Face gears typically have a straight or skewed tooth line andvarying tooth profile in normal cross section at different radiifrom major to minor diameter. These face gears are engaged withspur or helical involute pinions at intersecting or crossedaxes.
This paper presents spiral face gears with an involute toothline and an identical tooth profile in the normal section at anyradius. There are two main applications for such face gears. One ofthem is an alternative solution with certain advantages inperformance and fabrication technology to the straight tooth,Hirth, or Curvic flange couplings. Another application is when aface gear is engaged with an involute helical pinion or worm atintersecting or crossed axes.
Potential advantages of spiral face couplings and gears includehigh power transmission density and highly productive machining offace spiral gears.
The paper describes gear geometry analysis, and design techniqueof spiral face involute gears with symmetric and asymmetric toothprofiles. It also explains a hobbing method of these gears and tooldesign specifics, and then illustrates gear and tool design withnumerical examples.
