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.

Define the range on the depicted curves where you operate and then see what you can do with some ayma fitting routine. SCOPE This standard presents a method for measuring steady state filtered linear vibrations of a gear unit. Annex A illustrates the relationship between vibratory displacement, velocity and acceleration waveforms.
ANSI/AGMA B96 (R) – Specification for Measurement of Linear Vibration on Gear Units
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. The next thing is you’ll notice a “kink” at Hz or slightly above depending on A or B that also presents a problem. Quantity must be a positive whole number. Does anybody knows how to calculate acceleration vibration limits for the extracted amplitudes of a frequency spectrum?
Block When you block a person, they can no longer invite you to a private message or post to your profile wall.
I can’t say for sure, since I don’t have ready access to the specs from that period. 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. Manage Follow Preferences Loading 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 agna system.
Five annexes are for reference only and are not a part of this standard. Like Reply 0 Likes. The purpose was, also, to encourage the maximum practical degree of uniformity and consistency among vibration measurement practices within the gear industry.

The revision includes clarification of application of the standard, changes to annex A, and the addition of a new annex C, from ISO The knowledge and judgment required to properly evaluate the gear unit vibration comes primarily 6000-bb96 years of accumulated experience in designing, manufacturing, and operating gear units.
Types of instrumentation, measurement methods, and testing procedures for the determination of linear vibration levels for specific types of gear units are provided.
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. However, if negotiated, this standard may be applied to such equipment. Finally, you’ll never receive email notifications about content they create or likes they designate for your content. 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.
Annex B discusses systems effects and responsibility. Hi Nino, Welcome to the board. 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 Vibration limits at discrete frequencies are recommended for acceptance testing.
The proper assessment of performance characteristics is essential for realistic evaluation. Membership Required We’re sorry. Sign In or Register. Acceptable limits for this type of equipment should be independently specified.
You must be signed in to continue.
The complexity of gear vibration phenomena makes most vibration standards difficult to apply or to properly interpret. Annex E contains a bibliography.
So that is one thing against you in developing a simple formula. Annex D gives the conversion of metric, SI units to non-metric inch units.
