The dynamic analysis of the gears has become important part due to the pressing need of high speed and heavy load carrying machinery. A high contact ratio spur gear pair reduces the variation of tooth stiffness and thus to reduce vibration and noise. It also improves structural efficiency, reliability and power to weight ratio. With increased requirements of high speed, heavy load and light weight in gear design, the dynamic load is required to determine among two or three pairs in contact. In this work, an experimental discussed for calculation of the equivalent contact stress sharing among meshing teeth pairs with different contact ratio. Also, calculation of maximum deformation during different contact ratio in mesh cycle of the spur gear. Variable shear stress which are required for dynamic load calculations are found using numerical methods. This information may be useful in further analysis of High Contact Ratio Spur Gear drives.
