The pitch is 1 inch, thenumber of teeth in the large gear is 36, and in the smallone 18. The pitch diameter of the large wheel is found byformula 1 to be d — —- = inches, nearlv. The pitch diameter of the small gear = 1 X 18 = inches, nearly. The diameter of the describing circle is found by formula4 to be d = ., ^ ,, , = For all practical purposes, the diameter of the describingcircle may be taken to the nearest 16th of an inch.
