다국어 초록 (Multilingual Abstract)

The reducer is a device that amplifies the force by lowering the speed of the input part when the load of the operating part is large. In order to optimize the design of the reducer, it is important to make the reducer gear lighter and smaller. For this purpose, it is necessary to accurately predict and analyze the distribution of the load acting on the gear. However, the existing research about analysis of the load distribution of gears was mostly based on only gears. This is problem because misalignment of gears is not properly reflected in the analysis. The misalignment is a phenomenon in which gears cannot be properly engaged due to external and complex influences of components such as shafts, bearings, and housings other than gears. This causes a reduction in the life of gears and noise, the damage of the teeth is also. Because of this problem, it is very important to perform the load distribution analysis considering the influence of misalignment in the optimum design of the reducer. Therefore, in this study, I analyzed how the load distribution of the gears is by taking into account not only the gears but also the axes of the gears. The gears and axes are modeled and the meshes are divided appropriately so that detailed analysis is carried out and the distribution of the maximum load applied to the gears is analyzed by setting analytical boundary conditions for static conditions. As a result of the analysis, I could see the unbalance of the load due to the misalignment of the gear, and conclude the analysis considering the gear axis as well as the gear is meaningful. It can be seen from this point of view that a systematic approach such as gear shafts, bearings, and housings, rather than the sides of the components, is essential for accurately analyzing load bias due to misalignment of gears.
