribution of the contact pressure are investigated.
The variation of the contact states with the load is
investigated by comparision of its contact patterns under
different loads.
Key words: Hourglass
worm gearing Load sharing Stress Contact pressure
