These are skew bevel wheels, made of a hyperboloid of revolution around an axis.

Sliding Contact

These are skew bevel wheels, made of a hyperboloid of revolution around an axis.

The lines of contact are equal, but the axes are neither parallel to each other, or the line of contact.

Lateral Sliding Contact

The lines of contact are equal, but the axes are neither parallel to each other, or the line of contact.
