Method & Evidence

AimHow can a novel double-crown tooth surface modification methodology improve the load-bearing capacity and stress distribution of non-orthogonal helical face gears?

MethodComputational analysis and simulation

ProcedureA two-stage tooth modification strategy was developed: first, modifying the tool profile to adjust the tooth profile direction, and second, refining the tool-gear interaction to alter the contact path. Tooth contact analysis (TCA) and loaded tooth contact analysis (LTCA) were performed to evaluate the effects of this modification on contact stress, tooth root bending stress, and misalignment error resistance.
