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.

Torsional and transient vibrations of a geared system are not included in this standard. 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.
John from PA Leader. 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. Vibration limits at discrete frequencies are recommended for acceptance testing.
Annex B discusses systems effects and responsibility. You must be signed in to continue. Annex C presents five classes of gear unit vibration rating and a subjective procedure for selecting agmw proper rating based on the application and transmitted power.
Annex E contains a bibliography. Originally posted by John from PA: SCOPE This standard presents a method for measuring steady state filtered linear vibrations zgma a gear unit. I can’t say for sure, since I don’t have ready access to the specs from that period. Finally, you’ll never receive email notifications about content they create or likes they designate for your content.

Sign In or Register. Acceptable limits for this type of equipment should be independently specified. However, if negotiated, this standard may be applied to such equipment.
The complexity of gear vibration phenomena makes most vibration standards difficult to apply or to properly interpret. Thank you Olov ;- Nino. Block When you block a person, they can no longer invite you to a private message or post to your profile wall. So that is one thing against you in developing a simple formula. 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.

Vibration limits calculation according to the ANSI/AGMA 6000-B96 | AMP Maintenance Forums
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 Types of ama, measurement methods, and testing procedures for the determination of linear vibration levels for specific types of gear units are provided.
This standard does not apply to integrated systems, shaft-mounted units, special or auxiliary drive trains or power take-off gears. Annex A illustrates the relationship between vibratory displacement, velocity and acceleration waveforms.
Agmx Required We’re sorry.

It is not the intent of this standard to provide unfiltered limits. The purpose was, also, to encourage the maximum practical degree of uniformity and consistency among vibration measurement practices within the gear industry.
6000-g96 proper assessment of performance characteristics is essential for realistic evaluation. Hi Nino, Welcome to the board.
Define the range on the depicted curves where you operate and then see what you can do with some curve fitting routine. The revision includes clarification of application of the standard, changes to annex A, and the addition of a new annex 60000-b96, from ISO Annex D gives the conversion of metric, SI units to non-metric inch units.
The next thing is you’ll notice a “kink” at Hz or slightly above depending on A or B that also presents a problem.
Performance of driven equipment is dependent upon the individual characteristics of agna prime mover, gear 6000-b996, driven machine and support structure, as well as their combined effects as a system. Manage Follow Preferences Loading Quantity must be a positive whole number.
Five annexes are for reference only and are not a part of this standard. 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.
