Effect of Mounting Displacements on Bevel and Hypoid Gear Tooth Strength

An accurate appraisal of gear tooth stresses is dependent upon knowledge of the deflection characteristics of the gear mounting as well as the details of gear geometry. For optimum load-carrying capacity it is most desirable to achieve as nearly uniform load and stress distribution as possible; and thus gear mountings should be designed to this end. The equations for effective face width and load distribution factor can be introduced into the basic gear tooth strength formulas to give more accurate stress values; in this paper bevel and hypoid gears are discussed in this context.
