A user is seeking a gearbox similar to those used in wind turbines, specifically needing an input RPM of 1 and an output of 1500 RPM. The discussion highlights the importance of additional specifications such as power, lifetime, cost, weight, size, and efficiency for a more tailored recommendation. It notes that while utility wind turbines are designed for a 20-year lifespan, gearboxes often fail within 5 years, necessitating replacements. A linked paper discusses various issues related to wind turbine gearboxes. The conversation emphasizes the complexity of selecting the right gearbox without detailed requirements.

TL;DR
This post to share with you how to select the gearbox from market and what are the most important parameters to do that

Please your support to can find this gearbox

What research have you done so far? What have you found out?
 
What are your requirements? You mention RPM. What about power? lifetime? cost? weight? size? efficiency? Your question is so open, we can't provide specific answers.

This paper discusses many of the problems with such gearboxes.

The typical design lifetime of a utility wind turbine is 20 years, but the gearboxes, which convert the rotor blades rotational speed of between 5 and 22 revolutions per minute (rpm) to the generator-required rotational speed of around 1,000 to 1,600 rpm, are observed to commonly fail within an operational period of 5 years, and require replacement.

Thread 'UV filter for home central heating?'

Had my central air system checked when it sortta wasn't working. I guess I hadn't replaced the filter. Guy suggested I might want to get a UV filter accessory. He said it would "kill bugs and particulates". I know UV can kill the former, not sure how he thinks it's gonna murder the latter. Now I'm finding out there's more than one type of UV filter: one for the air flow and one for the coil. He was suggesting we might get one for the air flow, but now we'll have to change the bulb...
