[url "http://www.facegearss.com/"][#800080][size 3]Face gear[/size][/#800080][/url][#333333][size 3] is a special kind of bevel gear which end face is cut to a tooth shape, and it’s top cone angle and root cone angle is 90 degrees. The paired gears are the ordinary spur or helical cylindrical gear, and their axis angle is 90 degrees. And the[/size][/#333333][url "http://www.facegearss.com/"][#800080][size 3] face gear[/size][/#800080][/url][#333333][size 3]’s meshing angle is changing, near the end of small diameter the meshing angle is small, and near the end of large diameter the meshing angle is large. but the height of all gear surface is the same. Tooth surface are basically straight. Effective width of teeth in the end is restricted by the tooth surface cutting interference, in the outer end is restricted by the the addendum pointing constraints.
Cylindrical gear and face gear has some certain advantages than ordinary bevel gear transmission, that is the pinion assembly can be moved along the axial adjustment without affecting contact and gap, only work for one assembly dimension accuracy. There is no axial strength in the small gear. You can use round bar or ball to detect [/size][/#333333][url "http://www.facegearss.com/"][#800080][size 3]face gear[/size][/#800080][/url][size 3][#333333] tooth thickness.[/#333333][/size]
