<p>You can't do this with the gears you've listed, but I'm not sure that you've listed the proper gears. I don’t believe that 32 or 64 tooth gears exist. I at least don't have any.</p>

<p>You can do this by combining common 8, 16, and 24 tooth gears. The following gives 3:1 × 2:1 × 2:1 × 2:1 = 24:1.</p>

<p>You cannot increase the output speed by 24 times using a classical gear system, and the gear teeth you specified, because 24 is not a product you can make from 2, 4, 8, 0.5, 0.25, 0.125.</p>

<p>You CAN, however make a CVT, which takes two input speeds and divides them to give an output.</p>

This is binary arithmetic at heart, you have powers of two tooth counts in your question (but you can't get those from Lego) and since 24 isn't a power of two it's going to take a non-trivial mechanism to get it. You could use a brick-built differential, for example... except where do the gears come from.

# How do I increase axle speed using gears

(Asked by: username_0 on 2016-10-19)

How do I increase speed of my output axle 24 times using 8, 16, 32, and 64 tooth gears using LEGO Mindstorms components? I checked [Sariel's website](http://sariel.pl/) but it was no help.

You can't do this with the gears you've listed, but I'm not sure that you've listed the proper gears. I don’t believe that 32 or 64 tooth gears exist. I at least don't have any.

You can do this by combining common 8, 16, and 24 tooth gears. The following gives 3:1 × 2:1 × 2:1 × 2:1 = 24:1.

jncration is correct.
