AGMA New Standard – ANSI/AGMA 2015-2-B15

6The AGMA (American Gear Manufacturers Association) Technical Division has released a new standard for immediate distribution: ANSI/AGMA 2015-2-B15, Gear Tooth Flank Tolerance Classification System – Definitions and Allowable Values of Double Flank Radial Composite Deviations. This standard establishes a classification system for double flank radial composite tolerances (allowable values of deviations) of individual cylindrical involute gears, sector gears, racks, cylindrical worms, worm gears and hypoid or bevel gears. It serves as a concise means of specifying allowable gear geometry deviations and simplifies discussions between the gear manufacturer and purchaser. It specifies the appropriate definitions of double flank radial composite gear tooth geometry deviations, the structure of the tolerance system and the tolerances.
