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.

Types of instrumentation, measurement methods, and testing procedures for the determination of linear vibration levels for specific types of gear units are provided. 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.
So that is one thing against you in developing a simple formula.

Annex C presents five classes of gear unit vibration rating and a subjective procedure for selecting the proper rating based avma the application and transmitted power.

Does anybody knows how to calculate acceleration vibration limits for the extracted amplitudes of a frequency spectrum? 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.
Annex A illustrates the relationship between vibratory displacement, velocity and acceleration waveforms. However, if negotiated, this standard may be applied to such equipment. Membership Required We’re sorry. The revision includes clarification of application of the standard, changes to annex A, and the addition of a new annex C, from ISO Like Reply 0 Likes.

Finally, you’ll never receive email notifications about content they create or likes they designate for your content. Zuber, there is a possibility that once you do some conversions, you might be able to trace this to some limits from within an ISO spec from the same timeframe to about I can’t say for sure, since I don’t have ready access to the specs from that period.
The complexity of gear vibration phenomena makes most vibration standards difficult to apply or to properly interpret. Annex D gives the conversion of metric, Aggma units to non-metric inch units.
Quantity must be a positive whole agmz. Thank you Olov ;- Nino. The next thing is you’ll notice a “kink” at Hz or slightly above depending on A or B that also presents a problem.
Hi Nino, Welcome to the board. SCOPE This standard presents a method for measuring steady state filtered linear vibrations of a gear unit. Acceptable limits for this type of equipment should be independently specified. Five annexes are for reference only and are not a part of this standard. Suggestions for improvement of this standard will be welcome.
The proper assessment of performance characteristics is essential for realistic evaluation. For these reasons, the use of this standard and the evaluation 6000-g96 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.
The purpose was, also, 600-0b96 encourage the maximum practical degree of uniformity and consistency among vibration measurement practices within the gear industry. 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.
It is not the intent of this 6000-bb96 to provide unfiltered limits.

Torsional and transient vibrations of a geared system are not included in this standard. Annex B discusses systems effects and responsibility.
Performance 0600-b96 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.

This standard does not apply to integrated systems, shaft-mounted units, special or auxiliary drive trains or power take-off gears.
