scope:

This standard presents a method for measuring steady state vibration of 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.

The recommended limits and conditions specified herein are intended as the vibration criteria for performance of the gear drive during the equipment manufacturer's test when specifically agreed to by the manufacturer and purchaser.

This standard is specifically applicable to enclosed speed reducing or increasing gear drive units designed, rated, and lubricated in accordance with ANSI/AGMA product standards as indicated in 4.3.

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 should be independently specified. However, if negotiated, this standard may be applied to such equipment.

Torsional and transient vibrations of a geared system are not included in this standard.

NOTE: Compliance with this standard does not constitute a warranty of the measured gear unit's performance under installed field service conditions.
