Building the sprocket

Building the sprocket

- Next we will model a chain sprocket. Now I will not be going into the technicalities of sprocket sizing or correct chain selections, et cetera, since our design is only conceptual. The tooth profile I use is also not to any specification and completely sketched to what looked good to me at the time. Now go ahead and open part 0207 Sprocket from the Chapter Two lesson files. I've already added a sketch with the necessary entities. The circles represent the chain and the link rollers. And the profile between the two will be used for the sprocket tooth. Our goal is to only have to provide the amount of teeth we want on our sprocket according to a specific chain pitch, and have the sprocket outside diameter adjust automatically. Now this will allow us to use a single model to easily create configurations for different sprocket sizes and designs. Now we can easily achieve this with equations, which we have used before. I have two variables set: one chain pitch and number of teeth. Now I…
