- # N - Number of Teeth in the gear (Input in the dialog box)
- # DP - Diametral Pitch of the gear (Input in the dialog box)
- # P - Pitch diameter of the gear
- # A - Addendum of the gear. Outside diameter = P + 2 * A
- # C - Clearance
- # B - Base radius of the gear
- #
- # Note:1. The range on the diametral pitch is inclusive of the lower limit
- # and exclusive of the upper limit.
- # 2. The variable are calculated in the order P, A, C, and B. Hence
- # make sure that if a variable formulae depends on any of the others
- # they are already calculated.
