I believe you are a natural born teacher. You are able to convey complex concepts in very simple language for those of us who want to learn to make our DIY projects better and more functional.
Brilliantly demonstrated! Reminds me why I took physics in college (not engineering but just enough). Starting with W = F*D and Power algebra, with a demonstration with you kids moving bricks & a seesaw was the perfect finishing touch that made this video unique!
I love watching your channel. You are such a great person and I would love to have had a shop teacher like you. Keep up with all the good work that you do.
I am now able to UNDERSTAND the why's of certain design choices that I have previously only understood by "rule of thumb" before . This was EXCELLENT !
As an ME, there are A LOT of calculations that can be made when designing and selecting gears and we went over many of them in my machine design course in college. However, what got overlooked in the class was the basics that Jeremy goes over here. Well done sir
JF, i came to you as a lost puppy, now 2 or 3 years later, I AM THE MOSTEST MASTEREST ELEKTRUCIAN EVER!!! Okay, maybe I overstated that a but but it was because of your kind words through PM and inspirational videos that, from brain picking of my most learned ac techs and electrician friends, I suddenly have been tasked with some high profile single to 3 phase conversion solutions and being called on some CRAZY induction motor repair and implementations of VFD static conversion, efficency increases through complex capicitor math and I have learned far more than I ever thought possible! ALL HAIL THE GREAT JF! Thank you!
Sir I am 22 years old. You, stuff made here, destin sandlin, mark rober have been a great inspiration for me to learn science and engineering. Thanks for these tutorials. I do not have any degree in engineering. I have zero tools with me. But I aspire to learn how to use tools and learn to design, test and make stuff like you all, from an idea to a real thing. ❤😊
I am a retired engineer, 76. I am so excited to hear of your interest in engineering! You have more tools and information available today, than in the history of humankind. For example, when I started with micro controllers, the minimum cost of entry was about $50,000 US. That's in 1980's dollars!! You are in for a wild and fun ride :)
There's an awesome presentation from an nvidia fellow that happened at the recent gtc. It's about using agnostic data models using videos of things in motion to train a general control model for adaptive robotic movement. The mechanical side is way farther ahead than the software governing the motion for whatever task the robot may be put to use for. Like bipedal robots and a general kinematic model where the software will be aware of the most most natural movement for the dof, sensors, and such inherently without direct human intervention. Note that I do not call this ai. Llm and large data models have yet to earn the name that everyone associates with artificial intelligence. Large data models use simple mathematics backed by compute power to basically play a fast game of connect the dots for whatever task the models are built for. Agi is very, very far away. Kinda like how rasterization it's a cheaters way of making graphics look pleasant in real time. Ray tracing in games looks cool but it's a bolted on technology crippled by lack of real-time compute power and real power draw. 2 light bounces for an aggregated group of similar triangles is far from what can be done in offline rendering where it takes hours for super computers to render a single frame of woody's head (in toy story 3 for example) in a closeup with the bokeh effect around him. Ts3 was the first cg movie to use light as the governing principal for how everything looks which is why I chose it.
Holy heck, as a former EE & CS major who secretly wished he knew more about mech E, this title is the intro I’ve always wanted to see. I’m crazy excited for this.
I am an apprentice machinist at a machining company. While doing maintenance on a large surface grinder today, I noticed tears in a belt attached to a motor and was shocked at how forgiving the whole structure had been in that state... I admire your passion and understanding of engineering. The power of the maker.
Thank you for explaining this and many other similar topics, you take the time to make your videos simple, engaging and informative. I've learnt so much from you and you have such a decent personality, the world needs more people like you 💪
As expected, another mechanical engineering masterpiece! Thanks for featuring our hypoid gear at 24:51 Happy to help whenever you need anything, let us know!🛠
I forgot how awesome your channel is, Jeremy. I remember the first video I watched where you had a little rotary tool contraption in your tiny shed. You are a top 5 UA-cam engineer in my book. Up there with Mathias Wendel and TPAI. You are an inspiration to us lazy dads who probably spend too much time watching and not following along. You rock!!
To Mr Fielding, I’m a fitter and turner, also electrician. 8 years of apprenticeships, also done 6 years of university. Your videos are great. Just saying g’day and really appreciate the effort you put in to making these
I feel like I’ve been waiting my whole life for a video like this. I’ve tried researching gears and how they work, to have a better understanding. But nothing has compared to this, thanks Jeremy
Gears and levers are like magic. I was digging fencepost holes recently and had to try and get through some very dense material. After first attempting to apply greater force to marginal improvement, I realized I should instead use leverage instead. Simply shoving the spike in and then using the length of the metal pole (8' long or so) I was able to greatly improve my effort to output (work) ratio :)
Thank you for your explanations being so clear and covering the basics. I have worked with motors, engines and gears for over 40 years. You have explained things in a way that even what I already knew, I now UNDERSTAND better.
One of your earlier videos was on where to get free motors. There's room for a similar video on gears and gearboxes, etc. If you do that, though, could you invest a few minutes of video on things to look out for for safety and efficiency--how to spot a bad gear or when a chipped tooth is still good enough, etc.? Thanks for what you share!
This is a superb video; huge thanks for putting it together. One thing that is worth mentioning is that virtually every manufacturer of power transmission components provides extensive resources to help designers select components. In other words, you as a designer have access to a lot of information to ensure that you’re doing the job properly.
I am now able to UNDERSTAND the why's of certain design choices that I have previously only understood by "rule of thumb" before . This was EXCELLENT !
never thought gears could be so interesting, the gears in your logo make a lot more sense now that I see how integral they've been to all your projects, thanks for making this!
Very well presented Jeremy! I'm a mechanical engineer with 45 years of experience. In my many years I have not met many engineers as articulate as yourself. Sadly, many brilliant engineers lack good communication or social skills. 👍👍👍
I’m gonna go through your collection/ library of videos, organize them into a curriculum, and study, test myself off each video until I can (hopefully) grasp everything you’ve taught. As a carpenter in Orlando for Disney and universal we incorporate much much more than wood. Thanks Jeremy! 😎
I made a pendulum clock, but I cut the gears by hand on a band saw. Clock works great. Also my '65 Chevy Corvair has the 90 degree bend in the fan belt. Works fine if you have the correct tension, it needs to be kind of loose when the engine is cold. Alway enjoy the engineering stuff.
My first two clocks were cut by hand as well. Check my older UA-cam videos! I said two clocks in the video but there were actually three. And all three have videos.
You can also add a position sensor to the output of your device to sense its true position to help account for some of the effects of backlash. Different set of tradeoffs, of course, but it's another option.
Hey Jeremy! Thank you so much! As a non-engineering background hobbyist, some of the existing resources already out there have been difficult to understand so I sincerely appreciate the simpler language you’ve used to explain gears. If you ever consider making a follow-up to this video, could I ask you to cover linear to rotational transducers and vice-versa covering the various tradeoffs you make and what you gain from using each? Things like the rack-and-pinion, scotch yoke, crankshaft and other types that aren’t necessarily gears, such as a cable spool (I also remember one that was this star shaped thing with four circular grooves to convert a slow rotation into back-and-forth linear. Basically an improvement on the idea of a scotch yoke)
Love Your channel Jeremy I think it's great that you get your kids involved but , more importantly, they seem to enjoy it as well and have fun . Keep up the Great Work Sir .
I have always loved gears! I have had so many RC cars throughout the years, go karts, mini bikes, dirt bikes, quads so I learned a lot about ratios at a young age. So I go into machines about ten years ago and bought my first south bend lathe that was missing 12 or 13 gears or something like that. I bought a Bridgeport a short time after that then found out I can make gears at home just by buying a $320 indexer from Amazon and the cutters for another 125 so I did it. I actually made a full set of gears. Wait I’m sorry, I made my first gears on my drill press lol. They came out perfect!! I have since sold that lathe and bought a 1980’s Clausing in bran new condition almost. It has absolutely no wear at all. Anyway gears are awesome and so are the machines that make them. I love it? Lmk if you ever need any spur gears made
I think I posted quick videos clips of it. I’ve done so many projects I was gonna start a UA-cam but I just never followed through. I don’t think I’d be a good talker
To get better efficiency out of your kid powered brick mover, I'd say a water gun or hose would speed up things and the operator wouldn't have to actually chase the work...so to speak. Honestly that is the best explanation of " horsepower?" Ever.
Great introduction! I'm excited for this series :D Thank you as always for breaking things down and bringing your professional expertise to the maker community!
Nice summary of the different types of gears. 50 plus years in automotive I've run into all but one gear you mention here; that is the strain wave gear. There is an e-bike I'm interested in buying that uses the strain wave system.
So your the Gear guy of youtube ❤❤❤❤❤❤❤ also your robots are awesome can't wait till chat can use them independently and we can watch it make whatever it makes 😊 and you seem like a really good dad bro and that's the right stuff right there ❤
Very good video! One thing you might include around 19:30 with the downsides of the helical gear is that it also increases the amount of heat generated, which will also rob some of the power from the system. While it's a minor thing, it's still important, and you're always on top of stuff. I thought I was subscribed prior to this, but when I clicked on your video I noticed I wasn't, but I corrected that and now I am!
Hi, Jeremy! Unless my understanding is flawed, I think that you meant to say that the diametral pitch must match for gears to mesh. If the pitch diameter is the same, you're stuck with a 1:1 gear ratio. I'm grateful for your explanation of strain wave drives in another video. Just a few years ago, these were a dark art, and almost impossible to find information on.
I ALWAYS enjoy your videos, Jeremy. They are supremely educational and informative, but also educational, especially when you include the 2 legged props that require food and clothing to work...
If you can't explain it simply, you don't understand it well enough” Albert Einstein. You've explained the lever concept so simplistically I've never heard it explained so simply And completely you're an excellent teacher.
as a beginner i try to learn all this information piece by piece from different sources and it's confusing. thanks for the playlists. much appreciated !
Took the motor out of a broken vaccuum, tried to turn it on without holding it down with anything... spun so fast and hit the floor. lol, i think they use one of these with some type of gear reduction to open and close a garage door. motor that spins at like 5000rpm to spin a garage door open at medium speed. super cool
@Jeremy Fielding this is the second video I watch from you and I'm already a subscriber, just wanted to say thank you for making such interesting content and at the same time entertaining and enjoyable, gonna check what else you have in your videos, thanks again!
This is a really useful overview, thank you. It invites many re-watches. With my optics background, I tend to overlook the mechanical side of daily technology. It's fascinating.
This is better Jeremy... not many of has can afford or even have need for a robot or CnC Machine... More shows on the meat of mechanics is much more interesting to us wannabe engineers. I learned a lot from this one and the ones you did on motors was also interesting.
Something to note about bevel gears and hypoid gears is that they are slightly different for two reasons: 1) the tooth profile, which you mentioned, but also 2) their shafts are perpendicular but do not intersect. If you want perpendicular, intersecting shaft axises but better transmission than straight tooth bevel gears, you start looking at spiral bevel gears. These tend to be pricier as well since they are harder to make. Additionally, unless I am wrong, a hypoid gearset doesn't necessarily have to have perpendicular shafts. They can be designed so that the input is at some specified angle other than 90deg. I know this gear type exists but I am not sure if they have a special name or not.
21:30 Another strategy I've used to avoid backlash in positioning is to change where you measure the movement. If you put the movement sensor on the final output, even if theres backlash the movement wont be registered until the actual output moves. I've used this on a satellite dish positioning system to allow the drive gears to slip in case it crashes into itself. I can still tell the actual position by measuring the movement of the mast instead of the motor's movement, even though the motor is spinning away and slipping.
I believe you are a natural born teacher. You are able to convey complex concepts in very simple language for those of us who want to learn to make our DIY projects better and more functional.
Yes, great job Professor Jeremy.

Great lecture on gears. Can't wait for part 2!
Love the " nerdy" details. Thanks for all your details....
You had me at the Kid Work analogy! Also, another exceptional lesson! Thank you! I knew I saved those motors for something!!
Thank you very much Jeremy. I love your videos. They teach us a lot. Keep sharing please. Best luck!
So you're saying if I have a small shaft I'd be better served using more speed and less torque? Asking for a friend.
Faster rotation might help
But remember it doesn't change the amount of work being done.
Dude literally just said he has a small shaft! It's ok. Lots of Asian men also have small shafts.
lol you win 🏆 with that comment 😊

If you put the movement sensor on the final output, even if theres backlash the movement wont be registered until the actual output moves. I've used this on a satellite dish positioning system to allow the drive gears to slip in case it crashes into itself. I can still tell the actual position by measuring the movement of the mast instead of the motor's movement, even though the motor is spinning away and slipping.
Great work Jeremy Thank you.
