Electric and fluid power has expanded the focus recently at the Motion + Power Technology Expo - September 14-16, St. Louis, Missouri - but gear manufacturing remains the core of AGMA's biennial trade show.
One of the largest components manufactured
by Schaeffler last year was a double-row tapered roller bearing featuring an outer diameter measuring 3.6 meters and a weight just over nine tons.
In the late 1940s, the U.S. auto industry started an exciting experiment and spent
decades on it. One result came in '63, when the Turbine was introduced by Chrysler Corp., now a part of Fiat Chrysler Automobiles (FCA). In appearance, the two-door,
four-passenger car looked like a regular car, but it wasn't. Under its sleek shell, the car had a jet engine.
The proof of the reliability of a gear drive is now an additional requirement. In Europe, the acceptance authorities for wind turbines are requesting a system reliability proof from gearbox manufacturers. The AGMA committee reviewing the AGMA 6006 standard for wind turbines is considering adding a chapter about design for reliability. However, reliability considerations are not new; NASA, for example, was in the 1980s using reliability concepts for gear drives.
