I'm looking at designing something using the same mechanism used in this pepper grinder. As far as my knowledge goes, it is converting vertical Linear motion (the push button) into horizontal rotary motion (the ceramic grinder).
I would like to understand how this is achieved, especially in such a small vessel.
I'm an amateur when it comes to this stuff, and was hoping someone here could explain it to me.
I appreciate all answers.
Thanks, Beau

Hi, have you heard something about linear actuators? there are tons of ways that convert linear to rotary motion, take a look at this [video](https://www.youtube.com/watch?v=4ziGR9ggO60), if you still have questions then we are here. – Sam Farjamirad Nov 04 '18 at 22:23

Suggested a simple device called a cam, but obviously that was not liked by a downvoter... – Solar Mike Nov 15 '18 at 13:34

Linear actuators convert rotary to linear - the question is about linear to rotary. There is no electric motor here... – Jonathan R Swift Nov 05 '18 at 07:35

1The mechanism remains the same, if you push or pull the shaft you can make the rotor to rotate. – Sam Farjamirad Nov 05 '18 at 08:26

Yes and no - pushing a linear actuator will not cause a rotation because the pitch of the lead screw is too shallow. – Jonathan R Swift Nov 05 '18 at 11:54

Could you add more information to your post? As it stands now, it is either a comment or could use more explanation. – hazzey Nov 05 '18 at 13:38
