Simulation Research on Undercutting Properties of Involute Gears Based on VB

Establishing the corresponding relationship between radius at tooth tip and tooth root fillet by the curvature of conjugate flank based on the generating method to manufacture for gears. According to the Visual Basic, a 2-D mathematical model of relationship between undercutting phenomena and modulus, teeth and modification coefficient of involute gear was built, and then simulated undercutting influence level caused by modulus, teeth and modification coefficient. The generating method dynamic processes, generating profile and the root drawing obtained by the simulation will directly reflect the influences that modulus, teeth and modification coefficient with gears meshing processions, and provided a reliable basis for design gear transmission and machining involute gears.
