Please Let Me Know How Much You Like This (1 is very Bad - 10 is Excellent)




Screw mechanism 3




The mechanism consists of 2 movable links, 2 screw joints and 1 prismatic joint.

In 1 rev of the blue crank:

The nut’s displacement s = (h1-h2).

h1: pitch of the screw joint of the blue screw and the base.

h2: pitch of the screw joint of the blue screw and the green nut.

h1, h2 carry negative sign in case of left-handed thread and vice-versa. For this case, h1 = -2 and h2 = 3 so s = -5.

Wanted s values can be obtained by combination of appropriate h1, h2 and the thread direction.
