Abstract
A reversed Lewis root bending stress capacity model for bevel gears is presented. The model is developed from first principle based on the Tredgold’s approximation of a bevel gear. The approximation conceptually transforms a bevel gear into a spur gear. The load distribution of the bevel gear facewidth is assumed to be triangular so that the stress at the gear is constant over the facewidth. Six design cases of root bending stress computations from different references are done using the new and AGMA models. The stress estimates from the new and AGMA models were compared. The stress deviations associated with the pinions in the gearsets for the design problem examples vary between -14 to -4%, approximately. Based on the values of the deviations for the pinion stresses, the new root bending stress model verification may be said to be favorable when compared with AGMA stress values. However, the root bending stress predictions are relatively less conservative in values.
