1.1 This information sheet covers all aerospace spur
and helical power gears lubricated with MIL-L-7808
and MIL-0-6081, Grade 1005 Oils.
1.2 The purpose of this information sheet is to
present an improved flash temperature index formula
and a recommended operating index range which will 1 serve as a guide to designers for determining the
I scoring resistance of spur and helical gear sets intended
for use in aerospace applications.
