I am still looking for some software that will produce various forms of circular arc gears, that I can subsequently import into solidworks.
@mfgenggear: no offense, but I am having trouble discerning your comments. The accuracy requirement on my end is whatever will work in the chosen application. I am planning on using hydrodynamic bearings, and want to insure that any subsequent center-to-center deltas or errors are tolerable by the chosen circular arc gear.
I am aware that these types of gears are mostly made in Russia and China, and not in the U.S. That is one of the reasons I am here seeking information from people in the industry. Often a design may be rejected due to politics or the "not invented here" syndrome, and I do not want to overlook what may be a practical, superior alternative to standard involute tooth profile gears for those reasons.
