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.

You must be signed in to continue. John from PA Leader. Define the range on the depicted curves where you operate and then see what you can do with some curve fitting routine.
Annex D gives the conversion of metric, SI units to non-metric inch units.
However, if negotiated, this standard may be applied to such equipment. Does anybody knows how to calculate acceleration vibration limits for the extracted amplitudes of a frequency spectrum? Originally posted by John from PA: It is not the intent of this standard to provide unfiltered limits. atma

Vibration limits at discrete frequencies are recommended for acceptance testing. 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. Zuber, there is a possibility that once you do some conversions, you might be able to trace this to some agmq 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 proper assessment of performance characteristics is essential for realistic evaluation. SCOPE This standard presents a method for measuring steady state filtered linear vibrations of a gear unit.
The purpose was, also, to encourage the maximum practical degree of uniformity and consistency among vibration measurement practices within the gear industry. Hi Nino, Welcome to the board. Acceptable limits for this type of equipment should be independently specified. Annex 6000b96 illustrates the relationship between vibratory displacement, velocity and acceleration waveforms. 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.
Performance of driven equipment agmz 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. Thank you Olov ;- Nino. The complexity of gear vibration phenomena makes most vibration standards difficult to apply or to properly interpret.
So that is one thing against you in developing a simple formula. The revision includes clarification of application of the standard, changes to annex A, 6000b-96 the addition of a new annex C, from ISO Finally, you’ll never receive email notifications about content they create or likes they designate for your content.

Suggestions for improvement of this standard will be 6000-n96.

Block When you block a person, they can no longer invite you to a private message or post to your profile wall. 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.
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. Annex B discusses systems effects and responsibility. Types of instrumentation, measurement methods, and testing procedures for the determination of linear vibration levels for specific types of gear units are provided.
Five annexes are for reference only and are not a part of this standard. This standard does not apply to integrated systems, shaft-mounted units, special or auxiliary drive trains or power take-off gears.
Quantity must be a positive whole number. Like Reply 0 Likes. 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.
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. Annex E contains a bibliography. Torsional and transient vibrations of a geared system are not included in this standard.
