Need advice! Over the years, we used a takeup sprocket, them a take-up drum. Some are moving back to the sprocket, some to the drum. What are the old-timers thinking in terms of the sprocket vs drum option? Please respond!
This is pretty right on. The drum has a lot to do with allowing chain some side to side motion and 1/2 the wear that a sprocket puts on the inside of the links. In many cases if there are alignment issues with the chain and it is pushing on one side of the drum, a sprocket will be used to force it to run straighter. This however does not fix the alignment issue.The drum allows some sideways motion of the chain without the strain that would be present from sprocket teeth. I would also say that with the drum there are no teeth to wear on the chain or the teeth themselves.
Our problem is that the chain has to be so tight so it wont fall off of the sprocket then we have to run 120psi on the take up to keep it from jamming the roller raiser. So I guess that is too much for the drums (SOnnys say that it can only handle 70 psi max
