Eliminating axial backlash in revolution joint 2
Centrifugal force causes red balls to exert force on yellow grooved washer-plates when shaft rotates, pulling it against bearing face of the blue bearing and the grey nut.
The video shows how the balls move under the influence of centrifugal force to push the plates apart and how the movement of the yellow plates helps to eliminate the shaft’s axial backlash.
This video was made based on picture 1, page 1-49 of the book:

Chào buổi sáng Thắng. Bạn đã nghĩ đến việc thực hiện một nghiên cứu về cơ chế đồ chơi chưa? Hầu hết đồ chơi đều có chip máy tính, nhưng đồ chơi cũ từ những năm 1920 chủ yếu là đồ cơ khí. Tôi không nghĩ có ai đã khám phá được cơ chế tạo ra máy tự động.
Máy tự động cơ khí trong đó có đồ chơi chủ yếu dựa trên cơ cấu cam. Người xưa đã làm từ lâu rồi. ua-cam.com/video/A-BYUpSMWCg/v-deo.html www.instructables.com/Mechanical-Cam-Toys/ ua-cam.com/video/R8l37inu__8/v-deo.html
Thank you for your idea. This is a good design to increase the travel length of rod but maintain the size of gear. But what if without chain, how can it be?
Probably like this: ua-cam.com/video/tQf6NCaMkZA/v-deo.html
Hii, what software are you using please
All videos in this channel are made in Autodesk Inventor, Dynamic Simulation.
Very good
thank you. Is it possible to send the step file? For more detailed reviews
Link to download the STEP files has been added to the video description recently.
Hello Mr. Thang, I rebuilt and modified your mechanism and used it in a project for a small punching machine at university: ua-cam.com/video/IfavLm1URtA/v-deo.html Thank you for your work!
Glad to hear that!
This ia copy of a press made in the late 70' and still being made. It is called an American Cameo or M&M Cameo. Nothing new here.
“Nothing new here.” Your comment is correct for most of the videos in this channel.
where are the inventor files of this?
Links to download CAD files of this video have been added to the video description recently.
❤❤
Thank you for this Mr. Thang! Theoretically, could this be designed where the input shaft is not internal of the osculating output? For example, could the input shaft be above the output as long as the helical slots on both shafts are linked? Or is there a simpler way of achieving that motion while maintaining constant contact?
The output tube is inside the input tube? It's possible, but the structure will be more complicated because an additional shaft must be added in the center as a runway for the pink slider.
What is the red element?
It is called pilot lever. For more see patents.google.com/patent/US2010899A/en
Thanks for another great video
Nice
You could turn most of your videos into shorts.
Thanks a lot for the reference text!
Nice concept. Can be used as a game for bodybuilder. Since lot of energy is required to rotate after loading with material whose mixture is to be performed.Joking don't take it negatively.
Really nice concept. Please provide locking & unlocking. Else it may slip and lead to accident. Since such support are used for placing heavy container(e.g. cupboard) or machines.
Nice concept. Can u create new drawing and replace that shaft having holes with gear. So that it can be locked at different positions between gear teeth with the help of dowelpin. Please don't consider it as I am underestimating u. I am Electronics engineer and not mechanical engineer.
Since 4 spring r used, force is equally distributed. I would recommend to used wavespring. Spring selection is also important factor based on mechanical design & its calculations.
Nice concept. Finally all depends on manufacturing, assembly quality. Most important u cannot place load on the yellow section, since spring loaded studs are maintaining pressure on threaded shaft with the help of yellow block.
With backlash mostly being a concern with stop-start cycles of direction changes, I'm not sure how this actually helps since it is dependent on the system being at speed to engage the mechanism. This looks more like a (strange) centrifugal clutch to me. What's a practical example/use of this as an anti-backlash coupling?
Con chào bác. Bác cho con hỏi bác sử dụng phần mềm inventor version nào để thiết kế vậy ạ? Cảm ơn bác
Inventor 2022.
This is what i looking for, ty❤
I learn so much from watching your videos. It makes me more curious and interested in study engineering. You are an inspiration. There is a place in heaven for you. You deliberately make sure that you show the viewer every detail of the mechanism in whatever video you make. I just wish that a channel like yours has more viewers. This world is full of dishonesty, obfuscation, where the things people do are only inspired by money and in pursuit of pleasure. Keep up the honest work.
Thank you for your kind comment. It encourages me a lot.
how can i calculate the right proportions measures for yellow and blue linkage? is there an equation?
Pink sliders, yellow table (connecting rod) and blue cranks create a slider-crank mechanism. So search the Internet for "slider crank mechanism calculation".
Great Sir
mr you are an einstein
my brain cant process that one
Mr. Thang, any idea on what spring can be used to withstand 200kg lid weight?
Use compression spring to bear tension ua-cam.com/video/KU4JKCrpjGw/v-deo.html and use heavy duty compression spring: www.compressionspring.com/heavy-duty-compression-springs.html
Excellent , Can I ask you some questions about mechanism? Also, I read that you were sick, I hope you are well and refreshed in God's shelter .
I am fine now. Feel free to ask questions. I will help you if I can. My email: thang010146@gmail.com
It has been done on ICON A5 aircraft but it has no hydraulic. It has been thinking for storing and was hand folded

How is such a clutch/hub called? (The orange part with the fork) is that shaft splined? Do these gears with this "special" "toothed" hub have a technical term?
Synchronous Clutch Couplings
@@thang010146 thank you so much,good teacher! All your Videos are helping me so much to find solutions for my project! Thank you again!
Can this be downloaded anywhere?
Please read the video description.
¡Gracias!
Thank you so much.

Where is most of the vertical load supported? It seems the two tracks are mostly for alignment and don't have much support against gravity, unless the sides of the wheels are sliding on the bottom? Or is the motor mount providing support?
Besides the two orange wheels with a vertical axis, there is also a small blue wheel with a horizontal axis. The latter bears the vertical load. Sorry that this small wheel is hard to spot in the video. Anyway, the wheels in this video are not sturdy enough. There are better designs, but they will make the video complicated and confusing. The main purpose of this video is to describe how to move a flush door using a motor.
@@thang010146 Thanks for the explanation. It does show the use of the motor and the path of the door well!
Gerat job , can I get it as pdf with details
Pdf file is not available. Please use STEP files instead. Their link is in the video description.
Terimakasih atas videonya, banyak video mu yg menginspirasi saya, referensi saya bertambah.
Glad to hear that.
which are the dimensions and distances? I can't import the files.
Please use STEP files of the video. Their link is in the video description.
I didn't realize how impressive this was at first. Good job
Thank you. Great project. Quick question: are the small gaps between the wall and the door necessary? Coul it be flush when closed?
The gaps can be adjusted by repositioning the green parts.
@@thang010146 thank you. I will try. Also, another question, could I proportionally increase dimensions to make a heavy duty version of this hinge? Would you recommend using bearings? I noticed that different from SOSS hinges for example you have gaps between the arms, whereas in SOSS for example they are tightly close to each other. Any special reason for that? Thank you again.
Sorry, I only made the animation of the hinge. I don't have much experience to answer your questions.
@@thang010146 great. Thank you. I adjusted some dimensions and added some bronze elements that will make the hinge stronger and work more smoothly. I do t know how to animate, so ai am not sure I didn’t cause any interference in the movements with the modifications. I can send you the new STEP file if you want to try to animate and check if movement is still good (no interference). If it is still good you will have an improved extra strong version to post.
Please let me know if there is a way I can send you the new STEP file.
Hi, where can I find the file for this project? Thanks in advance for the reply
Please read the video description.
Can anyone please tell me what this machine actually is called I mean name of machine
