Whitworth Quick Return Mechanism
HTML-код
- Опубликовано: 26 авг 2024
- This is simpler version of Whitworth Quick return mechanism. These mechanism are used where reciprocation motion in return stroke is much faster than the forward stroke. A machine shop shaper tool is a good application for this mechanism. Forward and back stroke lengths can be changed from zero to predetermined maximum length by changing the location of adjustment pin as shown in the video.
And this is why I love RUclips! Thank you so much!
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.
Thank you for your visit and explanation.
Stop changing the settings while I'm trying to observe it!
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.
Thank You for this comment!

very nice video for students to understand the main concept of mechanism ,much better than professor xplaining on black board
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).
Exactly
No
this one is not withworth's QRMM..please do correct it..
E 'un piacere, grazie per il vostro continuo supporto.
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
Havn't used my Router in a while, Lets give it a shot!
What software are you using for this?
Very cool presentation. Thank you very much.
Thank you for your comment and support.
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?
It is not whitworth mechanism.
It is slotted bar quick return mechanism
+Amarjit Singh cheers :]

🔴 What Is Islam? ⚠️
🔴 Islam is not just another religion.
🔵 It is the same message preached by Moses, Jesus and Abraham.
🔴 Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God.
🔵 It reminds us that since God created us, no one should be worshipped except God alone.
🔴 It also teaches that God is nothing like a human being or like anything that we can imagine.
🌍 The concept of God is summarized in the Quran as:
📖 { “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4)[4] 📚
🔴 Becoming a Muslim is not turning your back to Jesus.
🔵 Rather it’s going back to the original teachings of Jesus and obeying him.
Well said,
anyway SUBSCRIBE my channel MDhaiderYT 👍😊
Is it same as crank and slotted lever mechanism?
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
This is crank slotted quick return mechanism
This is Slotted link quick return mechanism
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?
it is called the program used to design the mechanism
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?
What software was you used...??
Buen diseño, montaré este modelo en un sistema de balancín para una exposición.
Gracias.
Gracias por el video me ayudó mucho
I am happy that it helped you. Thanks for your nice comment.
Great design !!!
I want to ask.. how to make different acceleration between forward & backward moving in that case??
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 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.
as
Which program did you use?
Thank you in advice.
Adobe Flash and AS3
+ 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
Thank you!
You are welcome.
This is crank and slotted lever mechanism brother please check.
On which software animation is made
I use to use Adobe Flash and Steve Jobs killed Adobe Flash.
Its crank and slotted lever quick return mechanism not whitworth quick return mechanism.
nice Im gonna use this
can someone give me a matlab code for this mechanism please
Please tell me software you are using.
I am using Adobe Flash.
Will you please explain how to creating video like this?
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.
Thank u so much. Will you give me the download link for Adobe flash
nice video
Nice video 👍
Thanks your visit and nice comment.
grazie ancora
Which simulation software u used
Adobe Flash
vorrei sapere dove comprare il meccanismo . Grazie
I am sorry, I am an animator not a seller.
scotch yoke with adjustable stroke -any idea please reply
and for above how u fix pin location
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?
Thank you for your comment. I do not know where to get parts and manufacture it. If you know a machine shop you may ask them for the best advice.
F*ck and I thought I was being original when I came up with this for my project
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?
It is crank and slot lever Mechanism please change the name
Another shaper?
Yes. It is.
nice discussed
Thanks.
For car windshield Wipers
love it- Kinematics here I come (again)
This is not whitworth quick return motion mechanism
This is crank and slotted lever QRM
Thanks for your correction.
which is this software
Adobe Flash
Adobe Flash
good
Thanks.
super !
THIS IS CRANK AND SLOTTED LEVER
yup that quit intersting
super vidos to study
I like 🔧
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.
👍👍👍👍👍🙋✌️
Thank you again.
😁👍➡️💡
super dme 083
It is not whit worth buddy
Dude..... this is NOT a Whitworth Quick Return Mechanism...... 🤷🤷🤷
Yes, I know that.
wrong mechanism
good
