Scotch yoke of adjustable output stroke length

Input: pink crank shaft.
Output: yellow slider.
Basic Scotch yoke consists of the pink crank shaft, orange slotted slider and blue swivel runway.
A pin fixed on the orange slider moves in cross slot of the output yellow slider.
Alter the angular position of the blue swivel runway using the blue worm gear drive to get various output stroke lengths. Adjustments can be made without stopping the input crank.
The video shows the adjustment process to get from 0 to max stroke length.

It's really impressive how simple this is compared to the crank version from two years ago.

Muito obrigado e parabéns pelo seu trabalho .

This could've worked in adjusting the volume of air administered in BVM based ventilators. Amazing!!

This one makes more sense, so to speak. Are there .stl files available??

[@thang010146]

Only Inventor and STEP files of the video are available.
Their links are in the video description.

@@thang010146 Got it! I really like this mechanism because of the low part count. 🙂

Is it possible to make the simuation of the lifting of a big irregular load? Can you make a video on a lifting operation? thanks. Please share the files.

Links to download CAD files of this video have been added to the video description recently.

This is the same mechanism that is used to adjust the stroke on some machine tool shapers.

[@andypughtube]

I have never seen it used for that. All those that I have seen use a bevel drive to rotate a leadscrew to adjust the stroke. Do you have an example of one using double scotch yokes?
