Straight bevel · AGMA 2005
m 2.2 · 20° · straight, AGMA 2005 proportions
The 15 : 45 pair (module 2.2, 3 : 1) with AGMA 2005's mid-face proportions.
Sample · m 2.2 · 20° · hypoid, pinion left hand
Hypoid · offset pinion
The pinion moved off the gear's axis: a bigger, stronger pinion, as in car axles.
