Sprocket Help Please

[Randy727]

I had a customer bring me a chain yesterday and wanted a sprocket made for it. I thought I had it figured out and laser cut a portion of it. Sadly I found out that I was wrong. I measured the chain, and drew two of the teeth of the sprocket. What I can not figure out is how do you do a radial pattern of something so that is is equal on all of the teeth. From what I can see it just gives you a count with equal spacing but does not include the original one that you are applying the pattern to. That makes the last space different than the rest of them, and they all seem to get a little worse as they go around the chain. I hope that this makes sense to someone. I have never been approched to do a sprocket, and am just not familiar with the terminology. I have attatched what I started with. If anyone can help me I would greatly appreciatte it.

The SW toolbox has a ton of different sprockets, including chain sprockets, that you can configure about any way under the sun. No sketching needed!

Go to the toolbox, go to ANSI Inch, then Power Transmission, then Chain Sprockets, right click the chain sprocket type you want to create, and select create part.

It might take a bit of testing to figure out what the various parameters mean, but it's a much faster option than trying to draw gears or sprockets.

As for your original problem, you should know how many teeth the sprocket is to have. Divide 360 (degrees) by the number of teeth, and that will tell you the width of each tooth relative to the circumference of the entire circle.

Hope either of these suggestions help!

Thanks alot for the info CarbonKevin. I was able to modify one of the sprockets in the toolbox to work. Was much easier than what I was trying to do. Thanks a bunch.
