Abstract—A gear is a rotating machine part having cut tooth, which mesh with another toothed part in order to transmit torque. Gears are mainly type like spur gears, helical gears, double helical gears, bevel gears, crown gears, hypoid gears, worm gears, rack and pinion, epicyclic gears etc. The application of these gears fled from tiny wrist watches to huge machinery equipment gears from vital elements of mechanism in many machines such as automobile, aerospace industry, rolling mills, hoisting and transmitting machinery, marine engines, and the like. Parallel and co-planer shaft connected by gears are known as spur gear. Spur gear have straight tooth and are parallel to the axis of the wheel. Spur gears are most common type of gears. A pair of spur gear tooth in action is generally subjected to two types of cyclic stress: contact stress and bending stress including bending fatigue. Both stress may not attain their maximum values at the same point of contact fatigue. These types of failure can be minimized by analysis of the problem during the design stage and creating proper tooth surface profile with proper manufacturing methods. In this paper using ansys work bench software, bending stress, contact stress and static load on the tooth of spur gear drive is found
