Study on Minimum Teeth without Undercutting of the Stub Tooth Involute Gears Based on VB

Abstract

Based on the principle of gear generating, theoretical research and VB software simulation about undercut are presented in this paper. The rack cutter is used to infer minimum teeth without undercutting of stub tooth in volute gear, stub tooth helical gear and stub tooth straight bevel gear. And, which are respectively analyzed and calculated. Thus, correct minimum teeth without undercutting are got, theoretical analysis and calculation on the in volute stub tooth gear have been carried out. Then, minimum teeth without undercutting can be obtained, and use VB software to carry on simulation for verifying the validity of the theoretical calculation.
