Comparision Of High Contact Ratio And Low Contact Ratio Gears

Abstract

In this paper, comparison of high contact ratio gears and low contact ratio gears has been done for the same load. we have considered the bending strength, shearing at contact region, normal stress and some contact parameters like contact pressure, penetration and contact stiffness to compare HCR gears and LCR gears. in the results we have found that HCR gears r deforming less when compared to the later type for the same load transmitted. bending strength in HCR gear set less when compared to the later one because of the load distribution among the teeth.
