Simulation Research on Undercutting Properties of Involute Gears Based on VB

Abstract

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.

New Insights Into the Minimum Teeth Number and Modification Coefficient of Standard Involute Gears Without Undercutting

“…During the study of the minimum number of teeth of standard involute gear teeth without undercutting, the concept of 'rack cutter has been mistakenly regarded as rack in the study of the minimum number of teeth without undercutting in many textbooks' is promoted for the first time [32] by the researchers. In the studies of involute spur gear undercutting with different pressure angles based on the VB programme and the neural network method, undercutting of involute gear with different pressure angles, namely, 14.5°, 22.5°, and 25°, are discussed [33][34][35][36][37]. Researchers from all over the world are dedicated to the gear design and manufacturing research and a significant amount of important findings have been acquired.…”
