When you have the motor and battery and you define for yourself what 'medium speed' is, you can go to the calculations.torqueboards wrote:... What would be the best gearing for medium speed?
For the belt, 10/50 would be better, but you should go for 6/30 since it's lighter and smaller. The belt can handle it Actually they're both bad choices though! You want the 'smallest common multiple" of the teeth to be AS LARGE AS POSSIBLE (http://www.mathsisfun.com/least-common- ... -tool.html). I can explain this in detail, but summarized it means that the wear will be equal on all parts of the belt and gears. This means 9/50 is better and 11/50 is even better!torqueboards wrote:What would be better 10T/50T or 6T/30T?
torqueboards wrote:Awesome. That clears it all up. Thanks again Murfix! The descriptions helped.
Maybe, you can help with this one too. How do I calculate my average distance on my battery?
PracticalProjects wrote:great response murfix! That definitely should have answered your question some people like to have the most teeth that will fit on there wheel because they believe that it is better and stronger this way as there is more belt in contact with the cog. I'm not exactly sure if this helps much but it is certainly a logical view.
