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.
This standard does not apply to integrated systems, shaft-mounted units, special or auxiliary drive trains or power take-off gears. 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.
Membership Required We’re sorry. Does anybody knows how to calculate acceleration vibration limits for the extracted amplitudes of a frequency spectrum? Sign In or Register.
Vibration limits at discrete frequencies are recommended for acceptance testing. I can’t say for sure, since I don’t have ready access agmx the specs from that period.
Types of instrumentation, measurement methods, and testing procedures for the determination of linear vibration levels for specific types of gear units are provided. The next thing is you’ll notice a “kink” at Hz or slightly above depending on A or B that also presents a problem.
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. 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. Torsional and transient vibrations of a geared system are not included in this standard.

The proper assessment of performance characteristics is essential for realistic evaluation. Annex A illustrates the relationship between vibratory displacement, velocity and acceleration waveforms. John from PA Leader. 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.
The purpose was, also, to encourage the maximum practical degree of uniformity and consistency among vibration measurement practices within the gear industry. So that is one thing against you in developing a simple formula. SCOPE This standard presents a method for measuring steady state filtered linear vibrations of a gear unit.
However, if negotiated, this standard may be applied to such equipment.

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 a system. Hi Nino, Welcome to the board. Zuber, there is a possibility that once you do some conversions, you might be able to 6000-v96 this to some limits from within an ISO spec from the same timeframe to about Annex E contains a bibliography.

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. Annex D gives the conversion of metric, SI units to non-metric inch units. Five annexes are for reference only and are not a part of this standard. The complexity of gear vibration phenomena makes most vibration standards difficult to apply or to properly interpret.
Define the range on the depicted curves where you operate and then see what you can do with some curve fitting routine.
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.
It is not the intent of this standard to provide unfiltered limits.
