Figure 264 Pitting caused by gear overloading.
Over/oading
The wear patterns generated by excessive gear loading vary, but all share similar com-
ponents. Figure 26-4 illustrates pitting caused by excessive torsional loading. The pits
are created by the implosion of lubricating oil. Other wear patterns, such as spalling and
burning, also can help identify specific forcing functions or root causes of gear failure.
