Recent breakthroughs in profile grinding software are helping Anderson Precision Gears and others meet wind power’s insatiable appetite for faster
production of large, high-quality gears.
“The gear marketplace is a global marketplace.” Bill Bradley says it easily, with no special emphasis. The vice president of AGMA’s technical division sees the statement as an obvious fact.
As the international business community grows closer together, the
need for understanding differences between national and international
gear rating standards becomes increasingly important for U.S. gear
manufacturers competing in the world market.
AGMA has started to replace its 2000-A88 standard for gear accuracy with a new series of documents based largely on ISO standards. The first of the replacement AGMA standards have been published with the remainder coming in about a year. After serving as a default accuracy specification for U.S. commerce in gear products for several decades, the material in AGMA 2000-A88 is now considered outdated and in need of comprehensive revision.
The seemingly simple process of placing a uniform chamfer on the face ends of spur and helical gears, at least for the aerospace industry, has never been a satisfactory or cost effective process.
