Acceptance code for gears -- Determination of mechanical vibrations of gear units during acceptance testing

BSI BS 7676-2:1993

1.1 This part of ISO 8579 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 types 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 part of ISO 8579 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.

The gear unit may be tested at another location if agreed upon and operated in accordance with the manufacturer’s recommendations.

Other International Standards on vibration evaluation may be required for measuring gear unit vibration in field service.

This part of ISO 8579 does not apply to special or auxiliary drive trains, such as integrated gear-driven compressors, pumps, turbines, etc., and power take-off gears.

NOTE 1 Acceptance limits for tests of these types of equipment should be independently specified. However, if negotiated, this or other appropriate standards may be applied to such equipment.

1.2 Special provisions may be required for vibration measurements: the type of measurement and acceptance level should therefore be agreed between the manufacturer and purchaser at an early stage of negotiation.
