A look at several American organizations doing cutting edge gear-related research for aerospace applications.
It is said that â€śThe squeaky wheel gets the grease.â€ť Ok, but what about gear noise? We talked to three experts with considerable knowledge and experience in this area.
When, in 1980, OSU professor Donald R. Houser created the Gear and Power Transmission Research Laboratory - then known as the Gear Dynamics and Gear and Power Transmission Laboratory (GearLab) - he did so with the seed money provided by just three companies. Thirty-three years out, the lab has continued to grow, impress andâ€”most importantly - succeed; it now boasts a roster of some 50 sponsoring companies and government agencies.
A finite elements-based contact model is developed to predict load distribution along the spline joint interfaces; effects of spline misalignment are investigated along with intentional lead crowning of the contacting surfaces. The effects of manufacturing tooth indexing error on spline load distributions are demonstrated by using the proposed model.
More than 1,350 engineers and technicians have attended the basic course at Ohio State's GearLab.
