WebAug 1, 2007 · Figure 6--Maximum and intermediate principal stress distribution at the tooth root fillet in the sides of the gear: Full-body gear with b = 20 mm. The highest value of the maximum principal stress in a cross-section--herein named bending stress--may be used to characterize the stress levels along the face width. WebAug 3, 2024 · While doing design analysis of spur gear, we consider the teeth of gear as a cantilever beam. As we see that two forces acting on the tooth, the radial component results in the compressive stress and tangential components result in the bending stress in the gear tooth, as the magnitude of radial force is less than that of the tangential component.

Webprimary property of the gear tooth that provides resistance to pitting. In other words, pitting is a surface fatigue failure due to many repetitions of high contact stress, which occurs on gear tooth surfaces when a pair of teeth is transmitting power. Gear teeth failure due to contact. Fatigue is a common phenomenon observed. WebIf the load is bidirectional, and both sides of the tooth are equally loaded, the value of allowable bending stress, σFlim, should be taken as 2/3 of the given value in the table.
