Utilizing pre-made gears in a gearbox

[avanboekel]

There are gear models available on Vex pro's website. They have a wide variety of gears to choose from.

There are motions constraint available for use in inventor. I don't remember exactly how to use it, but I think its in the same constraint window that you would use for a mate or flush constraint.

You can use a gear distance calculator to get the distance between gears right. They are all over the place online.

Hope this helps, let me know if you have any other questions!
