Multistage reducer?

[PaoloColombani]

for an industrial atrezzatura I would need a reducer with a very strong reduction ratio, I should get to the shaft 0.005 rpm, about 50 n/m at most. the ideal would start from a small asynchronous motor possible without resorting to an inverter (network frequency). Any advice?

I imagine you've already looked at epicloids like techno-engineering or sumitomo or alpha (or how the hell they are now). for strong reductions exist the "armonic drive" of not remember which producer but I think they cost very expensive.

But I understand, do you need a 1:280.000 report? Maybe by cascading three epicycloids you can do it.

Harmonic drive and cyclo drive are a solution, but only if you need certain features, and are quite expensive.
What do you have against the old endless lives? Maybe precarious if you want to avoid games?

I have consulted the catalog of motovary (that as most generic usage gearboxes are made up of an endless crown-driven couple) but making some accounts to achieve such a reduction ratio I should go on a three-stage configuration (perhaps it would come out a little bit too pacchiana).
otherwise I should build an ad hoc reducer with a large diameter crown. I must make two accounts.

of the harmonic drive I didn't even open the catalog, I could try regret to use a ferrari on a country road. Unfortunately, I must also look at the final costs of the object. It is not a motion control application, I must only draw a thin foil.
yes the relationship is about that. but using a 12 500 rpm poles, I could go down to a ratio of 1:100 qu000

1:100.000 is a Mr. report.
the smaller engines have powers from 0.09 kw, if not erro.
You need a lot less. You could use a motorcycle-changer with gearbox.
If I don't go out with the bike-changer, you get up to 1000:1 ratios, then you put a downstream reducer.
the eye that the couples that come out will be ouch and therefore you must safeguard the weak link.
Hi.

with a bonfiglioli vf/vf reducer you can get to 6000. putting us behind another 50 report reducer comes as much as you need. If the application doesn't need precision you can try like this.

but at this point, considering the containment of costs, put a hydraulic motor powered by a pump? saving in the driver and still obtain a smooth movement

I realize now that I write that in fact almost 300000 reduction ratio takes space also considering pump that from a spit

stepper scooter (http://www.twintec.it/motori_passo_passo.htm) Low frequency controlled with coupled gearbox.
It's just an idea, I didn't evaluate it technically.

Bye.

Thank you all for the advice, always useful.
in the end we have solved by identifying a normal screw reducer and pre-pair with a more "human" reduction ratio, however, using a discontinuous motion (attach detachment) that is reconciled well with the application.
