    Calculation
In summary, the person is looking for a gearbox similar to the one used in wind turbines, with an input RPM of 1 and output RPM of 1500. They are asking for support in finding this gearbox and have not specified any other requirements such as power, lifetime, cost, weight, size, or efficiency. The paper mentioned discusses the problems with such gearboxes and notes that they typically have a design lifetime of 20 years but often fail within 5 years of operation.

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

I want to buy a gearbox very near of the one used in the wind turbine

I need the input RPM to be 1 rpm and the output to be 1500 rpm

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.

Related to Gearbox Selection and Calculation

1. What is the purpose of selecting and calculating a gearbox?

The purpose of selecting and calculating a gearbox is to determine the appropriate type and size of gearbox needed for a specific application. This involves considering factors such as torque, speed, and power requirements, as well as the type of load and operating conditions.

2. How do you calculate the gear ratio for a gearbox?

The gear ratio for a gearbox can be calculated by dividing the number of teeth on the driven gear by the number of teeth on the driving gear. This ratio determines the speed and torque output of the gearbox.

3. What factors should be considered when selecting a gearbox?

When selecting a gearbox, factors such as torque and speed requirements, operating conditions, efficiency, and cost should be considered. It is also important to ensure that the gearbox is compatible with the other components in the system.

4. What are the different types of gearboxes available?

There are several types of gearboxes available, including spur, helical, bevel, worm, and planetary gearboxes. Each type has its own advantages and disadvantages, and the selection should be based on the specific application and requirements.

5. How do you ensure the reliability and longevity of a gearbox?

To ensure the reliability and longevity of a gearbox, proper maintenance and lubrication are essential. It is also important to select a high-quality gearbox from a reputable manufacturer and to consider factors such as load distribution and alignment during installation.
