Gear Noise Cause of a Different Stripe

摘要

Expert response provided by Andy Milburn, Robert Errichello and Rainer Eckert. The questioner is correct that there is not much published information regarding electrical discharge damage on gear teeth. We assume that they have already looked at (Ref.1), since that is the only paper, we could find that uses the term "Tiger Stripes" for this failure mode (See Figure 1). The good news is that the reason there are not many papers on the subject is likely because it is not a common failure mode for gears. It is however very similar to "fluting" damage caused by electrical erosion on bearings and is much more common in bearings. Reference 1 does not directly address the questions above, so we will attempt to address them here.
