Suggestions from Neighbors...
1. Alignment of the pulleys/sheaves can cause problems with vibration and belt damage. This should be checked also.
2. Notched belts are more flexible and are a good addition to a well designed setup.
Technical notes and corrections...
Near the end I talk about small pulleys lowering the HP rating of your belt. There are several factors adding to this that I did not mention. The key forces on the belt are on the "tight"side of the belt entering the small pulley (the main issue I am referring to), the bending of the belt around the small sheave over and over, and the centrifugal forces of moving around the sheaves. These items together help determine the rated hp of the belt. The smallest pulley is the guy creating all of the high stresses on the belt. The only conclusion you should draw is a small pulley might reduce the life of your belt. - Навчання та стиль
I’v been an HVAC mechanic for 29 years and have worked on fan, sheaves and pulleys of all kinds an sizes. I’v worked blower sections as large as a full story of a 40 floor building. I’v worked with mechanical engineers of all levels. My compliments to you my friend you are a great teacher!
Hi fella can I contact you by email I would like to ask you a question on fan touque Dave
Are you in U.K. fella.
This is totally the opposite of reality. The chart shows how much horse power can be transmitted using a larger diameter pulley due to the ability to grip the belt. Your leverage idea works exactly the opposite of how you explained it. The further from the center of rotation the pressure applied will be less, that is true, but when the distance from the center to the point of resistance is greater, the power that is required to create rotation is greater. Think of it this way. If you had a wrench attached to a shaft, as you illustrated, and you had a certain amount of torque applied to the shaft, would it be easier to prevent rotation by placing your hand on the wrench 4" from shaft center or 18" from center. Obviously 18". This, therefore, means it would require much greater HP to rotate a 36" diameter pulley than an 8" pulley.

Been vaguely planning out a custom made table saw build to replace my bodged together upside down circular saw setup and this kind of information is absolutely priceless. Thanks for sharing what you've learned and helping all of us better tinkerers and makers.
So glad I watched this! I am building an apple scratter and have salvaged a motor from a tumble dryer. I searched on youtube for "Can I use a dimmer to slow down rpm on an electric motor" and I found your video on this which has led me to this goldmine of information and motivation. I subscribed and am finding the whole thing fascinating, I am 60 and loving all this new information. Thank you.
You earned my subscription. Every video I have watched from you has kept me listening til the end. Thank you, and please continue making educational videos! The world needs you on UA-cam! Lol
I am honored thank you! Welcome to the neighborhood
I just found your channel last night. I really enjoy the way you explain things and use what you can salvage to build with. I'm an electrical engineering student and avid garage tinkerer of salvaged things. Thank you!
Thank you for taking the time to make this video. You explain the process very well.
Just learned about pulleys in a class i took this semester. We used the same book! Incredible that you condensed the basic concepts down to 6 minutes. Good work!
I've been working on designing a few machines, this video sums up a lot of information I had to find very nicely!
This is excellent. I just built a thickness sander using some of the information from your chanel. Thanks for putting this together it is a great resource
Thanks Jeremy. I am building a Trommel to separate rocks from dirt using a 55 gallon drum cut for screens and driven by a motor and pulleys. This video is very helpful.
This helped me fix my bandsaw's belt issue, thanks!
Very good video, I’ve never thought of it that way till now. You opened my eyes to understand better.
Great video with excellent information! Thank you for your time. It's amazing what folks can accomplish together !
This helped me choose the proper pulleys for my milling machine. Much appreciation for this video!
I really like your videos!! I used to have access to all sizes of motors I changed out, some weren't even damaged or just needed bearings and I gave them away to people I knew in motor rewinding field. I wish I had some of those motors now since watching your videos. Some of the motors were so big it took 2 men to unload but most were 1 to 4 hp. I'm gonna keep my eyes out for some I can strip out of old equipment. Thanks again for your videos
I instantly subscribed. I appreciate your thorough, easy to understand, explanations.
Excellent vid Jermey, you answered my question and taught me a load of pulley info. New sub!
Building a welder generator and needed some of these tips.
Big thanks for the tips, Jeremy.
Thank You again Mr. Fielding. And also for sighting your source book. Very good explanation. And to check alignment , I always carried a straight edge; a piece of string. And a very happy and safe New Year to you and yours sir.
This video was and is so helpful. The info on the power rating for the belt answered my question on why I need 2 belts on my compressor. Thanks!
Your explanation is succinct, helpful and informative. Thanks for sharing.
You and your videos are great too watch and to learn from however those little things might be. Keep at it, and I too wish you and family a very good festive time.
this channel is a complete course for my project.
Great video, had many of the answers I needed to fix my design, thanks Jeremy. Great content?
Superb video. It solved my drill press belt slippage problems. Cheers from Spain.
wonderful video, this is why youtube is so good, it provides those with a wish to learn the best teachers.
Mr. Fielding, I subscribed because I love the information about the components that make up the thing you are making. Not many people take the time to explain how all of these things work. Thank you for your teachings! I look forward to learning more! Thank you! Thank you! Thank you!
👍
Lot of great info......i need to save this video, have a great weekend Jermey
Again one more video for education!
Happy christmas and a good new year to you and your family!
Cheerio from Germany.
Your complexion is at contest with your education. Bravo.
Really love these purely educational videos! I’m working a lot with gt2 timing belts right now for the robot arm I’m building and I’d love to watch a video about timing belts with timing pulleys!
Thank you..twenty years I have been having issues with my boat lift pulleys and belts..the pulleys have been scalloping and causing the belts to slip and burn up.. They too used a very large pulley on the bracket of the lift but a super small pulley on the motor side (the one that always scalloped causing the slip and the belt to burn) this video is late. But again I was having issues and figured I'd UA-cam it to see if anyone else was having the same issues. So glad you did this video.. I was afraid of going to a bigger pulley etc..now with the information you provided perfectly, I understand the issue and can correct it this time!! Thank you very much!! Much appreciate this tutorial!!
Thanks for the video :) I had a vague idea about some of that stuff but it was great to hear it spelled out so clearly.
Hey Jeremy, I have been watching your videos for a bit now and I gotta thank you. I was addicted to taking things apart ever since I was little. I took apart the tv...the new tv... it was not appreciated. You, among a few others have helped me understand what to do with the bits’n’pieces after the deconstruction of a particular thingy. So, thanks again for letting me into your shop for a laugh partner. I hope this finds you doing well.
It does... thanks for sharing 👍
Sir. You are an excellent teacher. Bravo.
your videos are so concise with out all the ramblepeoplenormaly give, hope you make money from it or get some sponsors,thanks for what youdo!
Thank you, Mr. Fielding. I did find this helpful. I never knew that there were so many factors for belts. As well, this explained a mystery I have in my home. That being, why my whole-house fan uses such a skinny belt. The answer was in the first example, wrap.
Once again, good content, keep up the good work.
Fascinating. I wish all my teachers had been able to communicate as well as you do. Thanks.
Minor technical inaccuracy at 5:40: Work = Force x Distance moved. Compared to the shorter wrench, you are using less FORCE with the long wrench, but by moving the handle a greater distance you are doing the same amount of WORK. You are my favorite UA-camr. Keep up the good work (no pun intended)!
Very well organized and great pacing. Thanks!
very informativ and entertaining the same time, thanks for sharing your knowledge!
Excellent video, well explained and has given me some ideas as to what might be wrong with my bandsaw!
Thank you Jeremy. I checked this channel out looking for inspiration. My new ride-on lawnmower was chewing through blade drive belts, which fail to turn the blade, and then overheat by friction and break. The tensioning pulley is inside the belt track and moves outwards to tighten the belt, and in so doing it reduces the lap angle on the driven pulley to 125 degrees. I was stuck on the idea that this was the principal problem. Surprisingly I had Shigleys on my bookshelf but I found no clear indication of minimum lap angle. The realization of the real fault dawned on me after quite some time. As is so often the case, the answer lay not in the highly technical but in the basics. The fact was that the original belts were too long, and while the belt tension appeared to be adequate, in fact the tensioning pulley was at the end of its spring arm travel, and a little warming of the belt was enough to expand a little and allow slip to start. Soon the belt would roast and shred. I fitted a belt just one inch shorter. It increased the tension and the lap angle by 12 degrees. I got my lawn mowed.
I had the same issue. I added a piece of chain from the tensioner arm so I can adapt to different length belts. I went from using 2-3 belts a year to 1 belt lasting 2-3 years.
Jeremy is clear and professional in his delivery! I learned a lot!
Nicely explained. You, sir, have earned another subscriber.
Thanks for this video. You made this very clear.
You have inspired me. I appreciate your thorough, yet simple explanation of a concept that has been complicated by others.
Always good teachings. Thanks again.
Hej, you one of the bests! Your videos are awesome. Thanks a lot and greetings from Germany.
Quite clearly Jeremy knowledge is way above average and explaining it on video even better. Any motor pulley under 75mm is a pain , worth spending a few bucks more and get a cogged belt for those small diameter ones.
Learned a lot from your video. Very well explained. Thank you.
Thank you for sharing. I really enjoyed your video and learned a lot.
Thanks for another vid. It's awesome when you pull out the text book.
Merry Christmas to you and yours Jeremy always like your explanations
Great video. Perfect explanations.
This is such an awesome video. Thanks
Very clear on explaining!
You must be a teacher.?
Thanks for sharing!
Larry
Really helped with my project 👌👌
Thanks for sharing your knowledge! I learned a lot here.
Excellent mate BETTER THEN ANY teachers I had
Very interesting, thanks. So much to learn, so little time.
This is exactly what I was looking for.
Oh, BTW that homebuilt bandsaw is awesome. I came to this site because I have a contrary rototiller and I thought it might be the design and belt wrap. After watching this I have figured it out!
Your craftsmanship and ingenuity is undeniable. (HVAC-R trained and I work on freeze dryers lyophilizers)
Thank you!
The last part about the belt rating per pully size had me thinking for a while. I understand it now but it wasn't something I'd considered before...thanks!
I added a note to the description which gives more detail on this.
Sooooooooo informative. EXCELLENT and many thanks!!
You ave answered to my questions i had for almost a month
Very interesting observations and wishing you and yours a very happy Christmas 🎄🌨⛪.
Great info as always!
This is awesome way of explanation
Thank you. Short video, but learn a lot.
Happy New year Jeremy!
Dang dude. You are super smart! Thanks for the great info
Good video Jeremy! Merry Christmas to your family
I'm learning a lot. Thanks.
thanks dude! you've got this all under your belt
Thanks for this. My belt was squeaking on my new car build. Turns out the mechanic used an A belt, when the 400hp/tq engine needs at least a 1.5" belt per your book. I've ordered a new pulley/belt set.
fabulous video
What a great explainer.
Great explanation
Very helpful man! great video
thank you, you helped me very well,you are a great teacher
I really liked the video and it has helped me quite a bit.
Thank you sir! Great info.
Really good video! Your explanation, along with the demonstration, made it super easy to understand some of the issues faced when dealing with v-belts.
Thanks for making this!
Good Information.
Merry Christmas and Happy New Year to you and your Family
Very useful info, thank you!
Just discovered this channel - it's awesome. Great video, so useful.
Thank you, and welcome to the neighborhood!
Very helpful. Thanks!
Very helpful. Thank You
Thanks again for another informative video. I have no comments. I would just like to wish you and yours a Merry Christmas and thank you for all your help this year.
Very informative, thanks for sharing.
Great video!
love this channel
Informative and interesting video. Thanks
I find the best way to visualise the pulley ratios is to think of a bicycle. The fastest speed is a big chain ring with a small rear cog. For hill climbs a small front cog and a big rear cog does the trick. Great video thanks!
Your my hero, it has taken 75 years of life to find you.
awesome information thank you
Very useful!
