Input: white shaft.
Output: yellow shaft
It is a spherical mechanism.
Its center is intersecting point of the two shaft axes.
Axes ot the input and output shafts intersect at angle A = 45 deg.
Angle between axes of the input and the pink slider is B = 60 deg.
B is larger than A, one revolution of the input corresponds one revolution of the output. Output velocity is not constant.
