The geometric arrangements described thus far enable motion transmission between parallel and skew axes, and they do so with line contact. The important case of intersecting axes seems to be excluded. However, to recover this case, only one additional rotation needs to be introduced, namely, a relative rotation between the pinion and the gear about an axis belonging to the common plane of action and directed as the generating plane's normal **n**_{Π}. With reference to Fig. 9, we apply such rotation to the pinion blank and call it *spin*. It is parameterized by the angle *σ*, positive if concordant with the unit vector **n**_{Π}. After skewing the pinion and gear axes through *δ*_{p} and *δ*_{g}, intersecting axes can be obtained by spinning the pinion axis through a suitable angle *σ*. This operation has an important implication, namely, that the two planes of action are not coincident any more. They now intersect at a line, parallel to **n**_{Π}, and along which contact evolves: the *line-of-action*. As a result, *line contact* is changed into *point contact*, but *conjugality is not affected*. This contact localization should not cause too much concern; indeed, microgeometry corrections (e.g., profile and lead crowning) change line contact into point contact. Obviously, this localization effect should not be too severe in order to avoid large contact stresses which penalize load-carrying capacity. In Sec. 3.4, the claims made here will be demonstrated analytically using the TCA tools already employed for spur gears.
