Title

Strength Calculation for Forged Straight Bevel Gear Teeth Having a Linking Web

Abstract

When bevel gears are forged, a thin web results on the back of the teeth. This web, which results from the clearance between the dies, gives an additional strength not accounted for when the Lewis design criteria is used. To account for this extra strength a plate model is developed. The solution for this plate model can be obtained by assuming a polynomial deflection function. Using the Galerkin variational method the constants in this assumed deflection function can be calculated. The plate model is compared with a finite element model, using a general purpose program and also with experimental strain measurements. This proposed plate solution indicates an increase in strength of more than 25% in excess of that suggested by the cantilever beam model of Lewis when compared with the finite element results.
