Load sharing and contact of hourglass worm gearing

摘要

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 both paris 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 with the load is investigated by comparision of its contact patterns under different loads.
