Gear Contact Temperature and Scuffing Risk Analysis

Synonyms

Galling; Seizure; Severe adhesion

Definition

Scuffing is localized damage caused by solid-phase welding between surfaces in relative motion. It is accompanied by transfer of metal from one surface to another due to welding and subsequent tearing. ANSI/AGMA 1010-E95 (1995) describes the characteristics of the failure mode. AGMA 925-A03 (2003) gives information on effects of lubrication on gear surface distress. Figure 1 shows scuffing on a spur pinion.
