The ISO and AGMA Gear Rating Committees have for several years been comparing the results of different rating methods for several sets of gear pairs that have similar normal sections but different helix angles. The analysis presented...

There is wealth of literature on the subject of single (or uni-) directional gear tooth bending stress and lifte relationships (i.e., S-N curves) that has been published in various journals and handbooks over past decades. Several of...

Seven national metrology institutes comprised of European and non-European member states participated in the implementation of the first international comparison of involute gear standards. Participants include: Germany, China, Japan, Thailand, United Kingdom, Ukraine and USA. This comparison...

In 2001, AGMA introduced the first of two documents ANSI/AGMA 2015--1 --A01, Accuracy Classification System -- Tangential Measurements for Cylindrical Gears followed in 2006 by the release of ANSI/AGMA 2015--2--A06, Accuracy Classification System -- Radial System for...

One possible process for the hard finishing of gears is the continuous generating gear grinding, which has replaced other grinding processes in batch production of small to medium sized gears due to its high process efficiency. Despite...
