ANSIAGMAB96RSpecification for Measurement of Linear Vibration on Gear Units-. AGMA B96 (R). Specification for Measurement of Linear Vibration on Gear Units. standard by American Gear Manufacturers. The ANSI/AGMA B96 give the acceleration limits VS frequency chart but I need to have an exact formula in order to calculate these limits.

Membership Required We’re sorry. Annex B discusses systems effects and responsibility. Note as well in interpreting the AGMA spec, the preferred units are in g’s peak so any comparison to a different spec will have to take units into account. 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.
Manage Follow Preferences Loading Does anybody knows how to calculate acceleration vibration limits for the extracted amplitudes of a frequency spectrum? For these reasons, the use of this standard and the evaluation of test results for specific gear product applications should only be attempted by experienced personnel.
Define the range on the depicted curves where you operate and then see what you can do with some curve fitting routine. You must be signed in to continue.
Annex D gives the conversion qgma metric, SI units to non-metric inch units. So that is one thing against you in developing a simple formula. Vibration amplitudes exceeding the recommendations of this specification for drives with flexible housings or on flexible supports may also be allowable if accounted for in the design. Thank you Olov ;- Nino.

The revision includes clarification of application of the standard, changes to annex A, and the addition of a new annex C, from ISO The purpose was, also, to encourage the maximum practical degree of uniformity and consistency among vibration measurement practices within the gear industry.
Vibration limits at discrete frequencies are recommended for acceptance testing. Annex E contains a bibliography. It is 6000-v96 the intent of this standard to provide unfiltered limits.

The next thing is you’ll notice a “kink” at Hz or slightly above depending on A or B that also presents a problem. I can’t say for sure, since I don’t have ready access to the specs from that period.
Torsional and transient ahma of a geared system are not included in this standard. Suggestions for improvement of this standard will be welcome.
Acceptable limits for this type of equipment should be independently specified. Zuber, there is a possibility that once you do some conversions, you might be able to trace this to some limits from within 6000b-96 ISO spec from the same timeframe to about Finally, you’ll never receive email notifications about content they create or likes they designate for your content.
The proper assessment of performance characteristics is essential for realistic evaluation. 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.

This standard does not apply to integrated systems, shaft-mounted units, special or auxiliary drive trains or power take-off gears. Block When you block a person, they can no longer invite you to a private message or post to your profile wall. 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.
SCOPE This standard presents a method for measuring steady state filtered linear vibrations of a gear unit.
