TheformerAGMA390.02 for Coarse-Pitch and Fine-Pitch Spur, Helical and Herringbone Gearing was

20、enhanced to offer a single, compatible classification system. The tolerance identifier Qwas added to indicate that the tolerances in 390.03 apply. If Q is not used as a prefix in thequality number, tolerances in AGMA 390.01 and 390.02 applied.ANSI/AGMA 2000-A88 was an update of those sections from A

21、GMA 390.03 for parallelaxis gears only. Additionally, the formulas stated the tolerances in metric terms. Thecontent was revised, but basic tolerance levels were unchanged from AGMA 390.03. Theother material in AGMA 390.03 on Bevels and Worms was replaced by ANSI/AGMA2009-A99 and ANSI/AGMA 2011-A98,

22、 respectively. ANSI/AGMA 2000 was approved byAGMAmembershipinJanuary1988,andasaAmericanNationalStandardInstitute(ANSI)standard on March 31, 1988.The user of thisAmerican NationalStandard isalerted thatdifferences existbetween itandANSI/AGMA 2000-A88. Differences include, but are not limited to:- Acc

23、uracy grade numbering system is reversed, such that the smallest numberrepresents the smallest tolerance;- Relative magnitudes of elemental tolerances for a single grade are in a differentproportion;- Thehelixevaluationrange,where thetolerances areapplied, aredefined forlessflank area than in ANSI/A

24、GMA 2000-A88;- The K Chart is not used for the permissible tolerance values;- Runout is not included as one of the elements with a tolerance;- Concepts of mean measurement trace, design profile, slope deviation andform deviation are added, similar to ISO 1328-1.Therefore, the user of ANSI/AGMA 2015-

25、1-A01 must be very careful when comparingtolerance values formerly specified using ANSI/AGMA 2000-A88.Copyright American Gear Manufacturers Association Provided by IHS under license with AGMANot for ResaleNo reproduction or networking permitted without license from IHS-,-,-ANSI/AGMA 2015-1-A01AMERIC

26、AN NATIONAL STANDARDvANSI/AGMA 2015-1-A01 is a replacement for ANSI/AGMA 2000-A88 and ANSI/AGMAISO 1328-1. It is a complete revision, including accuracy grades, in order to be morecompatible with ISO. It combines the grading system of ISO 1328-1 with the methods ofANSI/AGMA 2000-A88, and adds concep

27、ts of accuracy grade grouping for minimummeasurementrequirements,filtering,datadensity,androughnesslimitstoformdeviations.This revision was started by the AGMA Inspection and Handbook Committee in 1997. Itwas approved by the AGMA membership in June, 2001. It was approved as an AmericanNational Stand

28、ard on August 1, 2002.Suggestions for improvement of this standard will be welcome.
