2、an American National Standard requires verification by ANSI that the require-ments for due process, consensus, and other criteria for approval have been met by thestandards developer.Consensus is established when, in the judgment of the ANSI Board of Standards Review,substantial agreement has been r

3、eached by directly and materially affected interests.Substantial agreement means much more than a simple majority, but not necessarily una-nimity. Consensus requires that all views and objections be considered, and that aconcerted effort be made toward their resolution.The use of American National S

Moreover, noperson shall have the right or authority to issue an interpretation of an American NationalStandard in the name of the American National Standards Institute. Requests for interpre-

14、tion on Gear Units.ANSI/AGMA 6000-A88 included and superseded the information previously published inAGMA 426.01 (1972), Specification for Measurement of Lateral Vibration on High SpeedHelical and Herringbone Gear Units.Performance of driven equipment is dependent upon the individual characteristics

15、 of theprime mover, gear unit, driven machine and support structure, as well as their combinedeffects as a system. The proper assessment of performance characteristics is essential forrealistic evaluation. The knowledge and judgment required to properly evaluate the gearunit vibration comes primaril

16、y from years of accumulated experience in designing,manufacturing, and operating gear units. For these reasons, the use of this standard andthe evaluation of test results for specific gear product applications should only be attemptedby experienced personnel.The complexity of gear vibration phenomen

17、a makes most vibration standards difficult toapply or to properly interpret. The AGMA Acoustical Technology Committee developed theSpecification for Measurement of Linear Vibration on Gear Units to provide a common basisfor communication between project engineers, gear manufacturers, and users. Thep

18、urpose was, also, to encourage the maximum practical degree of uniformity andconsistency among vibration measurement practices within the gear industry.Because of the wide variation of gear driven systems and structural supports, ANSI/AGMA6000-A88 identified certain areas where special consideration

19、s might be necessary andmust be agreed upon between purchaser and gear manufacturer when discussing gearvibrations.ANSI/AGMA 6000-A88 was approved as a standard by the AGMA membership in May1988 and approved as an American National Standard on June 16, 1988.ANSI/AGMA 6000-B96 is a revision of ANSI/A

20、GMA 6000-A88. The revision includesclarification of application of the standard, changes to annex A, and the addition of a newannex C, from ISO 8579-2.ANSI/AGMA 6000-B96 was approved as a standard by the AGMA membership in June1996, and approved as an American National Standard on September 6, 1996.

21、Suggestions for improvement of this standard will be welcome.

Vibration limits at di

27、screte frequenciesare recommended for acceptance testing. It is notthe intent of this standard to provide unfiltered limits.The recommended limits and conditions specifiedherein are intended as the vibration criteria forperformance of the gear drive during the equipmentmanufacturers test when specif

28、ically agreed to bythe manufacturer and purchaser.This standard is specifically applicable to enclosedspeed reducing or increasing gear drive unitsdesigned, rated, and lubricated in accordance withANSI/AGMA product standards as indicated in 4.3.This standard does not apply to integrated systems,shaf

29、t-mounted units, special or auxiliary drive trainsor power take-off gears. Vibration amplitudesexceeding the recommendations of this specifica-tion for drives with flexible housings or on flexiblesupports may also be allowable if accounted for inthe design. Acceptable limits for this type ofequipmen

30、t should be independently specified.However, if negotiated, this standard may be appliedto such equipment.Torsional and transient vibrations of a geared systemare not included in this standard.NOTE: Compliance with this standard does notconstitute a warranty of the measured gear unitsperformance und

The gear unit should be tested in a mannerto minimize system effects such as listed in annex B.Acceptab

47、le limits for tests of geared equipmentoutside the scope of this standard should beindependently specified. However, if negotiated,this standard or others may be applied to suchequipment.4.2 System considerationsVibration levels of the gear unit in field service maybe adversely affected by factors n

48、ot under thecontrol of the gear manufacturer, as listed in annexB. Therefore, gear manufacturers cannot be heldresponsible for higher vibration levels resulting fromenvironmental and system influences in fieldinstallation.CAUTION: System effects should be analyzed duringthe initial design stage of a

49、 transmission system. Theresponsibility for this analysis must be clearly definedduring this stage. All system component manufactur-ers should be made aware of this decision onresponsibility.ANSI/AGMA 6000- B96AMERICAN NATIONAL STANDARD34.3 Applicable designsThis standard applies to gear units designedgenerally in accordance with the followingstandards:ANSI/AGMA 6010-E88, Standard for Spur, Helical,Herringbone, and Bevel Enclosed Drives.ANSI/AGMA 6011-G92, Specification for HighSpeed Helical Gear Units.ANSI/AGMA 6017-E86 (R1994), R
