Abstract
In this chapter, a general survey is first done on the tooth bending strength of bevel gears in the broadest meaning, including straight, helical (or skew), Zerol, spiral bevel and hypoid gears and the main factors affecting the tooth root stress state are defined. Attention is paid to the fatigue breakage at the tooth root of these gears and safety factor to be used for their design. The theoretical bases of calculation of tooth bending strength, already discussed in previous chapters, are then recalled, particular those concerning the Lewis constant strength parabola, 30° tangent and cantilever rectangular plate with constant thickness subject to bending load, with which the gear tooth is simulated. The methods of adaption of these theoretical bases to bevel gears are then described. A large part of the chapter is reserved for the procedures to calculate the tooth bending strength of these types of gears in accordance with the ISO standards, highlighting when deemed necessary as the relationships used by the same ISO are founded on the theoretical bases previously recalled.
