(...) I've not made very much GBC before but this was such a nice idea that I thought I'd have a go Brian: (URL) I used 36 tracks with pins on alternate ones to give a maximum 4 balls/second output. This can be reduced easily to the standard 1 (...) (18 years ago, 21-Mar-07, to lugnet.technic, lugnet.loc.uk, lugnet.announce.moc, FTX) !

(...) Hi Ian, Nice MOC! I agree with you: integrating a Manas is not a simple matter. Here is an idea for you: use the spare function in the trailer's Manas to raise / lower a pair of landing legs (See picture of the real thing here: (URL) that (...) (18 years ago, 21-Mar-07, to lugnet.technic)

I think one way to do this uses a differential (URL) and a pole reverser (URL). I don't have a picture to hand but the idea is simple. One side of the differential is connected to the low torque "input axle". The differential housing is connected to (...) (18 years ago, 21-Mar-07, to lugnet.technic, lugnet.robotics)

(...) A torque amplifier is EXACTLY what I need; thank you! Now I just need to figureout how to build one. Google has a few pix, two lego ones actually. I hope this will get me where I need to go! Thanks for the help, Rafe (18 years ago, 21-Mar-07, to lugnet.technic, lugnet.robotics)

More information about your application would be helpful. The first thought that jumps to mind is "Use a more powerful motor. Duh!". So there must be something that I am missing. There must be some reason you need to use the puny motor. Maybe you (...) (18 years ago, 20-Mar-07, to lugnet.technic, lugnet.robotics)

| | Boosting power in a gear train

I have a gear train that is driven by a very weak input, very small torque. There are some places in the gear train where I have some worm gears driving some 'regualr' gears. As I go along the gear train, I boost the output as much as I can with (...) (18 years ago, 20-Mar-07, to lugnet.technic, lugnet.robotics)

Timothy is right about the mechanical advantage, and explained it very well! One more thing to remember is that since the worm gear acts as a "lock" for the other gear, you don't want to put too much torque on the other gear. You can either rip the (...) (18 years ago, 14-Mar-07, to lugnet.technic)

(...) Basically, a worm gear has one tooth. So using that with a 40-tooth gear reduces the rotational speed by a factor of 40, and increases the strength by the same amount. Also, worm gears can drive a gear, but can't be driven by that gear, so (...) (18 years ago, 14-Mar-07, to lugnet.technic)
