Lego gear calculator

[Erik Leppen]

I actually made this in 2007 but I never got to adding a topic to Eurobricks. There must be Technic builders around who could use this, other than just me. So what does this little program do?

If you give it a gear ratio, like 1 : 1.4527, it tries to find a gear combination as close as possible to that. Unfortunately sometimes it generates a combination that is hardly usable (e.g. using a 14:36 combination) but you might find combinations you didn't think of. I made this for myself initially, for creating a realistic steering mechanism for multi-axle cranes. Here, the different axles need just the right speed ratio to look realistic and roll smoothly. But I bet people could use this for different purposes. And if not, it can also be just fun to play with (although there's not that much you can do).

Note: it's finished. I'm not working on it anymore. I'm just putting it here so people can use it.

Oh, by the way. Don't set the amount of transfers to 4 and all gear types to Yes, or it will take ages. The program uses a brute force approach and isn't exactly fast... :P

Thanks. I'll try your gear calculator. I'll be working on a fully remote 8265, I would like a super low gear combo for the driving wheels to get that scaled down realistic 20 km/h pace of the actual vehicle and some serious shoving torque, unlike some 'turbocharged' pace of the 8265 I saw on Youtube

I agree and some on YouTube are way to fast at driving and it's not controllable at all at that speed,the 8265 is still available in Ireland but I think I prefer the 8043-B model and works out cheaper.

that could be handy for many people ,but i like the tryed and trusted way as i dont like working with all that math stuff

if it works good ,if not than try something differant
