How much can the minimum diameter of a 2 modulus gear be designed?
Of course, if the positive displacement can choose small tooth number 1 to 2 teeth, smaller diameter, not small too much.
17 * 2=34, the addendum circle diameter is 38, so the modulus is 2, the minimum gear diameter is 38
The minimum number of teeth of the standard spur gear is 17 teeth, and the diameter of the gear indexing circle is equal to the number of teeth multiplied by the modulus,
