Damage and strength design of gears

Introduction to gear damage, types, and causes!

The strength design of gears, like the design of general machinery, is carried out with the aim of preventing damage, and among various designs, strength design occupies a particularly important position. The strength design for gears is mainly conducted regarding: - Bending strength of the teeth - Surface pressure strength of the teeth - Scoring strength of the tooth surface against seizure. There are many types of gear damage, but they can be broadly classified into two categories: tooth breakage and surface damage. Common examples of tooth breakage include fatigue breakage and overload breakage. Fatigue breakage occurs when a load is repeatedly applied that generates bending stress exceeding the material's fatigue limit at the root of the tooth, leading to cracks that initiate from the root fillet and propagate, causing tooth breakage. Overload breakage occurs when an extremely large overload acts on the tooth, resulting in breakage due to one or a few repetitions of slight loads. As for surface damage...
