Gear Failure Analysis Involving Grinding Burn
January 1, 2009
When gears are case-hardened, it is known that some growth and redistribution of stresses that result in geometric distortion will occur. Aerospace gears require post case-hardening grinding of the gear teeth to achieve necessary accuracy. Tempering of the case-hardened surface, commonly known as grinding burn, occurs in the manufacturing
process when control of the heat generation at the surface is lost.
