belt drive

Post by 1leonchen » Wed Jan 21, 2015 1:39 am

i am currently working on a conveyor belt for paper handling. i want to get two 1.9 inch diameter by 18 from Granger. i want to drive one of the roolers with a stepper motor. i am planning to get another aurdino, one nema 23 motor, and a grbl shield or a adafruit shield with a gt2 pulley and get a 9 inch gt2 belt. my problem is i need a gear or a belt that i can attach to the 1.9 inch rooler. i looked at other options and didnt find any thing logical. what would u suggest. or can i use a gear that can fit the 1.9 inch shaft and a gear that can fit the nema motor. i would love any random suggestions. please and thanks. :D

They make rollers that are made to be run by eagle belting (round belt). Try looking for that in McMaster Carr.

Recreating this? https://www.youtube.com/watch?v=_oviVoRRQ3g

Put the roller and a pulley on a common shaft so they turn together. In a typical printer, you'll have several rollers across the paper width all on the same shaft, with a gear or pulley turning the whole shaft from one end. I think the type of rollers SmokyRick is suggesting are these: http://www.durabelt.com/lineshaftinfo.php They're simple and easy to implement, and they can slip which limits torque for safety but that might be a bad thing in paper handling.

Stock Drive Products (sdp-si.com) is a good source of gears and pulleys, especially if you're in the US.

i am not recreating the paper plane which is cool. i am making a uv convyer dryer. some thing like a uv dryer unit with a motorised belt. (http://www.intertronics.co.uk/products/dymuvc5.htm)
the dura belt site looks like what i need gonna call them tomorrow. and see what they have that i can use. thanks.

Just FYI, we just got done industrializing one of these at work. Scientists tried to run a normal belt on a UV lamp unit they cobbled together and it didn't end well. The UV killed the belt in no time.

We ended up integrated a larger UV resistant conveyor with their custom design. Make sure you properly shield it, it's like looking at the surface of the sun when that bulb is on.

Edit: just saw you had the metal rollers chosen. Not sure of the power of your UV unit but any metal we ran through ours was very hot 150C after passing through the UV. Metal absorbs very well compared to the plastic belt. Don't know your application just throwing out my 2 cents of what we learned.

thanks for the input. i am running a infrared element. at 250 degrees.
planning to use a fiber glass belt.
and when finished use a custom belt which is Kevlar re enforced.
thanks for the heads up. noted

I've had belt drive on my bike for two years now.
I thought I was logging all my rides, but I seem to have missed ten months out, so all I know is that I have done at least 6400km in that time; 2800km with the Rohloff and 3600km single speed.

I've broken three belts, then yesterday, I stripped a load of teeth off another one.
