AGMA 2015-1-A01 PDF

This part of ANSI/AGMA 2015 establishes an accuracy grade system relevant to tangential measurements on flanks of individual cylindrical involute gears.

It specifies definitions for gear tooth accuracy terms, the structure of the gear accuracy grade system, and allowable values.

It is strongly recommended that any user of this part of ANSI/AGMA 2015 be very familiar with the methods and procedures outlined in AGMA 915--1--A02. Use of techniques other than those of AGMA 915--1--A02 combined with the limits described in this part of ANSI/AGMA 2015 may not be suitable.

This standard provides the gear manufacturer and the gear buyer with a mutually advantageous reference for uniform tolerances. Ten accuracy grades are defined in this standard, numbered A2 through A11, in order of decreasing precision.
