Fig. 22 Schematic of rolling-sliding action inherent in gear teeth. As gear teeth contact, rolling (R) and sliding (S) stresses are formed by the relative movement. Pure rolling occurs only at the pitch line, and on each gear the direction of sliding reverses at the pitch line. Analysis More

Fig. 13 Cross section of worn gear teeth. Approximate width of steel segment shown is 23 mm (0.9 in.). More

Fig. 95 Bending fatigue strength of gear teeth at (a) tooth gap hardening and (b) flank hardening for various steels. Broken lines denote confidence limit according to DIN 3990. Source: Ref 36 More

Fig. 23 Spalling of spiral bevel gear teeth. Original pitting low on the active profile gives initiation to a fast and extensive progression of spalling over the top face and down the back profile. This is often called the cyclone effect. Original magnification at 0.25× More

Fig. 32 Spiral bevel gear teeth showing contact wear. Insert A shows a tooth area exhibiting no wear. Insert B shows abrasive wear clearly cutting away 3.2 mm (⅛ in.) of the surface without damage to underlying material. More

Fig. 4 Pitted gear teeth. Note micropitting at the pitch line, scattered macropits, and one area of gross pitting near the left end. More
