This Standard specifies the methods for determining mechanical vibration of individually housed, enclosed, speed-increasing and speed-reducing gear units. It specifies methods for measuring housing and shaft vibrations, and the type of instrumentation, measurement methods and testing procedures for determining vibration levels. Vibration grades for acceptance are included. It does not include torsional vibration measurements of a geared system. This Standard applies only to a gear unit under test and operating within its design speed, load. temperature range and lubrication for acceptance testing at the manufacture's facility, The gear unit may be tested at another location if agreed upon and operated in accordance with the manufacture's recommendations. Other International Standards on vibration evaluation may be required for measuring gear unit vibration in field service. This Standard does not apply to special or auxiliary drive trains, such as integrated gear-driven compressors, pumps, turbines, etc., and power take-off gears.
