Input: green 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 = 45 deg.
- If B = A (this video case) two revolutions of the input correspond one revolution of the output. Output velocity is not constant.
When pink slider axis is in plane containing axes of the two shafts, it is in line with axis of the yellow shaft.
