What kind of glue can be used to join flat drive belt and v-belt?
For my special project I need to join flat drive belt with a v-belt (the wider part of it's profile to be precise). Due to the nature of their application such combined part will be rotating with most of the power transfered via the v-belt (it is supposed to be a diy tank track). The joint must be able to bend as the whole contraption will be stretched between two 20cm diameter wheels. I plan to reinforce it with screws or rivets.
Could you please advise what kind of glue can do the job?
I'd use Shoe Goo ... it dries rubbery and flexible.
Another alternative would be contact cemement (I use DAP, personally, do not get the non-flamable one that cleans up with water), but it's much harder to work with in general. And they're serious about using it outside -- the fumes are very strong.
And my last choice would be basic rubber cement ... the bond's not great, but if you're reinforcing it, it might be okay. (just don't get the 'repositionable' stuff)
If you're going to be rolling a v-belt around two rollers, I don't think you can glue a continuous flat belt to it and have it stick. Unless the flat belt is very flexible along the length of it (which is usually exactly what it's designed NOT to do), you might have a problem with the belts flexing differently. If you glue the belts while flat, they won't curve, and if you glue them curved, they'll want to stay curved.
If you get a flat belt and turn it inside out, then you'll be gluing the reinforced tensioning part of the belts together, and it might work. In that case, I'd probably just use contact cement like Joe and Scott say.
This late, is probably too much trouble, and might not work anyway. Well, I won't let that stop me!
Playing off of @Steve Armstrong's thought that the continuous flat belt probably would stick successfully and given that your application is for a tracked vehicle, how about an approach like this:
Rather than gluing the flat belt to the v-belt, what if you cut the flat belt (or some other material) into chunks, each of which is glued (or otherwise attached) to the flat belt. So, the "outer" surface of the track is not a continous flat belt, but is segmented.
You might be able to avoid some of the inherent shear that is likely to occur between the continuous flat belt and the v-belt as the "track" rolls around the two (or whatever number you have) rollers.
