Fig. 5-2. Top corner of a spur gear tooth, 10×. A “bull’s-eye” fatigue fracture centering around a nonmetallic inclusion at the case/core interface. Only one tooth spalled. An isolated, random case. More
Image
Published: 01 June 1985
Fig. 5-27. Internal spur gear induction hardened by scanning one tooth space at a time. The inductor was misaligned, allowing for a nonhardened addendum on one tooth profile. This soft area was easily worn. More

Fig. 5-41. Spur gear, 0.9×. High continual overloads broke down the lubricant barrier, causing deep adhesive wear. More
Image
Published: 01 June 1985
Fig. 6-5. Spur gear, 0.9×. Only two teeth pitted, one low on profile and the adjacent tooth high on profile. Mating gear had two teeth as mirror image. This could only occur with the gears in a static position under a reverberating type of load. More
