18、AL STANDARD iv AGMA 2005 - All rights reserved Foreword The foreword, footnotes and annexes, if any, in this document are provided for informational purposes only and are not to be construed as a part of ANSI/AGMA 1012-G05, Gear Nomenclature, Definitions of Terms with Symbols. In 1926 the AGMA adopt
19、ed a recommended practice for gearing nomenclature, terms and definitions. It included some symbols and abbreviations. A complete revision of terms and definitions by the AGMA Nomenclature Committee was issuedasAGMA112.02inOctober,1948. ThislaterbecameAGMA112.03,andAmerican Standard B6.10-1954, with
20、 ASME as a co-sponsor. A separate project dealing with Letter Symbols for Gear Engineering appeared in 1943 as AGMA 111.01, later becoming AGMA 111.03 and American Standard B6.5-1954. AbbreviationsforGearingwasanotherseparateprojectreleasedasAGMA116.01in1955. Most of these abbreviations were already
21、 listed in American Standard Z32.13-1950 Abbreviations for Use on Drawings, and it was, therefore, unnecessary to process gearing abbreviations as a separate American Standard. The number of abbreviations used in gearing has intentionally been kept very small to permit memorizing without the need to
22、 refer to the standard. AGMAStandard112.04,GearNomenclature(Geometry)Terms,Definitions,Symbolsand Abbreviations, was a complete revision and integration of the three standards previously mentioned. Because of the widespread acceptance of the previous standards, changes werekepttoaminimum. Thestandar

ItwasapprovedbyStandardsCommitteeB6,Gears,theCo-Secretariatsand the American National Standards Institute on February 3, 1976 and designated
