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.
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 agree Mr. Fielding you are a good teacher.
This is one of my favorite channels ever. I wish this type of content would be promoted to kids and schools in general
Still one of the best KZheadrs out there. I am living vicariously through this gentleman.
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!🛠
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
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.
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.
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!
Congrats from the Most Bestest Wannabe Fabricatorizer Ever! Keep on DIYing!
I still can't believe you made a robot arm like that in your garage. It's honestly amazing. And inspiring.
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.
@hippie-io7225 you're right. It's an incredible time to get into it. I donate learning kits and gear to people all the time.
@@hippie-io7225 Thankyou Sir for your kind words 🙂
@@jstro-hobbytech Thankyou Sir :)
I wish you were my mechanical engineering teacher. You explain designs in a way it makes total sense. Keep up the Great work. Thanks Jim
This video will mesh well with a lot of people
Another excellent video. You have a gift for explaining complicated concepts to simple people like me. Thanks for your time!
I like his channel because he explains every thing as if he is right there with you for your understanding.
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!
Automatic like for all of Jeremy's videos!
Genius and a master at explaining complex terms and ideas in a manner that most can understand
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 💪
Yet another incredible video. You are amazing Jeremy. Thanks!
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.
Bro. I absolutely love your vids. You're a blessing to nerds and knuckle heads as well. I'm a knuckle head with nerd aspirations.
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 KZhead 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!!
Years ago I built Analoh computers. Many gears and wheels. It was a chure to have no "Back Lash" in the gears. Keep at it!!
Never subscribed to a channel so fast. great content, great personality.
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.
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 :)
Dumb EE here trying to do mech things. Video is perfect timing!!!!
But wait, there's more! Forced child labor! I approve (as one who used his kids in his business.)
Thanks for the great content as usual, Jeremy.
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. 👍👍👍
Thank you sir for the kind words. I am honored
Great lecture on gears. Can't wait for part 2!
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.
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 KZhead videos! I said two clocks in the video but there were actually three. And all three have videos.
This channel inspired me to go back to school for mechanical engineering
And Yes I will buy you a Coffee and donate to your Patreon page if i can Avoid buying a whole new motor!! Thanks Pal!
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.
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!
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!
You never disappoint. Thank you for being so freaking awesome.
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
that's great that your teaching your kids about engineering
I love gears. Im so excited to watch this video.
Thank you, you are the man. I hope your kids and friends are learning from you. Your probably the only guy in town with a real robot in his garage.
Thank you very much Jeremy. I love your videos. They teach us a lot. Keep sharing please. Best luck!
I don't think any single YTer has as many vids on my "How-To" playlist as you do! ❤⚙🔨
Great video. Lots of info that I thought I knew, but really didn’t. Thank you.
Nerdy details are great!
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!
i feel that i had to take notes! so much value in those videos! thank you for sharing your knowledge ❤
I Watched this video many times and I always giggled about the way you motivate your kids.
Nice to see you again... for some reason I wasn't getting any notifications for a long time... but here you are, looks like a great topic !
Food service machines need to be able to handle caustic washdown usually as well. Built a fair few automation machines at a previous job that were all stainless, and all belts, motors, actuators, pneumatics, etc had to be able to handle caustic washdown. That stuff is insanely not cheap, like tens of thousands for a single motor w/ gearbox
Fantastic video, as always! Looking forward to part 2!
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.
Jeremy I love your enthusiasm for everything you teach us! Thank you for sharing your wisdom with the world
You had me at the Kid Work analogy! Also, another exceptional lesson! Thank you! I knew I saved those motors for something!!
one of the main benefits of using a worm gear is that it cant be back driven from the output shaft so it also functions as a position lock.
Awesome video Jeremy, I've been wanting to see something like this for a long time ! keep up the great work !
That was super useful in my spacetime. Thank you.
Love this. Thank you
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.
Your enthusiasm is infectious !!!
Very informative. Thank you!
You have such an amazing channel thank you for doing what you do.
When you mentioned bevel gears, I was expecting you to bring up "crown gears" also - they're not common anymore, but they were used for a long time and they might still have some niche use cases, like they normally mesh very well with spur gears, giving them a cost advantage, because it's only one complex gear to manufacture, not two as with bevel gears.
This information is gold. Thank you
Awesome instructions
I just joined - this is *EXACTLY* the survey I've needed.
Excellent information, thanks!
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.
Indeed there is often an abundance of information about components available
Thank You Jeremy 🌹
Thanks for sharing 🎉
Great information and education plus fun with your kids. That's a win win.
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.
Brilliant video…thanks for sharing! 👍
I love this. Thank you for the awesome video!!
Your videos are superb! This is great overview of mechanical drive options.
This guy is a genius!!
Perfect timing, and great content/presentation. Subscribed!
Awesome video! Haven't seen a lot of your videos on my feed lately. Have to dive back in to all your recent stuff; I forgot how good your stuff is!
Thanks for making this video and all your video's. Knowledge and love, the two best things to share.
Excellent explanation.
Always great Jeremy.
Love the " nerdy" details. Thanks for all your details....
Great resource content. Thanks for sharing and putting in the effort (videos are harder than most people think!)
Thanks!
Great video Jeremy!
Nice! A lot of useful information there
Love gears!!!!! Thank you!
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 .
Great video, I have learn a lot, thank you from New Zealand.
Love your videos.
great explanation
Thank you!!
Applied some motivation...I almost fell out of my chair!
Excellent!
Jeremy explaining gears! YES!
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)
Dude. Awesome as always.
Very nice content buddy... I might need to refer to this one in one of my next vids..
great job man!! I really enjoyed your video, it is the first time I have seen you cause you do stuff that is a bit out of my normal, I am a woodworker but I love making things and being able to understand the basics of pulleys/gears will help in that. again great job
