AGMA 298.01-75

CNCL S/S BY AGMA 6025

This standard is limited to gearmotors designed and rated inaccordance with Standard AGMA 460.05, “Practice for GearmotorsUsing Spur, Helical, Herringbone and Spiral Bevel Gears,” orin-line reducers and increasers designed and rated in accordancewith Standard AGMA 420.04, “Practice for Enclosed Speed Reducers orIncreasers Using Spur, Helical, Herringbone and Sprial BevelGears.”

This standard is limited to gears operating at a maximum pitchline velocity of 5000 fpm and a maximum speed of 3600 rpm.

This standard includes the instrumentation and procedurenecessary for the determination of the gear unit sound level oroctave band sound pressure levels.

Compliance with this standard does not constitute a warranty ofthe measured gear unit sound levels under installed field serviceconditions.

This standard covers only those gear units which are lubricatedin accordance with manufacturer’s recommendations and tested in asystem of connected rotating parts free from serious criticalspeeds, torsional vibrations and overloads.

Purpose

There is a need in the gear industry for a sound standard forindustrial gear units to improve communication and understandingbetween the gear unit manufacturer and purchaser. The purpose ofthis standard is to present the instrumentation and procedure to beused for sound measurements of gearmotors and in-line reducers andincreasers as well as to present typical maximum sound levels(A-weighted sound pressure levels). Definitions used in thisstandard are given in Appendix A.
