They are all imperial gears 14-1/2 deg pressure angle and assorted DP depending upon the particular gear. Did you have a question about a particular gear? - Terry
Well.......all of them really!
I guessed they were 14 1/2 gears from the shape of the teeth
I was looking at the teeth you cut into your crankshaft and was wondering what size the gear is. I assumed 16 teeth on a 0.5" PCD since this a standard regularly available gear size (32 DP) and with the addendum added, the OD of the gear would be just slightly smaller than your main bearing journal. This is all assumption on my part however!
I've designed a set of gear templates in Pro/Engineer CAD software and I can create any spur or helical gear in any configuration I like in a matter of seconds. I have input paramaters for PCD, number of teeth, pressure angle and helix angle (which is set to zero for straight cut teeth).
