Gear Systems Design for Minimum Noise
The need for noise control and its relation to gear drive design will be discussed. The general nature of noise and its measurement will be examined, with particular emphasis on terminology standards, and units of measurement appropriate to gear technology. Gear noise, per se, is seldom heard by and observer. The mechanism by which observer noticed noise is generated and transmitted will be defined, described, discussed. Before attempting to solve a noise problem with an existing unit or beginning the design of a new unit, the nature of the noise must be defined. Both experimental and analytical methods will be covered, with particular emphasis on application rather than theory.The many factors that influence the noise produced by a gear system will be discussed. The relative effects of each factor will be studied qualitatively. Factors to be considered include gear tooth geometry and accuracy, speed, materials, housing design, bearing type, gear type, air entrapment, root clearance, interference alignment, surface finish, and phasing. Although, ideally, the designer should solve noise problems on the drawing board, in the real world this sometimes does not occur. Various techniques that can reduce the noise level of existing gear systems without requiring major hardware replacement will be presented and discussed. Included in the discussion will be enclosures, absorbers, dissipative dampers, isolators (gearbox and gear blank), and impulse phasing.

How Many CEUs Will I Earn?
As an IACET-accredited provider, AGMA offers 1.3 CEUs for this class.
- Understand the need for gearbox system noise control and, especially, the difference between “gear noise” and “gearbox system noise”.
- Become familiar with the “nature” of noise and its measurement as well as terminology standards, and units of measurement appropriate to gear technology.
- Learn the mechanisms by which observer noticed noise is generated and transmitted.
- Gain a knowledge of the experimental and analytical methods for measuring noise, with particular emphasis on application rather than theory.
- Explain the importance of equal planet/star gear spacing and how a system can be designed with unequal planet spacing.
- Understand the various design and manufacturing factors that influence gear system noise including gear tooth geometry and accuracy, speed, materials, housing design, bearing type, gear type, air entrapment, root clearance, interference alignment, surface finish, and phasing.
- Recognizing that it is often necessary to address noise issues after the gearbox system is designed, learn how enclosures, absorbers, dissipative dampers, isolators (gearbox and gear blank), and impulse phasing can be applied to existing systems to reduce noise level.
Who Should Attend
Gear and gearbox design and quality control engineers involved with design and manufacture of gear systems used in applications where noise is of special concern such as medical equipment, electric vehicles, and any other application where the level and/or character of the noise emitted by the gear system is of significant concern.

Raymond J. Drago, P.E.
Raymond J. Drago is Chief Engineer of Drive Systems Technology, Inc. (DST), a mechanical power transmission consulting organization that he founded in 1976. Mr. Drago also worked for the Boeing Company – Helicopters Division until his retirement after 37 years of service. Currently Mr. Drago is involved in the analysis, design, manufacture, assembly, and testing of many gear systems. In his role with DST, Mr. Drago is active in all areas of mechanical power transmission, including the design and analysis of drive systems in a very diverse field of application from heart pumps to very large mining & mill gears. He has used his 53 years of gear technology experience to prepare and deliver more than 150 Technical Papers and 339 courses dealing with various aspects of gear design and analysis.
I started working at Boeing in 1967 and continued until my retirement in 2004. I started Drive Systems Technology in 1976 as a part time activity while still working at Boeing (with Boeing’s knowledge and approval, under strict guidelines) which eventually grew to the point where I retired early from Boeing in order to pursue DST as a full-time activity.
