motor gear inertia generator -new help

[justawatt]

Hi i came across a patent ,which has a starter motor then set of gears then bottom gear is looped back till the start and generator.

i am sharing the diagram ,can some one hear know how to calculate the gear ratio ,i would like to make this device ,all the gears are available
in the market ,but if someone who can help to design gear do help.

Do you have a link to the patent?


I'm not able to look at the photos, Stephan still hasn't fixed the mobile html resized settings.


Gears are a little different than pulleys
It's not just the size, but also tooth count, and angle has some effects as well.

The simple fact that large gears are coupled to smaller gears removes all possibility of "inertia".

This patent is totally useless and will only generate friction between those gear teeth.

Please do not waste any time trying to make this because it has less then zero merit.

This is true with most gears, as they are made with high frictional coefficients.
This does not have to be the case, as evident in R/C race cars.
Where the inertia DOES present itself in a prominent way.
Perfectly matched, well lubricated gears can carry their momentum for quite some time.


That's probably why the inventor said things like "those skilled in the art", in contrast to
"those who are not very good at it".


Gears can be less frictional than belts and pulleys (under tension)
When they are made well.


Gears can also be made poorly, or from the wrong materials.
For instance, elasticity has a large negative effect. Which is why metal and ceramic gears
work better than plastic ones.


In the automotive industry, gears are intentionally given higher friction, and heavy lubricants,
BECAUSE of the extreme momenta involved.
Otherwise the inertia of your 2ton car would destroy the driveshaft and transmission gears.


I can't make any judgment of such a convoluted machine at first glance,
Without experimental testing of the device.
But just because it uses gears, doesn't mean it's off the table.
