Alright, here it is. The necessary distance between the teeth must be equal to 2(pi)(radius of wheel from the center to the top of a tooth)/(number of teeth).
So, for an example I'll just say the chain distance I'm talking about is d and the radius from the center of the sprocket to the outside of a tooth is r.
For a ten tooth sprocket, you'd start with d = 2(3.14)r/10. Since you know what the distance is and you need to find what the radius needs to be, you need to isolate r on one side of the equation.
d x 10/(2 x 3.14) = 1.59 d = r
So for a 10 tooth sprocket, the radius from the center to the outside of a tooth needs to be 1.59 times the distance between the corresponding parts of each link.
Did that make sense? I can elaborate if necessary. Hope that helps.
Thanks, I'll see if I can come up with a working model. I think my chain might be part of the problem; it isn't the best.
@@MakerBrain Awesome, I hope it works!
A proper sprocket should have depth and slopes, not be rigid and shallow. The reason for this is that it will correct itself if it doesn't fall perfectly into place.
Thanks. I want to start working on a completely new chain design that will work well with sprockets based on the amazing recommendations from this video.
Lemme see if I can figure out the math.
what's the distance between the chain links? like how far is it from the is it side of one link to the left side of the next link when they're all put together?
Thanks for your help. It has been a long time since I worked on this project but when/if I make a revision I will be sure to use the equation. The current model needs an over hall to get it to work.
Have a blessed day!
