How does it work?

The Gearbox Builder was built with simplicity in mind. It asks simple questions in a logical order and then uses those answers to do all the complicated algorthims to determine what parts are needed to build the gearbox that fits your criteria.

What is your Input?

What is your desired output?

Now that we know our input, we need to know our output. The two main criteria are:

Ratio (Output RPM)

How much you want to reduce your RPM by. Ratio is measured between Input RPM and desired output RPM

How long do you need to run the motor for

How is the motor mounted?

Now that we know our input and output. How does it fit? How is it going to be mounted?

Depending on the configration up to this point, the options would vary based on the frame of the motor and gearbox. Pick the mounting option that best suits your needs.
