Hello all, I have two rollers that will be rotated which will in turn rotate another tube on top of them. The connection will be made with a drive chain between the motor sprocket and the roller sprocket(s). My question is, would it be better to connect the chain to one roller, or to both? I'd think that since the work to be done is the same in both cases (rotating the tube), there shouldn't be any difference in terms of power consumption and it would provide extra stability. May there be any other thing to consider? Oh wait, I actually found a similar setup, though I am not sure how the chain system at the beginning works. It looks like there are two sprockets on the motor shaft and two different chains are used, but can't be sure. My main problem is that what I've learned in school and all the information I can find about chains are for two sprockets. I made all the necessary calculations for a two sprocket setup but don't know what would happen if three sprockets are used. Thank you for any help.
