Gears are essential and useful elements which power is transmitted from a source to a driven equipment. Therefore, it is very important to design gears correctly. Two important points in the gear design procedures are capacities of the gears's bending strength and pitting resistance. This paper deals with two subjects about spur and helical gears : analyzing for strength and wear capacities, and design of face width. Also, this paper proposes the analytical program which is developed for computer aided design and analysis This program is based on the American Gear Manufactures Association(AGMA) Standards.
