This paper deals with the effect of deformation on
contact ratio and stress behavior of plastic spur gear. It is shown
that when one tooth of gear comes into contact with pinion tooth
it gets some amount of deformation and due to thisdeformation,
the behavior of second tooth coming in contact changes affecting
the contact ratio. The contact ratio in actual practice differs from
the theoretical results. For getting deformation and stresses on
gear tooth, FEA is done. Results obtained Indicate that in actual
practice contact ratio is higher as compared to the theoretical
results in case of plastic gears.
