people are saying this was recorded on a VHS tape in 95'. my parent's wedding recording is in high resolution than this, also, you hear that? *its the joke going over your head*
I saw one of these on an old TV show called "The Inventors " on ABC TV in Australia in the 1970s. It had a panel of experts including an engineer, who was fascinated. He said he could see what was happening, ( the varying output shaft speed) but couldn't understand how it was happening. The inventor said it worked by varying eccentricity. Apparently it was much more efficient than a normal gearbox. I always wondered why it never became commonplace for so many applications......
Given how old this is, I don't know if you'll see it. I've been looking at drives like this for the last two weeks. The first system was called a D drive. Its inventor was apparently heckled by trolls till he left the scene. This type of drive is now showing up in different forms like the Inception drive. All use some form of variable eccentricity.
This Variable gearbox has been rehashed many times. Many years ago I thought I was on to something, but was soon to learn that I was at least 25 years to late, when I was informed by my Engineer boss of its use was in some US WW11 Tanks.
I am acquainted with old marine gearboxes with a forward, free and reverse position and it has a differential arrangement and a brake band where the differential can be locked for ahead, free for free and lock the brake band for reverse. For any speed I can slip the brake band. It all works because of the characteristics of the differential unit. Then there are the automatic gearboxes with a set of planetary gears which again , clutches bring in an out the different ratios of the planetary gear selected. I would not call these an infinite gear system as they depend on slip is one needs a variable gear. I had a moped a long time ago which had an infinite gear ration and depended on a pulley whose faces change and a belt rides the surfaces at different radii. I still do not fully comprehend the infinite action of this unit, but good luck with it.
Judging by the eccentric piece, this is probably a ratcheting CVT coupled with a bevel gear box to combine the constant speed input with the variable speed of the ratchet drive. Very similar to the power split of the eCVT in a prius, but the electric motor is replaced with a ratcheting CVT.
For the detractors of the system (see the comments), practical or not, it is explained, all the automatic gearboxes work on the principle of the mechanical Differential, locking a block of the planetary differential between both speeds up the another and vice versa
Para os detractores do sistema (vê-se nos comentários),prático ou não, cabe explicar-se,todas as caixas de velocidades automáticas funcionam sobre o princípio do Diferencial mecânico,travando-se um bloco de planetários o diferencial entre ambos acelera o outro e vice-versa
Interesting idea. If the mechanism is capable of transmitting sufficient torque, I could see this having applications in many workshop machines, like lathes, Milling machines and drills.
Mechanisms to do that have been around for 80+ years, and are in those very tools you've listed. Especially Bandsaws, mostly vertical bandsaws. It's just not in $100 harbor freight drill presses.
I want to see a full-mechanical-lockup variable speed drive. There is a good reason why this is not utilized with every single adjustable-speed mechanical device on the planet right now..... and it's not the cost.
Nice design! I saw a different design on CZcams a while back that was variable and went forward to neutral and neutral to reverse . And I can't find it anymore . Maybe someone can post it again ? It would be fantastic for a car transmission no parking brake needed. engine off it won't move, srart it, and it won't move, until you actuate it into forward or reverse.
The disadvantage of such transmissions is that they are pulsed. The moment transmitted during one revolution of the drive shaft can vary from a maximum value to zero as many times as the MCA is placed around the circumference, for example, five. In this case, a complete torque pulse is transmitted in turn through each MoA, while the others at this time operate in the free-wheeling mode.
I saw another video with the same principle and it to achieve different speeds made losing power, then a lower speeds require more power than regular transmission to deliver the same power to the wheels. it looks like the old automatic transmissions where there is a brake belt to stop the planetary gear to change next speed.
i just can not believe someone hasn't`t come up with a mechanical variable speed transmission system that would have been excellent with the old mack trucks no smoke and effiecency out of this world
Basically, with a differential type mechanism the more braking force you apply to one side of the assembly the faster the other side rotates.......take all the braking force off and it will freewheel......progressively apply a braking force to one side and you have a variable speed output......a simple torque converter principle.
Wow, what a lot of nay-saying! Internet is good for that to be sure. Cannot say much about your engineering, don't know your intent, but the music was swEET! I added to my music list. One man's Mozart, another's Stravinsky perhaps, but I dig it. Thanks for sharing!
Basically you reinvented the planetary gear, as it is used in the Toyota Hybrid engines. There it is used to combine the combustion engine (the inner rotor) with the main electric motor (which is at the outer ring). The Planets are controlled by a second electric motor, which can also work as generator (thus acting as a brake) In this combination it is a very powerful and simple gearbox with an enormous efficiency.
sploofmonkey - that's because "climatic warming is a hoax". I heard him say it. It's all to benefit the Chinese, who are way ahead I the manufacture of solar cells and turbine blades. I agree with you - if Trump wants to "make America great", whether again or not, he should be pushing the sort of industries that will be viable in a future world, not re-opening coal mines.
Lead or lithium batteries are recyclable and contained in a shell, while engines burn and puke oil, gas and metal their entire lives. The mines for lead and lithium are a fraction of the size and pollution of the mines for steel and aluminum, which are what 99% of the car is made of.
Agreed, but I don't see the two motors.(MG1, MG2) I don't see the wiring needed, to supply or recirculate the current between the two motors. In the E-CVT, the differential carrier is part of the final drive, not the epicyclic gear set.
It struck me as similar to that, as well. Here you are able to shift the planet gears so they are asymmetrical to change the torque split between left and right halves of the diff. Pretty interesting. No, it isn't using conical gears, as some have said, and it isn't using friction, as far as I can see. Changing ratios by changing radius of the planet carrier. Actually pretty clever.
Indeed. "Look at this box that you can't see inside that allows variable transmission!" Almost as bad as those "perpetual motion" videos. I feel scammed. I should have guessed this was a lie before I even clicked, but you never know.
So in a sense it is a constant speed drive or CSD. Its used in aviation on the engines for the generators or anything that requires a constant speed. Interesting tho
The large ring on the eccentric portion is what drives the output side by friction, but only at a small contact point between the two. Did you notice when the arm reached a certain point (about 60 degrees from start), it slowed down again? This would amazing for a bicycle hub if it could go about 6:1. I see why it never made it.
This would have an application for metal lathes. Traditionally you had Kopp variators like on the Colchester Chipmaster, standard Norton style gearboxes and then VFD's. Kopp variators are good and have high torque in the low ranges similar to this, VFD's do not.
Was ich verstanden habe: 1) Ziel: Ein CVT (continously variable transmission) Getriebe zu bauen. 2) Es existiert ein Prototyp (immerhin) 3) Ein gewisser Effekt ist messbar 4) Das Ding besteht im wesentlichen aus einem Differential, einem Planetengetriebe und einer Exzenterscheibe. Was ich nicht verstanden habe: 1) Das Video ist von 1995!! Sollte das Getriebe einen Vorteil verglichen mit existierenden Lösungen haben, wäre es schon lange am Markt. Also: wo ist der Haken? 2) Wie funktioniert es? Wozu dient die Exzenterscheibe? Der Funktionsmechanismus erschliesst sich mir nicht aus dem Video.
Not possible to endlessly variable gear if the gears have same diameter. But if you somehow can change the diameter and center of the gearwheel you can make such a gearbox 🙂
There's really not much going on there that a well-outfitted 1890's era machine shop couldn't handle to be honest. A C96 handgun is ten times as intricate as anything seen in this video. Not to mention watches. Look into vintage machines, engines, and manufacturing capabilities and you'll realize humanity and the average mind have been heavily devolving since 1900. Gears and bearings are nothing to make. It's just the thought on how to arrange them into something new that people tend to get held-up on
From 0:13 to 0.16, the sun gear seems to be off-centered. Is that what you are doing on the physical system from 1:15 to 1:18? I don't gear how your speed can vary with this manupulation
el sistema de diferencial si se usa en vehículos pero todo el sistema puede usarse o se usa en algún vehículo automotor? Derrepente como remplazo de caja de cambios?

Увеличение крутящего момента ценою потери мощности на результирующем валу. Ну, не знаю... возможно в кондиционерах найдётся применение, для плавной регулировки скорости вращения вентилятора, только... электрическая регулировка - эффективнее.
If it truly was a gearbox with "endlessly variable" ratio, it would have been worth Nobel Prize, if not more... The crappy video quality suggests the project never got any further.
Why exactly? As I understand it, it's not that hard to achieve this with differential and for example planetary gears. The real problem is mechanical loss due to friction. But hey, I am not an engineer.
@@petpaltea exactly, the losses are what you want to avoid. Basically, if the gearbox uses some kind of a slipping mechanism to achieve the "smoothnes" of variable ratio, there will always be losses within it, so instead of transferring as much power as you can, you have to waste a proportional amount of it. Plus I don't think this one actually makes the torque go up when the speed goes down, as one would expect from a gearbox... A variator is an example of a transmission with infinitely variable "gear" ratio, but the losses due to friction are still higher compared to traditional gears.
This differential allows a very high torque multiplication. This allows you to adjust speed with a very small torque electric input without taking the entire load.
If I understand what I saw, there is too much loss of energy when the system is clutched/braked. This old mechanical idea has been around for over 100 years. Nothing new here.
@Shoestring Stacker yes, i have a Nissan Altima with only 92k miles and the CVT doesn't feel the same as it used to. Im guessing ill have to rebuild it before 100k, well at least the car gets awesome millage, making up for the week transmission, thats on of the reason why the millage is good, light-weight transmission. Thanks for the awesome comment!
@Shoestring Stacker 1.2L? are you sure? that is like 2 Vespa engines bro! Mitsubishi stock stereos are actually really good, my 2015 Nissan Altima SV 2.3L has good sound, but the rear 6x9 speakers are 50 watt at 2 ohms! (2 ohms? WTF?), so the bass sucks ass bad, 2 ohms is not enough resistance unless your putting the speaker in a sealed box or using a quality amplifier, but i still say its a bad idea, your better off over-loading speakers; then an amplifier. The problem is the speaker is too efficient and moves way too much creating a lot of volume, even at low volume and the bass turned all the way down; the speaker is too efficient and moves so much that bass volume does not match the other frequencies. (this is also a good way to blow your amplifier, using speakers with very low resistance)
nice, good amp! and yes, Im talking about impedance basically, impedance is the ohm measurement for an output though, like a pre-amp, but same thing we are talking about. I used to work for Harmon and Kardon building amps and eq's back in mid 80's, i used my employee discount to order some auto amplifiers (we only made home units) anyway, I had two JBL 180 watt amps in the back and a kenwood 4 channel amp under the seat to power the front speakers. Total I had 21 speakers (including the 3-way / 4-way speakers counted as a separate speakers) so i had some 3 inch 3-way blaupunkts in the dash, some kenwood 4-way 5 inch in the doors, some 7x10 (6x9 adapting brackets) kenwoods in the back (4 way) and 2 12 inch JBL subwoofers in a band-pass box i had to support with my car jack in a VW Golf, all at 4 ohms except the 2 woofers I ran in series to get 2 ohms, man the fucking car cranked! only 1100 watts, but all RMS!
I need one of these if it can achieve 98% efficiency in super thin oil. I need 1:1 to 2:1 gear ratio adjustability. I am only spinning a VAWT wind turbine at 40 to 80 RPM.
1:18, the finest bass drop throughout the land. I want to munch some eccies and listen to this on repeat till sunday morning.
Not clarifying anything. Probably just friction loss that creates a speed difference

nice work. Nobody noticed the unidirectional clutch / bearing you used
They did not want to reveal the uni dir clutch and the eccentricity creating arm

Very similar to the power split of the eCVT in a prius, but the electric motor is replaced with a ratcheting CVT.
That's probably a plausible explanation of it, there just wasn't enough detail in this video, to figure out how this thing works.
What is the overall ratio range that it can achieve?

Total I had 21 speakers (including the 3-way / 4-way speakers counted as a separate speakers) so i had some 3 inch 3-way blaupunkts in the dash, some kenwood 4-way 5 inch in the doors, some 7x10 (6x9 adapting brackets) kenwoods in the back (4 way) and 2 12 inch JBL subwoofers in a band-pass box i had to support with my car jack in a VW Golf, all at 4 ohms except the 2 woofers I ran in series to get 2 ohms, man the fucking car cranked! only 1100 watts, but all RMS!
@Shoestring Stacker oh snap, dont have that car anymore, I have my Nissan Altima now. I build my own systems, I love it, take care buddy
WOW))) It is can be installed in the sportcar?
best on slow cars, CVT on a sportscar is hell
I need one of these if it can achieve 98% efficiency in super thin oil. I need 1:1 to 2:1 gear ratio adjustability. I am only spinning a VAWT wind turbine at 40 to 80 RPM.
