Acceptance code for gears — Part 2: Determination of mechanical vibrations of gear units during acceptance testing

Specifies the methods for determining mechanical vibration of individually housed, enclosed, speed-increasing and speed-reducing gear units. Specifies methods for measuring housing and shaft vibrations, and the types of instrumentation, measurement methods and testing procedures for determining vibration levels. Vibration grades for acceptance are included. Applies only to a gear unit under test and operating within its design speed, load, temperature range and lubrication for acceptance testing at the manufacturer's facility.
