Even if it broke, since he isn't using a machine, but his hands. The amount of force will not lead to enough force to make it penetrate his eyelid and into his eye. Not to mention, he looked away, which reduces the risk a little. The highest risk he has, is a piece getting into his Ear hole.
Hey Angus, really nice design and idea, there is only one thing that makes it a bit tricky. The only reason the clutch works is because the inner frame and the outer frame slide along each other when rolling in the right direction. The balls/cylinder/cones now ONLY function as a blockade when rolling the wrong way, but not as a rolling element in the right way. I think the spring exists within the original design for that reason. Your design works, but i'd like to see a version in which there are rollers functional in both directions or at least a mention and consideration. Thanks Angus for great content!
Great idea. I actually left you a note on the one-way mechanism under it's video before I've seen this video. Now you found I think a better solution than the one I suggested I guess.
I just purchased an ender 3 and have never done anything 3D print related. I’ve been binge watching your vids. Your a smart dude! Great videos! Very helpful. I’ve yet to print anything yet. Still learning what the heck to do. Haha
"I'm not an engineer" No, but how you took this project and applied it to a previous one with the intention of improving it most certainly is a good practice of engineering if I've ever seen one.
Love the bearing mechanism. Well done 👍, I’ll download the file and print it myself. As for the T-shirt... it’s very original, I love it and will get myself one next month.
One-way bearings are used in the main gearbox assembly on Airbus helicopters. It is what allows the rotor and rotor shaft to freewheel when the aircraft loses engine power and has to autorotate. It also keeps the sudden stopping of the engine from damaging the main gearbox.
Not really, you'd have to push faster and faster so that the acceleration imparted on the rollers are greater than their current rpm does, cause if not, it'll just "slip" because technically, the rollers are still rolling forward, only slower as you push. This will work at low speeds, but you might as well just walk and save the awkwardness
A company called Onyx actually makes sprag clutch hubs for mountain bike wheels! It's totally a worthwhile application for these mechanisms. They have the advantage of near-instantaneous engagement, and they're silent
Make it out of wood and throw it on William Osmunds wooden, lazercut bike! /s Looks awesome, I'm surprised by how well it works and seems to handle torque.
This is very slick! I had a little flash of an idea to combine this with a thing I've been working on here and there - a sort of gatling gun style prop. Using a power drill or screwdriver to drive the whole thing, the printed barrel set kind of stops on a dime when the trigger is released, just because it doesn't weigh very much. I think using a roller clutch like this could give it some extra spindown time when the motor just stops, but still catch it firmly enough to spin up instantly when power is back on.
You said you are not an engineer but you are certainly finding solutions like a very good one. Trial and error is the mother-process of engineering (before and many times still now). :-) Congrats and stay the route!
Have you tried to reverse the taper. It might improve the performance. I say something about this on one of the math channels. It has got to do with the stability of the system and the inherent instability of the shape you have used for the bearings
If this one way clutch is not attached to your wheel hub but to the pedals, and you shift to a lower gear then you can put less stress onto your pedals (and one-way-clutch-thingy) while still delivering enough torque to get rolling. Do this sort of stuff to make it work, bake it in an oven, print 100% infill, etc... I know one thing: it will work if you do all of this and if you ride carefully, but i'm not sure how long it will hold up, and that's the interesting part.
Gravity is only pulling a couple rollers into binding... that means that your device is only acting at about 15-20 % of its capacity. A good safety margin against catastrophic failure, but it also undermines just how good your design could be. Great jon
this is super cool, of course, if you want to make it more secure and avoid it from skipping to easily you can always add more internal arms and rollers. you've probably already thought about this but just a thing I thought id say.
The reason why sometimes it's getting stuck or stuttering whatever you call it, is due to the fact that this design works perfectly only in horizontal position, once you put it vertically and stop it, observe carefully. Some of the bearings are in "stop/block" position due to gravity. Ofc this doesnt really apply once you reach certain RPM but it is the main reason why there are springs in original design.
The balls arent functioning as the bearing in this situation, the balls are the locking mechanism. The outer ring is only held in place with the solid inner parts which would cause friction. It would be like if you made a car where the wheels lock against the ground in reverse but raise up going forward so that the car can only slide on the undercarriage one way but not the other. Not the original function or more efficient or even very useful.
Daniel McArthur yeah, I was hoping he wasn’t going to go the whole video calling this clutch a bearing. That would have been tough to sit through lmao. At least he admitted that he’s calling it the wrong thing.
My guess for why the rollers slip is because as they get wedged against the sides they are pinched harder and harder until they overcome friction - likely on the straight inner part, because the outer part may add a bit of spin as it breaks loose, both rolling up the outer part, sliding against the straight inner edge, and springing out of the wedge. Changing the design of the inner edge from straight to curved might help with this. Additionally, not all of the rollers are getting wedged, and may be reducing the force needed for the rollers to spring back out. If you could design the one way bearing in such a way that all of the rollers are all held at approximately equal angles apart, this would almost guarantee that all of the rollers would be wedged between the inner and outer edges; and the plastic may stretch and compress a bit, if only slightly, as well.
You, my good man, have earned yourself a new subscriber! It is amazing to see your inventions in motion. Also, yeah, the first thing that I thought when I read the Video Title, and would definitely love to see is, this mechanism on a bike. (:
You can enhance that thing by printing a material spring into to construction or a spring that you can insert after printing. If you turn the clutch backwards not all rollers block. So that's what the springs are for. Either find a way to 3d print them or insert them with a hole or a channel or something.
I was thinking something similar, but concluding instead that he could probably use his original design again with the tolerances appropriately scaled up by a factor different from the rest of the model. It's possible his hourglass-shaped rollers are a better design anyway, though.
So funny.. chatgpt and I were talking about this earlier today learning the differences in these one way clutches. Maybe a little late to the party but here I am
I'm an aircraft mechanic student, and this roller clutch design is actually commonly used in helicopters. Often referred to as a "freewheeling unit" and allows the main rotor to rotate freely if the engine RPM is lower than the RPM of the driveshaft driving the main rotor.
A 'one way ball bearing' was called a "sprag clutch" a bazillion years go. I was instructed on them with the Army 2 1/2 Ton and 5 Ton cargo trucks in 1970. The sprag rollers were used to engage the front axles 'automatically' when the rear wheels are spinning. To disengage, the vehicle needed to be backed up a very short distance to have the front wheels rotate freely again.
