Gear Systems Design for Minimum Noise - December 1-3, 2020

Who Should Attend:

Gear design engineers

Management involved with the design and manufacture of gearing type components

Metallurgists and materials engineers

Laboratory technicians

Quality assurance technicians

Furnace design engineers

Equipment suppliers 

Expected Student Learning (Course Level) Outcomes:

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 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.

Raymond Drago, P.E. (Moderator)

Chief Engineer - Gear Technologist, Drive Systems Technology

Raymond J. Drago is Chief Engineer of Drive Systems Technology, Inc. (DST), a mechanical power transmission consulting organization that he founded in 1976. Prior to this, Mr. Drago 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 also prepared and delivered more than 150 seminars dealing with various aspects of gear design and analysis.
