Screw 3-stage telescopic actuator
HTML-код
- Опубликовано: 8 сен 2021
- Input: yellow screw.
Green slider has the green nut that together with the input screw create the first screw-nut drive.
Pink slider of inner thread and the orange screw create the second screw-nut drive.
Jade slider of inner thread and the beige screw create the third screw-nut drive.
The revolution joint (two blue pins and the circular groove on the green nut) allows the beige screw to rotate together the orange screw and move axially together with the green slider.
The revolution joint (two blue pins and the circular groove on the pink nut) allows the orange screw to rotate together the beige screw and move axially together with the pink slider.
The first, second and third screw-nut drives have leads of L1, L2 and L3 mm of the same hand. If the input screw rotates N revolutions, the pink slider performs a displacement of N*(L1+L2+L3) mm.

This has many applications in robotics ! Many many thanks for sharing your designs to the general population free of charge. This is charity of the highest order.
I like the design it's fantastic, however It would require a lot of grease I guess? otherwise it would wear out quite fast. I wonder what materials the screws are from? a very hard metal, together with some way of ensuring grease stays on for 20,000 cycles of rotations? Also the complexity of the parts is fairly high, and so the price of machine the parts... because they seem difficult to cut?
You are incredible... I agree with one of the comments... This is charity for many...your designs compel to think something new...
Fantastic work Mr. Thang!
Con luôn dõi theo các video tải lên của bác. Thật tuyệt vời, con cảm ơn bác
This is genius level work!
Great work Mr Thang
machining this will be pain in the ass
351 thousand subscribers isn’t enough. You need 351 million subscribers. This is not fair.
Thank you for your encouraging comment.
Great idea, sir!
Wow! I just brought one a week ago and dissected it to make sure how it works!
I made this animation just based on my imagination of how the actuator should work.
I will be very grateful if you tell me the working principle of your actuator.
Where did you buy it? Can you upload a video?
Incredible!
Very good man.
Very good work
Splined threads... Now there's something I haven't seen in a loooong time.
Splined threads can act like taps, gotta be careful in instances like this!
amazing stuff, thank you for sharing
Glad you enjoyed it!
Little hard for me to understand how it can rotate out evenly.
Took a while to find out, the revolution is blocked to rotate at the same time, so each step is threading out by the same ratio. And the thread base is separate by each step, so depend on each base, each of the step comes out evenly then.
Nice complex!
This is a hybrid of a screw and cam mechanism. Except for the outermost screw, all the screws have grooves cut through the thread axially and the next screw in series has a follower to slide along that groove. This forces them to turn in unison while allowing axial motion. The mechanism expands because the casings have a similar cam design, but are held stationary radially, creating an axial force due to their female threading. Because each screw has a casing that it's paired with and locked together axially with a retaining ring, the screws are pulled outward by the casings as they are in turn pushed by the screw threads. As long as the thread pitch is the same regardless of the thread diameter, the screws will move evenly.
Pretty ingenious!!! For those who may not realise, the word engineer has nothing to do with engines. It was derived from the French ingenieur which means genius in English, or at least that's what I was taught when I was a young engineering student.
Brilliant!
Hello master, how are you?
I'm printing these pieces with 7 sizes to have a greater reach. I have a question should I print all the pieces in half and then glue the two sides together or can I print with one size and just fit them all together?
Wonderful work !
I’ve a challenged for you
Would you be able to do a mechanism like
This one but!
When the three different module have reach their full extension
The pink one or the blue one start to roll in order to be the screw of a scissor jack to act like an anchor dowel
Please explain your request using sketches.

perfect!!!!
Interesting idea, but looks very difficult to machine. Ease of manufacturing is important when conceiving a mechanism.
Good
Thank you for the awesome work. What is the thread on them to push them out at the same time. Is it 1 to 1 thread size.?
Like M10 bolt and nuts size or do they change from M6 to M8 to M10 etc.
All the thread leads in this animation are of the same value: 2 mm.

👏👏👏
Would you do any designs for a 4 stage as well? Would love to see how this could be applied for 4 or more stages.
For more stages just add more the beige and blue parts.
I would not make the animation because it will take a lot of time and the video will look tangled.
@@thang010146Mr. teacher i are doing for 7 stages and after can print. after that printer i show for all. thank you
@@Fillkids Hello FiliKids, did you manage to build a 7 stage prototype?
@@emotiveworks7624 yes i did, not single. kkk but ir good.
This is amazing, now how can it be modified to have a reciprocating and fast action ?
This can be a compact high amplitude vibration generator.
Use multi-start thread of large lead.

Dear Master，thank you of your effort. May i ask wht software u use or which free do u suggest me as a good start and print out 3d. Many thanks.

All videos in this channel are made in Autodesk Inventor, Dynamic Simulation.
The CAD files of this design are not ready for 3D printing. Some modifications are needed.
If it was put into a lightsaber design it would look wizard.😁
Dear,
I am a professor of Technical Mechanical Drawing and a follower of your channel. I would like to know if it is possible to make the drawings available to be used in my classes. Thanks.
He retirement in 2002, i dont think he have problem if his product used in education, you can contacts with him via emails, just check introduction of his channel
Please use the video's CAD files to create the drawings.

@@thang010146 Thanks! All material is welcome for Education.
Can we Extend this system to 60 feet hight for the telescopic Mast, and can you please suggest which pipes will be feasible along with material s this project,
It is not suitable for a high telescopic mast.
Use cable mechanisms:

Is it possible to use this kind of actuator in humanoid robot arm? I'm not an engineer, but I'm trying to model a semi-realistic steampunk robot, so I need to know about actuators that could possibly be used in this kind of machines
This actuator is difficult to produce and has not yet been commercialized.
Use actuators available on the market:

Hello master, this is the project I talked about earlier. I'm redesigning the same now with 7 pieces. the base is 18cm and it reaches 81cm when fully open. I have a doubt. The conversion of mechanical force and what makes the spindle hurt and push the next parts and so the great magic happens? Can I forward you an email? Thanks

Pkease let know What CAD/Animation package is used for this?
All videos in this channel are made in Autodesk Inventor, Dynamic Simulation.
Too bad this isn’t on the market.
how does the mechanism stop without the pieces untying at the end of the expansion?
I don't understand your question.
It stops when the input screw (yellow) stops.
@@thang010146 I mean that if the input screw keeps rotating then it will let go of the system and unscrew completely off or is there a blocking mechanism that prevents the input screw of unscrewing completely
interesting
is it possible to go on and make a Screw 4-stage telescopic actuator, or even more?
I can't. Too complicated.
@@thang010146 are there other ways to make a telescopic actuator which extends by rotation?
Downloaded Autodesk inventor file, Can you help me to learn how to animate the downloaded file. Thanks
Click Environments, Dynamic simulation.
