Book Description
A numerical procedure for evaluating and monitoring contact stresses in meshing gear teeth is discussed. The procedure is intended to extend the range of applicability and to improve the accuracy of gear contact stress analysis. The procedure is based upon fundamental solution from the theory of elasticity. It is an iterative numerical procedure. The method is believed to have distinct advantages over the classical Hertz method, the finite-element method, and over existing approaches with the boundary element method. Unlike many classical contact stress analyses, friction effects and sliding are included. Slipping and sticking in the contact region are studied. Several examples are discussed. The results are in agreement with classical results. Applications are presented for spur gears. Somprakit, Paisan and Huston, Ronald L.

Book Description
This study applied the Numerical Method Model to determine a characteristic for system gear. The most critical components in power transmission system are gearing system because in automotive industry gearing is commonly used in machines. In this study, Finite Element Method was used to analyze gears system. A metal-type material that was used to analyze was two different materials. The first one is gray cast iron because this metal is widely used in industry and the second one is steel 4130 or alloy steel that to know either this material suitable using in gearbox. Gear will be study in static structure condition to determine a stress, strain and also displacement to know which gear got maximum impact for every components gear system. For this analysis used the gearing in gearbox system, with different size, weight, and shape. Before analysis is done, a gear system was modeled/designed using the SolidWork software. Every each gear are draw only using SolidWork because SolidWork were very flexible to design anything with any direction (3D). This software was used for determine a stress, strain, and displacement in the meshing model condition. From the FEM analysis result at every component gear, it was found at gear six for Driven and at gear one for Driver that got highest value stress, strain and displacement at 1000 rpm. So different materials maximum impact at same place for stress, strain and displacement but their value is not same, for gray cast iron the maximum stress is 4397.26 N/mm (driven) and 6471.42 N/mm (driver). For alloy steel the maximum stress is 4329.62 N/mm (driven) and 4735.89 N/mm2 (driver). Conclusion is if the speed in term revolution per minute is low, so the stress, strain and also displacement value will be high for static studies.

Book Description
This paper presents procedures for designing compact spur gear sets with the objective of minimizing the gear size. The allowable tooth stress and dynamic response are incorporated in the process to obtain a feasible design region. Various dynamic rating factors were investigated and evaluated. The constraints of contact stress limits and involute interference combined with the tooth bending strength provide the main criteria for this investigation. A three-dimensional design space involving the gear size, diametral pitch, and operating speed was developed to illustrate the optimal design of spur gear pairs. The study performed here indicates that as gears operate over a range of speeds, variations in the dynamic response change the required gear size in a trend that parallels the dynamic factor. The dynamic factors are strongly affected by the system natural frequencies. The peak values of the dynamic factor within the operating speed range significantly influence the optimal gear designs. The refined dynamic factor introduced in this study yields more compact designs than AGMA dynamic factors.
