3 Answers

create a series of extrusions, 1st one being the edge of the sprocket, 2nd one being the teeth, 3rd one being the other side. build it from the side where it looks like an "O".

Hi Seleshi,
why not try to use the toolbox content ? Open a new assembly document, open / activate toolbox and look for this type of part by browsing folders. Insert the part into assembly, adjust parameters (theets number ...), validate and save document as a part file (.sldprt) = it's done.
Hope this will match your request.
