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.

Acceptable limits for this type of equipment should be independently specified. You must be signed in to continue. 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 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.
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. 6000-b9, you’ll never receive email notifications about content they create or likes they designate for your content. I can’t say for sure, since I don’t have ready access to the specs from that period.

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. 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.
The revision includes clarification of application of the standard, changes to annex A, and the addition of a new annex C, from ISO Vibration limits at discrete frequencies are recommended for acceptance testing. So that is one thing against you in developing a simple formula. Suggestions for improvement of this standard will be welcome.
Torsional and transient vibrations of a geared system are not included in this standard. Originally posted by John from PA: Like Reply 0 Likes. Thank you Olov ;- Nino. 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 agam.

The purpose was, also, to encourage the maximum practical degree of uniformity and consistency among vibration measurement practices within the gear industry. This standard does not apply to integrated systems, shaft-mounted units, special or auxiliary drive trains or power take-off gears.
Does anybody knows how to 6000b-96 acceleration vibration limits for the extracted amplitudes of a frequency spectrum? Types of agmz, measurement methods, and testing procedures for the determination of linear vibration levels for specific types of gear units are provided.
Annex D gives the conversion of metric, SI units to non-metric inch units. Hi Nino, Welcome to the board. The proper assessment of performance characteristics is essential for realistic evaluation. Sign In or Register. Block When you block a person, they can no longer invite you to a private message or post to your profile wall. Quantity must be a 60000-b96 whole number.
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 A illustrates the relationship between vibratory displacement, velocity and acceleration waveforms. Membership Required We’re sorry. It is not the intent of this standard to provide unfiltered limits. However, if negotiated, this standard may be applied to such equipment.

John from PA Leader. Annex E contains a bibliography.
The next thing is you’ll notice a “kink” at Hz or slightly above depending on A or B that also amga a problem. SCOPE This standard presents a method for measuring steady state filtered linear vibrations of a gear unit.
