Study on Welded Structure Gears : 7th Report, Analyses of Root Fillet and Rim Stresses

Abstract

In the present paper, the root fillet and rim stresses and the tooth deflections of thin-rimmed spur gears with different rim thicknesses and web arrangements were analysed by the three-dimensional finite element method. The method of changing the rim thickness of a thin-rimmed gear model in the FEM-analysis was examined and on the basis of the obtained results the effects of rim thickness on the root stress distribution were investigated. Furthermore the root and rim stresses of thin-rimmed gears with different web arrangements were computed and measured. The effects of web arrangement on the root fillet and rim stress distributions were clarified to a considerable extent.
