How A Ball Screw Works (Animated)
This animation shows how a recirculating ball screw works. It is important to note that this has a external return tube and there are other designs and pathways, but they functionally all work the same. Not shown are the scrubbers which close in the mechanism on either end and which prevent debris from fouling the mechanism.
This was designed and animated in SolidWorks 2020. In total there are 70 bearing balls in this animation with each having its own path mate and path mate motor. (I would love if someday SolidWorks added 3D chains)
This animation was originally intended to be longer with it going back and forth a few times, but SolidWorks put up a good fight. Hopefully you still get the idea.

How A Drill Chuck Works (Animated)
Переглядів 28 тис.3 роки тому
I made this animation to show how a 3 jaw drill chuck works. Commonly known as a Jacobs Chuck. This was modeled off a $20 WARRIOR 12v Lithium-Ion 3/8" Cordless Drill/Driver from Harbor Freight but in principle all drill chucks work about the same. Animated in SolidWorks 2020. (the front outer grip should be rotating, but I could not get it to be sliced in half and rotating at the same time due ...
How a Trochoid Pump is Drawn. (Gerotor Pump)
Переглядів 7 тис.6 років тому
Trochoid pumps (AKA gerotor pumps or cycloids) have some fascinating geometry and they are surprisingly easy to draw. (This was animated in SolidWorks 2017. SolidWorks does not currently allow you to live trace in animations. This was created/filmed using the built in screen recorder and hitting the calculate button. It is a frustrating workaround as you can not hide the motor arrows and the qu...
Trochoid Pump Animation (Gerotor Pump)
Переглядів 31 тис.6 років тому
Inspired by AvE's video on Trochoid Pumps I tried to draw and animate one. Turns out drawing a Trochoid in SolidWorks is harder than expected.... The liquid would be pulled in from the expanding green region and pushed out in the shrinking red region. I made an animation on how to draw a Trochoid pump which can be found here ua-cam.com/video/jQo2hkxQHRY/v-deo.html AvE's video ua-cam.com/video/O...

What happens when I get bored studying for finals. I probably have about 7 hours into it but most of that time was spent learning how to animate and experimenting with motion so I don't consider it time wasted.
Great video! It would be very helpful if you would provide dimensions for the circles
The dimensions are not really important so much as the ratios. You start with the 1st reference circle select the number of lobes (in this case 4). Each red and blue combo will cover 1/4 of that reference circle. You can actually vary the ratio of the red and blue rollers however you like so long as the circumference of red + circumference of blue = 1/4 the circumference of the 1st reference circle. In this case you have 4 lobes on the 1st reference circle. The second reference circle is always n+1. So in this case 5 lobes. So the second reference circle has a circumference = 5/4 * circumference of the 1st reference circle. Use the same red and blue rollers on the second reference circle and boom you are done. IDK I am a very visual geometry guy, there a super fancy equations to draw it but that is not my style
Just curious, What are common failure points on these ball screws and how would you prevent them?
I don't work in operations so I am no expert on how they fail, but the few I have heard about is they are a wear item so the groves and the nut can wear out which creates play (guaranteed to happen with enough use), the rod can be bent, the grease/lube can expire and dust can foul the mech.
I was looking for this video
I tried to figure this out on my own and was not even close. The guy who invented this was a genius
They sure were
@jttv2000 Any way to get in contact with you besides here? Would like to pick your brain on a couple items you've posted, and a youtube comment section isn't exactly the best method of communication.
😮
can i get to cad model pleasen for college project
Nice explanation
hey. any chance for 3d models?😊
Myr
😎 VERY 😎 COOL 😎😎😎
Very nice 👍
Hi, could i get your email address regarding some request? Thank your
Excellent animation cleared my concept
What program do you use to make these animations?
That all solidworks. Probably not the easiest program to do it in. And why the arrows are kinda glitched
Great Animation! Thanks for this video✌🏽🔥
But I think the direction of the nut in animation is wrong. Balls are going left, then nut should go left as well. What do you think?
Nope its correct. Tho this old animation has the helix opposite most screws so you can see it more clearly. The bearing balls contact with the threaded rod and the nut moves the balls through the helix "backwards" then they leapfrog to the front via the return tube. My more recent animation has the helix in the traditional orientation ua-cam.com/video/oEPrXljqeHA/v-deo.html
@@jttv2000 but balls go left by pulling the nut left, why nut should go right?
Hey @jttv2000 Taht is so awesome animation. Can I use a piece of it for one of my videos? I will reference your channel. I am also willing to compensate you for the use of the video.
Go for it
@@jttv2000 Thank you a lot!!
Hello Dear Friend, we are original ball screw factory, can we have chance to cooperate? Thanks.
So basically each ball bearing "pushes" the nut from the screw shaft as they travel around a path, thus moving the screw in linear motion
But I think the direction of the nut in animation is wrong. Balls are going left, then nut should go left as well. What do you think?
20m video averted thank you!
Glad it helped!
Thanks this is great!
Thanks for watching
could you share us the 3D model pls ?
Isko water pump banaa sakte hain kya
Cool
please give link of this 3D model (files) in the description.
If you have the nut in the opposite direction and rotate the screw will the nut go in the opposite direction?
Do you have a detailed video on how to draw it on solidworks?
Hi, I need a very short clip of a ball screw animation for a video I am about to release. Would you be happy for me to use 4-5 seconds of one of your animations? I will of course reference your channel and link back to it
Go for it.
@@jttv2000 appreciated. Thank you
good video, the motion hurts my eyes 😵💫
Great animation and clearly explained how those things work!
Yeah what he said
fantastic work
Thatnk
i don't think my printer can make this
Excelente trabajo.
Muchas gracias
I have made a updated version you can check out here. ua-cam.com/video/oEPrXljqeHA/v-deo.html
really awesome work (can we use path pattern in bearing to do the animation ?)
Chain mates don't allow you to select a 3d sketch and none of the other patterns would help as they don't add useful mates. And you cant even copy and paste a ball with a path as that is a "advanced mate" even though you just select a point and a line. So the only way i have found to do it is add 70 individual path mates with a precise starting location. Then do 70 individual path mate motors. It sucks and it really puts a strain on the computer, but to be honest SolidWorks was never made to do this.
Awesome animation, thanks!
Wow - cool!!!
How are you ref happy day We are ultra precision company BAEK YEON thanks

Is this like ball bearings to reduce friction?
Yep.
watch until the end for a sprise
why center lead screw is bend
Why not ?
Hi & Thanks for reply! No, the one I was talking about looks like the picture you have but has 6 tooth inner rotor .it may just be the same with another name.
I agree with others, a short tutorial would demonstrate implementation of a lot of good mates and animations considerations. Good video! I liked your 3D print of this, too.
You could look up some more thorough animations yourself if you’re still interested. There’s tons of tutorials out there, and services like Brilliant, Masterclass, Skillshare, The Great Courses, etc. which you can use to easily teach yourself through. Each site has its own free trial program, so you can find what you want to know for free.
Cool print!
I been trying to find out,are these pumps the same as a Gerotor pump?
That is one name they go by.
Could you make a tutorial video
