gear train size

[Ilario]

Can't you mount n gearboxes in series? ? ?
I mean, the engine makes 600 rpm, so 864000 rpm per day
your reducer has 1:600 and takes you already to 1440 turns per day
one more with 1:600 six at 2.4 turns per day
with a pair of gears you can get ratio 1:2.4
but also with a toothed belt.. .

It's a little more complicated than that, I have to work on tight enough spaces, and it's not just about having to reduce angular speed. . In short, I have the need to calculate the series of gears that make up the series trying to use as little as possible. But maybe you enlightened me on the question of wheel relations... I see now.

 

[Ilario]

Is that right as reasoning?

n = n° r/day final gear = 1
n1 = n° r/day initial gear = 1440
u = gear ratio = 1:1440

If you want to put intermediate gears, I should break 1440, so:

1:1440 = 1:720 x 1:2

then:

1st gear = 1440 rpm
2nd gear = 720 rpm/day
3rd gear = 2 turns/day
4th gear = 1 rpm/day

Is that right? only to understand if the reasoning is correct, of course that will not be these the turns that I will adopt.

Yes, the concept is that
in practice, for each reduction it is difficult to go beyond ratio 1:3
so, the number of gears increases.... and so much also !!!

Are you sure that from business you find nothing suitable for purpose?

....

boh, I honestly don't know, but I don't think that's so specific. I don't even know what to look for.... I've already realized that it will be another stripper like that of the venturi and I won't give a solution. . Of course, I'll have to arrange because there's no one here (in the company I mean) who can help me... my only source is you and my fight in research. . .

It would be nice to have you here to make you understand the final intent and also to exchange cultures with competent people, but you cannot))

What if you let this guy's gear stay?
other solutions, such as:
- epicyclical gears
- Harmonic drive
- cyclo drive

of course not to design, but to buy. . .

 

[MBT]

I also thought of Sumetom and epicloid. . .
but I have no experience with such small powers.

not to discourage ilary, but to draw a train gears with a reduction of the genus is from gastroenterite, especially if it is the first case. between gears, axes, bearings and supports blows out an incredible whistle.
and it is not said that you save compared to looking for business solutions.. . .

I'll correct you.
- besides gastroenteritis you have forgotten liver, heart and family problems
- unless you work for free, it is practically impossible to save compared to business solutions. you study the problem in this way only as last beach.

It's that I already have them...
and gastroenteritis is an indescribable annoying!!!

but even if you work for free.. .
You put a month of work on it, they are unheard of the disasters that you find yourself in the assembly if something doesn't work!
I found myself in his situation, rather than studying an 8-9 stages of reduction I take the phone and start tightening my usual suppliers and even occasional ones by the neck, until I find myself an offer of a suitable reducer!
