It is used for rotation transmission between the shafts, relative position of which in space is arbitrary.
- Yellow part is connected to the input pink shaft via 3 point-on-plane joints.
- Yellow part is connected to the output blue shaft via a point-on-line joint and 2 point-on-plane joints.
The simulation shows that it is a constant velocity joint.
The video shows case when the shafts intersect with one another at angle of 20 deg.
