Influence of Hobbing Tool Generating Scallops on Root Fillet Stress Concentrations


This paper will discuss the specific example of parallel-sided splines manufactured with a finish hobbing process, and the effects of generating root fillet stress concentrations. To estimate the value of the stress concentrations, finite element analysis was performed on the components for two unique hobbing tool designs. The FEA results were then correlated to actual components with known field service lives. ISBN: 1-55589-021-6 Pages: 10 Authors: Benjamin S. Sheen, Matthew Glass
