Some kinds of design features factor into distress and failure. Hertzian strength, or beam strength, refers to the ability of a gear tooth to withstand repeated loadings. It is a measure of the load-carrying ability of a pair of gears. It has to be greater than the maximum dynamic load of the gear. Fatigue occurs when a … See more Pitting is the most common failure mode for gear teeth. It’s due to repeated loading and contact stresses exceeding surface fatigue strength of … See more A type of spalling, case crushing, is associated with heavily loaded case-hardened gears. Case crushing appears as long longitudinal cracks on the tooth surface, which can … See more Spalling describes a large area where the surface material has broken away from the tooth. It can appear as overlapping or interconnected large … See more Wear describes loss of material from the contacting surfaces of a gear.
