Arajpure (2014), havestudied and shown that Nylon66 is better option against theissues due to acetyl gear because of superior properties ofNylon.Cheng, Y.
They carriedout test on both the gear system and observed that for bothIJERTV5IS100388the asymmetric tooth form and optimized tooth form hashigher bending strength when compared to baseline designs.Pushpendra Kumar Mishra (2003), have identified thatbending strength and surface strength are the key factorswhich are involved in failure of the gear tooth of a gear sets.Also they identified & studied that various researchers haveused different techniques for the optimization & calculationof stresses which are contributing in gear design.Ashish N. Both these gears wererepresentative of helicopter main gear drives. Brown (2011), have done research to differentiatethe bending and contact stresses between asymmetric andsymmetric involute gear tooth. Also mentionedthat for the failure of gear teeth, root bending stress playsmajor role in fatigue fracture while contact stresses areresponsible for pitting failure of contact surface.F.W. (2013), has done co relation betweenstatistical calculation of bending stress by Lewis formulaagainst the FEA by Ansys FEA software.
(2016), they haveestablished the co-relation between AGMA equation andFEA Software Ansys for calculating bending stresses andcontact stresses.A.Y. The results obtained from AltairHYPERWORK OptiStuct, are compared to investigate thepossibilities of using Nylon as an alternative material for gearsagainst traditional as steel in power and/or motion transmissionsector.Keywords- Computer Aided Design Finite Element Analysis Helical Gears, Hyper Mesh, HYPERWORKS, OptiStruct StainlessSteelI.INTRODUCTIONJitendra Singh Chauhan et al. A pair of standard helical gears is used and analysis isperformed on by FEA Software Altair HYPERWORKOptiStruct solver using the following two conditions for thesame power output (i) gear pair made of nylon and (ii) otherpair made of stainless steel. To determine the contact stressesbetween two mating gears, the analysis is carried out on the twogears. This paper also considers the study of contact stressesinduced between two gears. Theanalytical investigations are carried out by varying the load ongear. To estimate & identify the various stressesand other important parameters of helical gears, a threedimensional solid model of set of gears is generated using theComputer Aided Design Software Pro/Engineer, which iscurrently being known as a strong tool for solid modeling. In this paper the major focus is onstudying stresses and pressure distribution using analytical andfinite element analysis for the characteristics of an involutehelical gear system. Thus, to reduce the failure of gear & foroptimization of gear design analysis of stresses resulted intomajor are of interest.
