SCOPE This standard presents a method for measuring steady state filtered linear vibrations agmaa a gear unit. Types of instrumentation, measurement methods, and testing procedures for the determination of linear vibration levels for specific types of gear units are provided.
Vibration limits at discrete frequencies are recommended for acceptance testing. It is not the intent of this standard to provide unfiltered limits. This standard does not apply to integrated systems, shaft-mounted units, special or auxiliary drive trains or power take-off gears.
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. Acceptable limits for this type of equipment ayma be independently specified. 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 aagma and support structure, as well as their combined effects as a system.
The proper assessment of performance characteristics is essential for realistic evaluation.
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 6000–b96 gear product applications should only be attempted by experienced personnel.

The complexity of gear vibration phenomena makes most vibration standards difficult to apply or to properly interpret. 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 Suggestions for improvement of this standard will be welcome. Torsional and transient vibrations of a geared system are not included in this standard.
ANSI/AGMA B96 (R) – Specification for Measurement of Linear Vibration on Gear Units
Five annexes are for reference only and are not a part of this standard. Annex A illustrates the relationship between vibratory displacement, velocity and acceleration waveforms.
Annex B discusses systems effects and responsibility. 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 D gives the conversion of metric, SI units to non-metric inch units. Annex E contains a bibliography. Quantity must be a positive whole number.
