Tooth-bending fatigue is the most common mode of failure in gearing and results from cracking under repeated stresses below the ultimate tensile strength of the gear [4]. Notches, grooves, surface discontinuities, and material imperfections will decrease the stress that can be withstood for a fixed number of cycles.

Webtooth profile, highest location of full load on the tooth profile and fillet geometry of the gear tooth influenced the bending strength of the gear tooth. For the gears with thin rim, rim thickness is another significant factor due to rim deflections. The gears considered by most of the authors are either small or they having less number of teeth. WebJan 8, 2024 · At present, most straight bevel gears use a root fillet transition surface with a radius of 0.3 modulus. This tends to cause excessive root bending stress and reduces the service life of bevel gears. In order to solve this problem, a root fillet transition surface controlled by a set of third-order Bezier curves is designed based on spherical involute …

WebMar 6, 2024 · Tooth bending failure, one of the gear’s most dangerous failure modes, is caused by alternating bending stress at the tooth root. The fatigue process is divided into crack initiation and crack propagation periods. In this paper, single tooth bending fatigue tests are conducted under a stress ratio of 0.05. Crack initiation life is predicted by the …
