Innovative Transmission

IMHO no, not a big market.

But I may be wrong.

Cycloidal transmissions fall nicely into this range. They seem to be robust, but toward the expensive side. Multistage planetary is another option.

Well it would depend on the application.

Is this for a low torque application (like an air drill), a heavy torque application (like a large horsepower industrial motor or vehicle), or something in between?

Can you provide a little more detail on the intended application and market?

Is the idea you, "came across" yours?

In planetary transmission it is already there with two annular gears with different number of teeth (I forgot the name of that but it is quite common). It has a capacity of bringing up even larger ratios. And then you migh have multistage planetaries too.

If you have something else, and it is higher efficiency of transmission why not patent it? Afterall if the concept is new it might always be modified.

The question is if there would be a big market for such transmissions? Of Course

If there would be a market, I would like to patent it, but I wouldn't like to spend money for patenting if there would be no real demand!You can Launch immediately saying Patent Applied For

Warning: Efficiency Less than Worm Gear-- Remember -Worm is Bad enough

Suggest: Epicyclic - High Efficiency at 1:70 ,Light,Not expensive .

Indian Companies Produce a lot of these.

Catch 22 old chum,without patent you can't disclose, if you disclose you can't patent,What to do what to do.

'...What to do what to do...'

.

It the idea warrants protection, file a PPA (provisional patent application) it is cheap, quick, and provides protection for one year, during which time you can prepare the patent, gather investors, sell the idea, etc.

A PPA is not without its own set of pitfalls however...

There is a very simple high gearing unit in the US - unable to find the link at this time,
where a driven ribbed/serrated spindle presses on the circumference of a tyred wheel.

They claim ratio's of 100:1 etc. with good efficiency, at a very low unit cost.

If you do a few searches they should still be available, which may help you avoid
re-inventing the wheel? I would advise certainly not spending a lot of money on
patents without undertaking considerable research of the market first.

Hope this helps, jt.

One Drunk says to another,...... "Do you drink to excess?"

His mate replies, "Me? I'll drink to anything!"

That sounds like a variable-speed drive. That could be a bonus!

We used to use a variable drive system back in the80s that was two sets of cones face to face with slots that ran from the outside to the middle of each disc, where you had a slot on one side you had none on the opposing disc, a belt made up of small sliders that located in the slots ran between the two sets of cones,the idea was to push one set of cones together which would make the belt move to the outside of the one that you're pushing then the other set would open-up to allow the belt to move towards the centre,you'r ajusting the diameters and therefore ajusting the speed, this idea was for a short time used by DAF to drive a car only they ajusted the speed automaticly.

Look for as "cycloidal drive" in the Wiki, is Asomething like that? no? cool!!!!patent it or give us (the humanity) free of charge.-

You can write up your idea and file a provisional patent application to secure your priority date. After you have filed this, you can say "patent pending" and people will feel more at ease about discussing your idea. You need to do a thorough patent search, which will be a few weeks of work. Here are some resources for doing your patent search: (1) the PTO Manual of Classification and (2) the FreePatentsOnline site. You will need to find out which class/subclass your invention is in and look at the patents and other publications that pertain to that in order to focus on what is new and patentably different about what you are thinking of. Your ideas will probably evolve as you do your search.

You mean like belt and pulley? I think it's been done...

Yes but the pulleys are split so they can move in & out, also with the belt/chain able to they are able to vary the diameters thus altering speed, I've seen two types of this, one with smooth discs with an ordinary vee belt which worked quite well, and the one with slotted discs & chain belt that cannot slip, both are good for the purpose they are designed for.
