Screw 3-stage telescopic actuator
Input: yellow screw.
Green slider has the green nut that together with the input screw create the first screw-nut drive.
Pink slider of inner thread and the orange screw create the second screw-nut drive.
Jade slider of inner thread and the beige screw create the third screw-nut drive.
The revolution joint (two blue pins and the circular groove on the green nut) allows the beige screw to rotate together the orange screw and move axially together with the green slider.
The revolution joint (two blue pins and the circular groove on the pink nut) allows the orange screw to rotate together the beige screw and move axially together with the pink slider.
The first, second and third screw-nut drives have leads of L1, L2 and L3 mm of the same hand. If the input screw rotates N revolutions, the pink slider performs a displacement of N*(L1+L2+L3) mm.
