General Plate Formula for Bevel Gears with Back Shoulder
Strength of bevel gears can be increased substantially if a web support is provided the back of their teeth. This web can be obtained by either cutting gears through a special gear manufacturing operation, or through the technique of gear forging. In this analysis, the strength due to this back web support is investigated. The new gear tooth configuration, which resembles a plate supported at two adjacent edges is analyzed. The variational energy approach and a finite element modeling technique were also used to analyze six bevel gears. The resulting design equation describes the characteristics of deflection of this new bevel gear tooth more closely than the well-known Lewis design equation.
