We’ve struggled over the years to properly tension our chains, belts, and cables. I’m sure it was very entertaining for those not on our alliance when we used oversized, free-spinning sprockets between the lengths to take up the slack. They went flying in all directions upon each defensive impact.
My personal query is regarding longer runs where the sprocket or motor axles cannot sustain massive tension loads. I’m thinking that increasing the angle a chain/belt wraps around the sprocket reduces the required tension or stress.
I’m sure there are different tensioning challenges others will find informative and useful.
I am hoping some of you may have advice and examples of robust, clever, or compact solutions for long or irregular conditions where Center-to-Center calculation is not enough. When is a spring-loaded tensioner appropriate and when should a solid one be used?
One example by @gear caught my eye and triggered my post. This tensioner appears to be robustly mounted on sheet metal. I’m hoping he will describe the sliding block and if the sprocket axle and tension screw may intersect.
