From the results in structural analysis, the properties of the treated EN8 & EN19 Steels are enhanced than the untreated EN8 & EN19 Steels. It is designed using CATIA software and imported the model to ANSYS work bench software. The sample pieces of EN8 & EN19 carbon steel components are placed in a specially constructed tank containing Cryogenic solution as Liquid Nitrogen (Refrigerant) and at the temperature of around 196°c (77k) and treated for for 24 hours. The process involved in the Cryogenic Technique is deep cryogenic process. This technique increases the wear properties and decreases the machining time of the tool. The brainstormed ideas to alternate tool material properties by using a method called Cryogenic Technique. To increase the ability of the tool, the best way is to increase the hardness of the tool. In general high speed steel is used as a cutting tool for its better quality and reliability at lower rates while compared with other cutting tools. As the result, the proposed modeling was in a good agreement to the analytical model and reliable to conduct the spur gear time-varying strength analysis. The critical location (CL) for each strength property was also investigated. The objective was to conduct the analysis of time-varying strength of the spur gear system and compare to the analytical equations. Therefore, the main aim of this study is to develop a new simple quasi-static modeling based on ANSYS Workbench. However, the complexities of the gear tooth may cause the modeling to imperfect zone of assumption. Both solution are capable to offer several output results and interpretation. Two different modeling approach commonly used was based on static or dynamics application to the finite-element solution. With the advent of computerization era many researchers turned to finite-element modeling as the important tool in gearing studies. Two components of spur gear time-varying strength known as tooth surface contact stress (TSCS) and tooth root bending stress (TRBS) can be evaluated using an analytical or finite-element method (FEM). Measurement of gear tooth strength is important procedures in a preliminaries gear design. Finally, conclusions are drawn based on the theoretical and analytical results. A true assessment of the contact region is made so as to predict the behavior at extreme conditions. Results such as maximum contact pressure, maximum shear stress, and maximum principal stress are determined. The finite element analysis software ANSYS Workbench was used for this purpose. In the development phase, the contact stress analysis is carried out. With CATIA, the parametric modeling at the interface of the roller and pallet is carried out. A contact patch is generated at this line of contact. High stresses are generated in this case as the total load acts through this line of contact. The pallet along with the load rolls over the rollers making a line contact in between. In this study, Roller conveyor conveying huge loads over varying lengths is considered. The roller bearing assembly and spur gear pair assembly is an example where the assembly undergoes fatigue failure due to contact stresses. In many cases, the resultant stresses are not of design significance, but in some cases failure can occur. The application of Hertizian contact stress equations can estimate maximum stress produced and ways to ease the stresses can be sought. If not considered and addressed adequately, these stresses can cause serious flaws within the mechanical design and the end product may fail to qualify. In context to this, one also needs to address stress issues at the contact regions between any two elements stress is induced when a load is applied to two elastic solids in contact. In general, Roller Conveyors are designed with a set of elements to reduce cost, ease of assembly and manufacturability etc.
