Study on Welded Structure Gears : 8th Report, Analysis of Web and Rib Stresses

Abstract

This paper presents a study on the root fillet, web and rib stresses and tooth deflections of thin-rimmed spur gears with different web thicknesses and arrangements by the three-dimensional finite element method (FEM). The effects of web thickness and rib on web and rib stresses of single web gears with ribs were investigated by carrying out web and rib stress analyses by FEM and a static bending test. The effects of web thickness, rib and maldistribution of loads along face width on root stress distributions and tooth deflections were clarifies. Furthermore the effects of web distance and maldistribution of loads along face width on root stress distributions of double web gears were investigated.
