Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests.

16、is document are provided for informational purposes only and are not to be construed as a part of ANWAGMA Standard 6000-896, Specification for Measurement of Linear vibration on Gear Units. ANWAGMA 6000-A88 included and superseded the information previously published in AGMA 426.01 (1 972), Specific

17、ation for Measurementof Lateral Vibration on High Speed Helical and Herringbone Gear Units. Performance of driven equipment is dependent upon the individual characteristics of the prime mover, gear unit, driven machine and support structure, as well as their combined effects as a system. The proper

18、assessment of performance characteristics is essential for realistic evaluation. The knowledge and judgment required to properly evaluate the gear unit vibration comes primarily from years of accumulated experience in designing, manufacturing, and operating gear units. For these reasons, the use of

19、this standard and the evaluation of test results for specific gear product applications should only be attempted by experienced personnel. The complexity of gear vibration phenomena makes most vibration standards difficult to apply or to properly interpret. The AGMA Acoustical Technology Committee d

20、eveloped the Specification for Measurement of Linear Vibration on Gear Units to provide a common basis for communication between project engineers, gear manufacturers, and users. The purpose was, also, to encourage the maximum practical degree of uniformity and consistency among vibration measuremen

21、t practices within the gear industry. Because of the wide variation of gear driven systems and structural supports, ANSi/AGMA 6000-A88 identified certain areas where special considerations might be necessary and must be agreed upon between purchaser and gear manufacturer when discussing gear vibrati

22、ons. ANWAGMA 6000-A88 was approved as a standard by the AGMA membership in May 1988 and approved as an American National Standard on June 16,1988. AN WAGMA 6000-B96 is a revision of AN Si/AGMA 6000-A88. The revision includes clarification of application of the standard, changes to annex A, and the a

23、ddition of a new annex C, from IS0 8579-2. ANWAGMA 6000-896 was approved as a standard by the AGMA membership in June 1996, and approved as an American National Standard on September 6, 1996.

31、 Units 1 Scope This standard presents a method for measuring steady state filtered linear vibrations of a gear unit. Types of instrumentation, measurement methods, and testing procedures for the determination of linear vibration levels for specific types of gear units are provided. Vibration limits

32、at discrete frequencies are recommended for acceptance testing. It is not the intent of this standard to provide unfiltered limits. The recommended limits and conditions specified herein are intended as the vibration criteria for performance of the gear drive during the equipment manufacturers test

33、when specifically agreed to by the manufacturer and purchaser. This standard is specifically applicable to enclosed speed reducing or increasing gear drive units designed, rated, and lubricated in accordance with AN SI/AGMA product standards as indicated in 4.3. This standard does not apply to integ

34、rated systems, shaft-mounted units, special or auxiliary drive trains or power take-off gears. Vibration amplitudes exceeding the recommendations of this specifica- tion for drives with flexible housings or on flexible supports may also be allowable if accounted for in the design. Acceptable limits

35、for this type of equipment should be independently specified. However, if negotiated, this standard may be applied to such equipment. Torsional and transient vibrations of a geared system are not included in this standard. NOTE: Compliance with this standard does not constitute a warranty of the mea

36、sured gear units performance under installed field service conditions. Five annexes are for reference only and are not a part of this standard. Annex A illustrates the relationship between vibratory displacement, velocity and acceleration waveforms. Annex B discusses systems effects and responsibili

37、ty. Annex C presents five classes of gear unit vibration rating and a subjective procedure for selecting the proper rating based on the application and transmitted power. Annex D gives the conversion of metric, SI units to non-metric (inch) units. Annex E contains a bibliography. 2 References The fo
