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.

The complexity of gear vibration phenomena makes most vibration standards difficult to apply or to properly interpret. Finally, you’ll never receive email notifications about content they create or likes they designate for your content. Membership Required We’re sorry. The next thing is you’ll notice a “kink” at Hz or slightly above depending on A or B that also presents a problem.
ANSI/AGMA B96 (R) – Specification for Measurement of Linear Vibration on Gear Units
Suggestions for improvement of this standard will be welcome. The revision includes clarification of application of the standard, changes to annex A, and the addition of a new annex C, from ISO However, if negotiated, this standard may be applied to such equipment. The purpose was, also, to encourage the maximum practical degree of uniformity and consistency among vibration measurement practices within the gear industry.
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.
Quantity must be a positive whole number. It is not the intent of this standard to provide unfiltered limits. Define the range on the depicted curves where you operate and then see agms you can do with some curve fitting routine. Annex D gives agmma conversion of metric, SI units to non-metric inch units. 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.
Thank you Olov ;- Nino.

Vibration limits calculation according to the ANSI/AGMA 6000-B96 | AMP Maintenance Forums
Performance agka 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.
Vibration amplitudes exceeding the recommendations of this specification for drives with flexible housings or on flexible supports may also be allowable if accounted 60000-b96 in the design. John from PA Leader. Vibration limits at discrete frequencies are recommended for acceptance testing. Annex B discusses systems effects and responsibility.

Sign In or Register. Hi Nino, Welcome to the board.
Block When you block a person, they can no longer invite you to 600-b96 private message or post to your profile wall. 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.
This standard does not apply to integrated systems, shaft-mounted units, special or auxiliary drive trains or power take-off gears.
Five annexes are for reference only and ahma not a part of this standard. 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.
Torsional and transient vibrations of a geared system are not included in this standard.
Types of instrumentation, measurement methods, and testing procedures for the determination of linear vibration levels for specific types of gear units are provided.
Annex E contains a bibliography. 6000-v96, 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 60000-b96 Does anybody knows how to calculate acceleration vibration limits for the extracted amplitudes of a frequency spectrum? You must be signed in to continue. Annex A illustrates the relationship between vibratory displacement, velocity and acceleration waveforms.
