help with go kart belt drive Anonymous 2016-03-13 17:10:10 Post No. 961213 [Report]

So I want to build a go kart, and I'm using a 30,0000 rpm brushless inrunner. I think I want to go with a timing belt drive system. The motor can output 1.5 kW, and I need a belt that can withstand both the high rpm and power. What sort of belts and pulleys should I use? The motor has a 8mm d bore shaft and I need a 1:5 ratio. I also will mount a #25 chain sprocket to the output pulley, I don't know how I could do that either. If someone could help point me in the right direction that would be lovely, I'm just struggling to know what to Google and how to understand belt specifications.

What you are looking for is called a "toothed belt"
Check for electric scooter parts and you should find just what you need.

For high output, is there any option of using a chain drive?

Not really, given the RPM.

You can totally use a chain, do your research and find suitable chain/sprockets/attachment methods, others have done this.

You wouldn't be turning the chain at 30k rpm anyways given any sprocket you can use, slippage would be a huge problem with any significant amount of weight with that sort of rpm/power.

I would recommend a gear house before the chain/belt as high transfer ratios are inefficient due to the large tourqe difference.
Also 30K RPM wold need quite a high gear ratio to give sufficient torque at low speed..

Revers calculate the gear ratio from desired max speed, wheel circumference and motor max RPM*0.8
