CIVT: Cam Based Infinitely Variable Transmission

The Cam Based Infinitely Variable Transmission (CIVT) is a novel, highly configurable, ratcheting infinitely variable transmission (IVT) utilizing a three-dimensional camoid (patent pending) based on the operation of a planetary gearset. It is unique in both its operation and its possible applications. It combines the flexibility of both a planetary gearset and a IVT into one package. Unlike other ratcheting IVT's which produce a nonuniform output for a uniform input, this transmission can shape the output to match many periodic waveforms. Therefore, this ratcheting drive has the unique ability to produce a uniform and continuous output.

the video doesnt mean anything unless it is not explained by some one ! oh please. what i can see is just a wheel of time running by a chain. explain it dude..

The blue and yellow markers show me that the the driving gear and driven hear rotate at different rates. Each time they come around they are a little farther apart. But what I don't see is that rate changing, continuously, much less discreetly. You should at least attach two digital tachometers and let us see the read outs as the output rate of rotation changes as the rate changer varies and as the input gear is rotated at a constant angular velocity. Shame to build this and give it 40 sec.

Is is good for a bicycle and what is the reduction ratio, the spread ratio?

[Twizt3dArc]

the voice scared the shit out of me

[rodstartube]

you dont show output dumbass

[clocktwibright]

Summary: it's novel, patented and has unique ability

[tsbrownie]

A. Weighs more than my bicycle

B. I'd have to clean it 6 times a week and it looks like that would be no fun.

C. Don't see the benefits

[stupidYOOTUBE]

i didnt see anyhting what i expected

[oxysean]

i dont get it.

[Skoda130]

I can see how it turns. Not how it works.

Isn't the objective a variable output from a constant input? (Optimum pedal rotation rate and force - slowing down or speeding up based on potential energy gain/loss from going up or downhill?)

Do physicists ride bicycles as a child?
