Min no of teeth =(2*addenda)/sin^2¢
For 14.5 degree full depth=32
For 20 degree full depth=18
For 20 degree stub =14

The minimum number of teeth on the pinion in order to avoid interference for 14.50 full depth involute are 32 and for 200 full depth involute teeth are 18. Explanation: Interference occurs when the number of teeth on the smaller of the two meshing gears is less than a required minimum.
