Common modes of gear failure
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 . Notches, grooves, surface discontinuities, and material imperfections will decrease the stress that can be withstood for a fixed number of cycles. In a … See more Tooth-bending impact is often the result of a shock-loading condition, when a gear tooth will yield due to a bending stress, which exceeds the yield strength of the material. To address this issue, the gear material should have … See more Abrasion occurs when material is removed or displaced due to the presence of hard particles. Examples of hard particles that cause abrasion … See more Failure analysis can be used to identify a root cause for a gear failure, and material properties and characteristics can contribute to these … See more Macropitting due to Hertzian fatigue contact stress, in which cracks initiate at the surface or subsurface of the gear tooth, is another common failure mode in gears . The … See more WebGears can fail in many different ways, and except for an increase in noise level and vibration, there is often no indication of difficulty until total failure occurs. This article reviews the major types of gears and the basic principles of gear-tooth contact.
