Gearbox Company Names

Go here: Search GlobalSpec

I have checked there, but most of the products listed there are only smaller sizes. There were some companies provide high power, and I have contacted them, none of them fit my criteria.

I would phone just about any gearbox company and ask if they offer what you need. If not, they may know of another manufacturer who does.

Thanks mate. I did make phone calls, but most of them produce speed reducer, so do the company names they told me.

Speed increasers may not be especially common. If possible, it may be better to enlarge the driven component so as to operate at the slower prime mover speed.

(I once designed refrigerant screw compressor packages each way, and it turned out that the larger/slower compressor was better on all counts of cost, maintenance, noise, and longevity.)

It is a brilliant thought, but that would cost a lot of time on discussion about the ideas, design and cost calculation.

Try calling a gear manufacturer and talk to someone in their engineering department or try a gear manufacturers association and perhaps they can point you in the correct direction.

That's thousands of horsepower!!!!

Is this a ship or a locomotive or something like that?

yep, that's a big thing. it's going to be connected with a centrifugal compressor.

Would a 2-pole (3000 rpm) motor, with a somewhat larger compressor, be workable?

Have you looked at Benzlers yet?

They do custom boxes.
