AGMA 6008-A98 PDF

This standard describes the specification data required to adequately inform the producer of powder metallurgy (P/M) gears about the gear design features desired by the purchaser. It also describes some of the related industry practices which commonly apply unless replaced by written agreement between producer and purchaser.

Types of gears

The general specifications in this standard cover selected types of gears made by the P/M process. Specifications on gear tooth geometry are described in detail for external spur and helical gears and for straight bevel gears. Similar specifications can also be applied to other types of gears, such as internal gears, with the substitution and addition of the required gear feature data.

Types of P/M processes

This standard applies to gears made by the conventional P/M process consisting of compaction followed by sintering and, in some cases, by post sintering treatments. Gearsmade by metal injection molding (MIM) or other P/M processes may require other specifications or practices.
