Welcome to GearLab

The Gear and Power Transmission Research Laboratory, formerly the Gear Dynamics and Gear and Power Transmission Laboratory, is a research group at The Ohio State University in Columbus, Ohio, dedicated to aiding sponsoring industries and government agencies by

  • enhancing gear and power transmission technology through fundamental and applied research and transfer research results
  • providing graduate and under graduate students with applied educational and research opportunities in gear and power transmission related disciplines, and
  • keeping sponsors updated on latest gear and transmission technologies.

Research Focus

The research portfolio of the GearLab is formed by a number basic and applied research projects designed to develop new technologies and validated methods towards aiding one or more of the common goals of its sponsors, including:

  • increasing power density,
  • improving quality,
  • reducing noise and vibration,
  • improving efficiency and lubrication, and
  • reducing cost

of power transmission and gear systems. With application to gear and power transmission systems, GearLab’s research projects fall in a number of mechanical engineering disciplined including

  • geometry, kinematics, design and analysis,
  • dynamics, vibrations, acoustics and noise control,
  • contact mechanics, load distribution models and FEA,
  • power losses and efficiency,
  • contact and bending fatigue,
  • engineered surfaces, wear, lubrication and tribology, and
  • metrology and test methodologies.
