Load Tooth Contact Analysis for Double-Crowned Face Gear

Abstract

In order to further reduce sensitivity to misalignments not only double crowned pinion but also profile and longitudinal geometry modified face gear have been studied. The profile geometry modification were realized by application of rack cutters, and applied parabolic motion of the center of grinding disk for the pinion and face gear longitudinal crowning. Tooth contact analysis (TAC) and Load Tooth contact analysis (LTCA) have been performed to simulate the meshing and contact of double-crowned face gear driver. The further avoidance of edge contact in presence of big magnitude misalignment was illustrated with numerical examples.
