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......
@ronarmstrong83510 ай бұрын
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.

The Inventors episode that I cannot find. This is as close as I've seen. ...no news though... Torque kills these gearboxes, as the infinite ratio at low end causes massive stresses. I believe high speed harmonics can be an issue also.

@carmelpule69546 жыл бұрын
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.

@marcinszewski37145 жыл бұрын
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.
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.

@durexyl3 жыл бұрын
@@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.

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.

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)
