can we turn 10rpm into 1500rpm mechanically?
« on: December 13, 2014, 12:54:33 PM »
Hi follks
can we turn 10rpm with some torque torque into 1500rpm mechanically?   perhaps a stupid question from a person who dont know much about this.
can someone help me out how i could turn very low rpm into  high rpm with mechanical means?
is it possible at all. 
??

thanks

Use a bicycle transmission. Big chainwheel, little cassette.

Thanks TinslKoala
in terms of efficiency,
how many percent of energy is being lost during this conversion?   rough estimate

Thank you

He needs a 150:1 ratio, TK. Tall order. Certainly, a custom made big wheel small wheel system would work or a gearbox or two.

A 10:1 and a 15:1,  and with each being at 97% with good quality chains and sprockets is not a huge loss.

Yes, the standard engineering rule of thumb is that a setup of two sprockets and a chain, any ratio, loses between 1% and 10% depending on the perfection of your installation.

Likewise, in a gear train, any situation of two gearwheels meshing together loses 10%.

Don't clearly remember the numbers for belt drives, but think about many motorcycle riders who have converted their scoots from factory belt drive to chain drive for higher performance. Probably about 5% loss for timing belt type drive and 10% for car fan belt flanged drive.

I would suspect that the most efficient type of drive would be a pure friction system. Two toothless wheels spinning together, like a car tire on a chassis dynamometer pulley. Don't know of any commercially available, and you would surely have fits making one.

great, thanks for all the replies.
and also what Diameter wheels do i need if the shaft which needs to turn at 1500rpm is 15cm in diameter?

and Cangas, are you refering to something like this?  the two wheels just touching and have no cogs?  what do i need to do so they wont slip? or may be draw it down. :D
thankks

VTANGENTIAL_1 = w1*2pi*r1 = VTANGENTIAL_2 = w2*2pi*r2

d2 = 1500rpm*15cm/10rpm = 2250cm

Better to use two reductions of 10:1 and 15:1, or three reductions of: 6:1, 5:1, and 5:1

As we have seen, Yes. But don't forget that there will not be much urge left in your shaft.

I seem to have made a distraction which I did not intend to do. I have a perfectionist streak which is often unnecessary.

In the words of a famous starship captain, this thread's enterprise should be able to ignore perfect efficiency, and, use efficiency that is crude, but, effective. 

Someone has made an excellent suggestion to use off-the-shelf bicycle components to, I suppose, make up a Proof-Of-Principle prototype of an interesting mechanical device. Bicycle chain drive components can most certainly give cheap, proven, and highly efficient, components for such a mechanism. By the engineering rule-of-thumb, a 2-stage chain drive setup could possibly lose only 1% of the power in each stage. You would have to be very finicky about having everything aligned just right, and lubricated well, and such like, and you could use the 2-stage system suggested and only lose possibly 2% of your input power to friction, using cheap, easily obtainable parts.

If you are testing an interesting OU idea, and it is a real RUNNER, it will not need to have every last little 1% of efficiency to work good. Whoever's suggestion of bicycle chain drive stuff should work out great.
