If anyone should ever need convincing
that the state of American manufacturing is in ongoing decline, consider this: the state of Michigan has the highest concentration of engineers in the country, yet also has the highest unemployment rate. But there are ripples of hope out there as grassroots and otherwise organized groups are fighting the good fight in an attempt to reverse that trend.
Beveloid gears are used to accommodate a small shaft angle. The manufacturing technology used for beveloid gearing
is a special setup of cylindrical gear cutting and grinding machines. A new development, the so-called Hypoloid
gearing, addresses the desire of gear manufacturers for more freedoms. Hypoloid gear sets can realize shaft angles between zero and 20° and at the same time, allow a second shaft angle (or an offset) in space that provides the freedom to connect two points in space.
"One of the reasons AGMA has been
successful over our 93-year history is
that the association’s agenda, programs
and activities reflect the voices of our members," says Joe T. Franklin, Jr., AGMA President.
Sure, Gear Expo undoubtedly has a ton to offer attendees in education, research and networking alone, but what really draws the crowd in are the
physical products and technology on
display from exhibitors. Otherwise it
would just be another technical meeting
or social reception—and AGMA could save a few bucks on space to say the least.
A computational fluid dynamics (CFD) method is adapted, validated and applied to spinning gear systems with emphasis on predicting windage losses.
Several spur gears and a disc are studied. The CFD simulations return good agreement with measured windage power loss.
