Variable stroke scotch-yoke is very simple to make. Just make a channel on the rotating disk starting at the center and extending outward. Put a slider in this channel on which the scotch-yoke pin is attached. By changing the location of the pin, you can change scotch-yoke stroke from 0 to 2*r where the r is a little bit less then the disk radius R.
It is the crank and slotted lever quick return motion mechanism, one link is in complete rotation (crank) and one is oscillating about a point that is why it is called slotted lever (rocker)
Cool Izzy. Whitworth's QRM was breakthrough technology during the Industrial Revolution. To answer the slower return speed comments without getting too deep into force vectors: When the disc nears a full revolution, the arm reaches its furthest position and returns to its initial position at a quicker rate, hence its name. Throughout the cut, the arm has a constant velocity. Upon returning to its initial position after reaching its maximum horizontal displacement the arm reaches its highest velocity.
Its not Whitworth mechanism. it is CRANK AND SLOTTED LINK mechanism. That is the third inversion of slider crank chain. Whitworth mechanism is slightly different(second inversion of slider crank chain).
Hi, This motion is commonly used by Shaping Machines, not seen much in machine workshops these days. The cutting stroke is the slow segment whilst the return is the faster one. Takes me back to Technical College during my apprenticeship ## years ago.
How about in-out Horizontal motion without the quick return? Have you tried to equalize the return period to the forward motion period by internally bulging the sides (by curved bulging) of the parallel Green arm?
How about a mechanism with two rods, that oscillating in a "boxer" fashion. Would that necessitate two separate cranks? (Oris there a way to do it with one?) Can you draw that mechanism?

Hello, is there such a mechanism where another piston in a channel could be added on the other side of the disc that travels in the opposite direction as the first piston, where both pistons would oscillate up and down?
I use Adobe Flash for developing the animations. Than I use a screen video capture program to capture the animation. Most time consuming part is the Flash Development. Once you develop the animation, the rest is relatively easy.
Nice video but I think this is spotted lever type quick return mechanism .. in whitworth type mechanism two links of slotted are free here in your video one link is fixed but nice video 👍👍👍👍👍👍👍 make video perfect ..
I didn't hear any explanation of the translated pin's velocity or distance traveled in relation to the eccentric pin's radius of rotation, distance translated or it's velocity. just saw that it IS translated linearly at some rate and he fiddled with settings every few seconds. I sure hope you're not one my profs next semester. how about graphing some data at least?
I'm trying to make a shaker by changing rotationally motion into linear motion, this seems like the best way, do you know where to get parts to build one?
This one gives me a very good idea... A simple DC motor can create alternative current with a frequency rythme and an intensity of power regulation Both define as speed turn and distance from the center You need two coils on each side of the iron bar then a magnet at both sides When the magnet will go through the coil, it will generate current
And this is why I love UA-cam! Thank you so much!

very nice video for students to understand the main concept of mechanism ,much better than professor xplaining on black board

Exactly
No
Stop changing the settings while I'm trying to observe it!

Very cool presentation. Thank you very much.
Thank you for your comment and support.
Is it same as crank and slotted lever mechanism?
This is not Witworth Quick Return Mechanism. The above video shows Crank And Slotted Link Mechanism. Please correct the mistake.
You already did by your comment. Drop the name, Witworth, it is still quick return mechanism.
+mekanizmalar thank you for considering my comment
But they are actually different right..
@@Georgelajimathew505 yes obviously
What software are you using for this?
Havn't used my Router in a while, Lets give it a shot!

this one is not withworth's QRMM..please do correct it..

Can you draw that mechanism?
Great design !!!
I want to ask.. how to make different acceleration between forward & backward moving in that case??
Gracias por el video me ayudó mucho
I am happy that it helped you. Thanks for your nice comment.
It is not whitworth mechanism.
It is slotted bar quick return mechanism

Well said,
anyway SUBSCRIBE my channel MDhaiderYT 👍😊
E 'un piacere, grazie per il vostro continuo supporto.
Please tell me software you are using.
I am using Adobe Flash.
On which software animation is made
I use to use Adobe Flash and Steve Jobs killed Adobe Flash.

Thanks your visit and nice comment.

You are welcome.
+ mekanizmalar - Yeah!!! I can move forward and backward an arm with this!!! Thanks a lot, it's a helpful idea.
Thank you for your comment and support.
@@mekanizmalar change it's name
Which program did you use?
Thank you in advice.
Adobe Flash and AS3
I am going to build this for one of my projects. However I will use n52 magnets for no contact use through glass.
Sounds interesting. Hv u made it yet?
Another shaper?
Yes. It is.
Which simulation software u used
Adobe Flash
nice video
Buen diseño, montaré este modelo en un sistema de balancín para una exposición.
Gracias.

Thank u so much. Will you give me the download link for Adobe flash
nice Im gonna use this
I thought I can simulate the motion myself in the website provided, but I cant. It just pictures in there.
if thats because of the Flash, then no way. I am annoyed, cant test it out myself.
I am sorry about that, but browsers no more supports Adobe Flash.

it is called the program used to design the mechanism
can someone give me a matlab code for this mechanism please
This is crank slotted quick return mechanism
vorrei sapere dove comprare il meccanismo . Grazie
I am sorry, I am an animator not a seller.
This is Slotted link quick return mechanism

super vidos to study
This one is not whitworth quick return mechanism. It's a crank & slotted quick return mechanism. Don't teach wrong to students
Well fuck, leave the damn setting alone long enough for us to observe the fuckin’ thing.
