Infinite Variable Ratio Pulley, How it's made and how works...
HTML-код
- Опубликовано: 21 окт 2024
- In this video with the help of my friend Philippe from Phil’s Projects, you’ll be able to see how this type of infinitely variable ratio pulley is made and we’ll explain how it works with closeups and static demonstrations, this is a different way to make a infinitely variable transmission on some machinery, unlike the other types that needs 2 separate pulleys, one master pulley and a slave one, good example of the later type is widely used on Bridgeport type knee stype milling machines.
Also, I’m sharing with you the reason why I’ve neglected the channel since the beginning of the year, from my parents needing lots of care until the very recent passing away of my dad…

Sorry to hear about your Dad. I lost mine several years ago. Its tough.
Thanks for the explanation. I agree paint is fine, but performance beats paint in my shop.
Always enjoy you and Phil working together. You make it fun and enjoyable to watch.

Sorry to hear about your dad Pierre, lost mine 4 yrs ago and I think about him almost every day...good to see you back
Hi Pierre,
Thanks for the condolences, our parent and loved ones, when they pass away, leave us with some of our best memories...
Like my friend Philippe says" Back on the saddle "
Cheers, Pierre
Sorry to hear abut your father. Cool vide on variable pulleys
Thanks for the condoelnces, life is going on and his spirit is always near by us...
Glad you liked and took a moment to leave a nice comment, Pierre
Sorry to hear you lost your Dad. I lost my Mom a year ago and think about her every day, she had Alzheimer’s. Always remember good times! That’s what they would want.
Love your videos, I’ve learned a lot from you!
Hi Catherine,
Thank you for the condolences, also sorry about your mon, Alzheimer's is lots of time harder for the people that takes care of the sick person. For now my Mom is well taken care of.
Glad you like and you mentioning it is a great reward for doing this... Pierre
Hi Pierre, Sorry to hear about your father, nice explanation, All the best to you and yours.
Hi, Thanks for the condolences, I'll transmit your kind words to the loved ones, Pierre
Great to see you guys again! YAY! So sorry for your loss my friend.
Hi Randy,
Thanks for your condolences...
We're planning to be "Back on saddle" and enjoy the time keping the Channel lively...
Cheers, Pierre
Merry Christmas and Thank You’ll for video
Sorry I'm late, sometimes some comments seems to get all over the place and pop-up all of a sudden from who knows where.... 😕
On this, thanks for the wishes and all the same for you and your loved ones...
Cheers,
Pierre
So sorry to hear about the loss of your father. It is very hard, just remember him in your heart, he will be with you forever.
Thanks for the condolences, our parents are present from the day we're born to the day it's our turn to depart, the bond is strong...
Pierre
Sorry to hear about dear old dad. All the best to you and sorry for your loss! That motor definitely needs some new bearings!
Hi Brian,Thanks for your condolences.
The motor isn't open yet, but hope that a good overhaul will make it perfect...;)
Cheers, Pierre
So sorry for your loss.
Hi Lee,
Thanks for your condolences and for your support, Pierre
Sorry For Your Loss , It's A Tough Time For Anybody . Glad To See You Back ! Amazing To See That Type Of Pulley , Who Wouldda Thunk !!! I learn Something Every Time I Watch Your Videos... Best Regards To You And Your Family
Hi Stephen,
Thanks for condolences, glad to see that you get something good from the videos, the bigger part of the reward is for me... ;)
Cheers, Pierre
hugs for Pierre... great video
Hi Scott,
Nice hug and thanks for being there, things look great for you and Tera also, enjoy your trip to the Bash, sorry I can't be there this year...
Cheers, Pierre
that is a very cool design!
So sorry for your loss Pierre. Remember the good times with your dad. Thanks for the video...
Hi Fred,
My dad left but the memories are always gonne be present...
Thanks for the kind words, Pierre
Sorry to hear about your father. It is always tough. I just finished up the Clausing today and it's variable speed setup. That one is very nice.
Hi Randy,The pain is getting less intense with time, I'll keep the good memories to help keeping on with my own children and family...
'Back on the saddle" just like Philippe would say.... ;)
Cheers, Pierre
Sorry to hear about your mom and dad as that is a difficult season of life. Enjoyed the video!
ATB, Robin
Hi Robin,
Sometimes, getting older, brings wisedom, also some other age related "inconvenients'"...
Thanks for dropping by, Pierre
Just curious. How many segments/slots are there on those pulleys and what is their diameter? Might be a project to make my own! THANKS
Sorry for your loss. My mother had alzheimers too. I love it, two French Canadians teasing each other with English-type puns. Ottawa says hello and I love my Machinist Jacks!!!
Hi Paul,
Thanks for your condolences, alzheimers is a nasty thing to happen, it's worse for the care takers than for the person actually suffering from it, at least during the period where the physical part is still doing good, my dad exhausted himsel taking care of my mother in the last couple of years, he was too proud to accept the offered help most of the time...
French Canadians are a rere breed, keep them alive... lol
Great to hear about the jacks.
Cheers, Pierre
He sounds like my Dad! We had to look after my Dad in order for him to look after my Mom. Not an easy situation. It worked out well but I stoped machining for a longtime. Also a growing family diverted my attention. Now kids are going to Uni and coming close to ending highschool. My wife has given me permission to build a foundary (she is awesome). So, maybe in a few years I will build that foundary. Right now, finish the reno on my shop then the next project.
My condolences Pier. As your buddy was saying back in the saddle. Work is the best medicine.
Thanks for your condolences, being well surrounded with a great family and friends like Philippe, it's gonne be easier to get back to daily stuff...
Pierre
Sorry for your loss. We had the service yesterday for my uncle. He was the guy who got me involved with mechanical things.
That drive is is just like the John Deere Variator drive, just a bit larger.
Sorry about you also lost someone important in your life, they leave a good imprint that's our to make the best of...
Those type of pulleys aren't that popular but they get the job done quite well where they're used... ;)
Thanks for the kind words, Pierre
Losing the ones that actually made an impact is always harder.
John Deere used them for many years on their early lawn/garden tractors. They were used between the engine and a 3 or 4 speed transaxle. The center sliding sheave bushing would get warn and then start sticking or the tractor would set and things rusted up. Most of the owners didn't know they were rebuildable so they sold/junked a very good tractor.
Hello Pierre, so sorry to hear the bad news, be strong and enjoy your memories. I enjoyed the video and seeing you guys in action again.
Thanks for the reference to my hockey team, we've waited a long time out this way.
Hi Howard,
Thanks for the condolences, memories are gonna be with me for the rest of my life even after the pain is gone....
With a little more time now We hope to make things fun like machining and videos... ;)
Cheers, Pierre
Any more vid on how it looks now?
Unfortunately, I didn't do much on the channel since a couple of years, that project is quite at the same state as when the video was filmed....
Sorry to hear about your dad. I lost mine when I was 12. I like constantly variable pulleys just because they change speed so smooth. First one I ever saw was on a moped back in the 60's. Shame it was on such a weak motor. I thought about subscribing like you asked.
Hi Harold,
Thanks for the condolences.
Great to have you as a supporter and a subscriber... lol
Those pulleys are quite fun to use and simple to maintain.
Cheers, Pierre
I am surprised that aluminum (it is aluminum right? ) is tough enough to take constant rubbing from the belts. Are those pulleys cast or machined? I have the same thing on my doall saw but the pulleys are zinc and worn out.
When the pulley moves the diameter effectively changes which effectively changes the length of the belt. How do you maintain tension on the belt? Is there idler pulley or?
As the pulleys change ratio, the pulleys assembly slides along the 2 rods, doing so it compensates and acts to switch the belts required lenght from one side to the other, since the pylleys change their ratios symetrictky.
Let me know if it's clear or not to you... 🙂🙂
@@pierresgarage2687 Thanks. Watched it again and saw where I missed that. Makes perfect sense now.
God Bless You. Sorry about your Father, I was 34 when mine passed. It left a hole, but in truth I was already "The Dad" for the next generation. It made me grow up to realize there was no safety net under my high-wire now, even though I had not fallen.
Hi Wesley,
Thanks for your condolences, our parents can go for any reason at any time, this is something we don't have much say on it, but, they leave us with something inside that will be with us for all of our life...
let's do our very best until our own departure time.
Thanks for your support, Pierre
My deepest condolences to you and your family.
Hi, thanks for the codolences, I'll transmit to the family... Pierre
Sorry for your loss Pierre time will heal. From Elliot Lake.
Hi Scoot,
Thanks for your condolences, in deed time makes better, after almost 2 weeks, it's starting to be a little better, somehow...
Pierre
As one side moves, doesn't it cancel out the other side? Result, no change in outcome speed. I'm missing something.
As one gets smaller the other wheel gets bigger, then, the ratio is is lets say 2 to 1 in one direction, as it shifts to the other side the ratio will be 2 to 1 in the other direction. this setup allows the change without the need to change the length of the belts cause the variable pulleys travel along the slide bars.
You need to figure that the pulleys on the motor and the other one on the driven tool are constant in size. the ratio is directly proportional to the diameter of the drive pulley over the driven one.
Speed Selector makes variable speed pulleys that replace the Reeves and Hi-Lo pulleys. I think they went out of business. A lot of them are in stock or they can make a custom if needed. They have an actual engineer to help you if needed. Very helpful.
I haven't heard about them being out of business, their web site is stibe is still on line....
They have great variable variable speed pulley systems, similar to what is in Bridgeport or similar heads.
The system shown in the video is something different and less usual.
Thanks for your comment... 👍
welcome back !
be strong and know they are free now,....only you suffer and I am sure you are happy to do it for them,...
Passing away is the one thing that is unseparable from life, we all have our date, our parents left us with something that is within ourselves and for lots of us we'll transmit this to our own childrens, so the cycle continues...
Thanks for the good words, Pierre
So sorry to hear that. My condolences.
Hi John,
Thanks for the condolences and for the support, Pierre
Sad news Pierre - never easy. Thoughts your way my friend.
My ancient lathe uses inversely related variable pulleys... useful system. Similar principle to what you showed although mine uses two shafts.
Hi Chris,
Thanks for the kind words and condolences...
Your system sound more like it's the type used in lots of variable speed milling machines of the Bridgeport type, that system works great also... ;)
Cheers, Pierre
Hi Pierre, I was wondering, can you share de dimension, slope, or 3D model of those pulley? I would like to make some for a drill press. Thank you
It depends mostly on the straps you're using, as most straps are in the range of 34 degrees the pulleys have to be in that range, the size of the pulleys is dependent of the ratio you need for reduction or increase. When the straps are on equal diameter on the device there is a 1:1 ratio, as you go in either direction you change that ratio, then you need to decide what ration you need and then the diameter will be determined accordingly, be aware that with a 34 deg. the thickness of the wheels will increase quite rapidly.
Sorry to hear about your loss Pierre. RIP.
Now I kinda feel bad for making a moss on yer mill joke to Phil..RE: Facebook.. ;-)
Hi Colin,
Thanks for your condolences...
Got to take care Philippe, now that I should have a little more time on my hands... ;)
Cheers, Pierre
Sorry to hear about your dad Pierre.
Hi Arthur,
Thanks for your condolences and your support, Pierre
I'm so sorry for your loss......
Hi Jster,
Thanks for your condolences, time will ease the loss and I'll be keeping only the best memories, Pierre
A fun day Pierre. can monkies be on a saddle ?? LOL talk to you soon
Hi Philippe,
Having a friend like you is quite priceless, wish more people would have just that...
See ya soon, Pierre
Condolences Pierre..
Thank you for your condolences, Pierre
My Condolences. RIP Pierre senior.
Hi Barry,
Thanks for condolences and for your support, Pierre
Hi Pierre and Phil !
Sorry to hear your Dad passed away ... allways sad when someone near you isn't there any more.
I can see what Phil brought you ... the cap of the bottle is sticking up the plastic bag just in the buttom of the picture - right ?
That variable speed system er very nifty, clever ... and very simple - what you forgot to show is how the middle part is moved - you are NOT supposed to stick you finger in there to move it, I beleave !
I think that system is invented in Denmark, right ? ;-))
BTW: I like your attitude on FaceBook - I've never been there and I never will !
Hi Keld,
Thanks for the condolences, we'll keep the best memories in our heart...
What you think to be a bottle neck is in reality a handle for a sliding guide for a tool... Don't get your hopes up too much... :)
Uhmmm, seems to you danish people that everything clever comes from Denmark, guess I'll let you dream quietly, sweet dreams... lol
FaceBook is a TOTAL WASTE of time, or at least 99% of it, I rather invest in something with a better ratio of satisfaction, life is too short to waste it with making Zukerberg rich...
Oh, Pierre, just admit it IS a bottle neck ;-))
My condolences, Take care
Hi Paul,
Thanks for your condolences and good words, Pierre
Your father had a long life. My dad died 16 years younger than yours. Be grateful for his long life.
Hi Jeffry,
What also counts, is what they leave us before they pass away, and, what we decide to keep in our hearts...
Thanks for the kind words, Pierre
The motor may be noisy due to the centripital switch, plug it in and find out, but replace the bearings anyway, I'm sure they were in the same environment as the pulley.
rfnoise pretty sure that type of motor doesn't have any centrifugal switch it's a repulsion induction motor the noise is probably from the brushes.
The guy's name says it all it probably "rfnoise" from space... lol
I havent open the motor yet, but your option is still a possible one...
Miss you R...
Understand your loss... lost mine back in 1976. Can only offer that time alone makes it easier.
As to CVTs... have you seen latest models that belt and driver has one flat side? (So belt can run lower and still maintain contact area.) Actually get overdrive of 1.05:1.
Thanks for the condolences and kind words...
Haven't seen the later with the one flat side, I'd be curious to see one... ;)
Cheers, Pierre
Pierre's Garage called TAV2 See them on Amazon, Ebay or omb (old mini bike). As cheap as $60 US. Final ratio should be 0.9:1, not 1.05:1 cometkartsales.com/Comet-Industries-Torque-A-Verter-TAV2-30-Series-Parts/
Pierre's Garage One last bit of trivia about variable ratio pullies. Take a pair of the big "driven" pullies and mount one to a gear takeoff on either side of a differential, and you have steering method that was used on "Snow Trac" vehicles. en.m.wikipedia.org/wiki/Snow_Trac#Mechanicals Only snowcat vehicle I ever saw that used a regular steering wheel for steering. It changed pressure on either side of variable pullies gear driven off output shafts of VW industrial engine and transaxle.
Haven't seen this comment due to RUclips poor comments management, interesting they use this in karts, it looks pretty much like what's in variable type millimg machines heads, quite close to the one I use here...
Like they say, much better than using the brakes in order to steer the snow track, thanks for sending those bits of information... ;)
Hi Pierre, Sorry for your loss, I lost mine 20 odd years ago and still miss him.
Now for a change of subject, I think your motor needs WD40.
Oh and as I promised years ago I have finally uploaded a few videos, you might even find something of interest. Forgive the raw nature footage.

Hi Chris,
Our parents are part of us for all of our life and nothing can break that bond...
I'll take a look at you video within a short while, time to get back to the daily routine... ;)
Thanks for comment and support, Pierre
