Motors and gears (how to get starting)
Hi guys
I want to start experimenting with motors and gears. (Small scale. Maybe half tbe size of my old RC car motor or smaller) Unfortunately I live on a small island :-) and I think I may find it difficult to get the parts. I understand that I need a motor with a pinion gear and then other gears. Unfortunately it seems like my favourite webmarts don't stock these together: www.radionics.ie www.maplin.co.uk They almost always have motors WITHOUT pinion. And they don't seem to stock pinions on their own. This results in a few questions... Where can I buy pinions? How do I know it will fit on my motor? I remember from my RC days that the pinion had a little screw to fix it to the axle. Is that what I should look for? Or should I just get a pinion that fits very tight on the axle of the motor? Why on so many technical diagrams don't they show you the diameter of the hole through the gear? I can only guess that it's a thrid of the hub but I would have thought that that would be an important property to document. I did notice that when searching for gears these webistes show something that looks like a motor with a gearbox added to it but even then it didn't have a pinion. I must be missing something. Please enlighten me, and for a bonus point, I'll be VERY grateful is someone can show me these parts on the websites I mentioned. Thanks! |

See: http://www.sdp-si.com & order their catalog set. It comes with loads of engineering data on power transmission systems of all kinds. They'll send it free (maybe not, if you're isolated/overseas) & it's a valuable resource, even if you never buy a thing from them. Nothing about motors, though. I'd go to the source(s) - the manufacturer(s) - for that info. JM |

Computer printers have gears . You would have to order the motors in .
