“…Some successful attempts are reported for further optimization of placatory gearboxes those are mainly aimed at cost reduction by reducing weight without compromising the effectiveness. S B Nandeppagoudar et al [4] founded and demonstrated the optimization case of a 3-stage planetary gear box for machine tool application. The improvement mainly seen in terms of reducing the number of stages and achieving high reduction ratio while also addressing space and load constraints.…”

Planet carriers are one of the important and heavy components in planetary gearboxes. Planet carriers of heavy gearboxes used for large applications are not produced in numbers. However, the increasing cost pressures has forced designers to apply weight reduction and optimization methods for components like these as a one-time obligatory exercise. In the presented case, a candidate planet carrier used in the gearbox of a sugar mill is considered for weight reduction exercise without compromising its strength. 3D CAD model of the given planet carrier is prepared and analyzed to understand the operating stresses. The knowledge of predictable stress values at various locations are used to guide the optimization. Numerical simulations are carried out with AI based Whale optimization algorithm for optimization. Obtained dimensions of optimized planet carriers are verified by the stress analysis again. The results predicted that a weight reduction of 8% can be possible with the optimized design without compromising the design constraints. The work demonstrates that a relatively simple whale optimization algorithm can be used to optimize weight for many such heavy components

“…Additionally, multiple shafting, high power efficiency, a significant volume reduction, and pure torsional reactions are all accomplished with planetary gears. With more planets in the system, the load limit and torque density increase, which is another feature of the planetary gearbox configuration [4].…”

“…Vijayarangan and Ganesan [8] studied the dynamic analysis of stresses in a spur gear under a moving load and three-dimensional finite element impact conditions. Gawande et al [9], designed by classical calculations the pinion gear using the given data and modeled the gear in PRO-E (wildfire4.0), which is an excellent CAD software, then transferred to IGES format and exported the model to the software analysis tool ANSYS 13.0. and studied the results obtained for stresses and strains.…”

In this work the 3D model of the Torsen differential assembly was designed using Autodesk Inventor 2023 and finite element analysis is performed using Nastran software by applying restrictions, contact conditions and loads conditions. The materials taken for static analysis are chosen in concordance with the literature data. Maximum Von Mises stress values were obtained at the base of the gear tooth. After running the fatigue analysis, the tendency to reduce the life of the gear was observed, by breaking the teeth due to fatigue, which occurs due to repeated bending of the tooth, which results in fatigue cracks and finally tooth breakage

“…ey have presented another work about the minimization of the weight and the center distance of one pair of spur gears [20]. Nandeppagoudar et al [21] redesigned the three stages of planetary gearbox by reducing one stage which will be suitable for machine tool application where the space and load constrains is the prime objectives. Analytical and numerical results are compared to see the effectiveness of modified planetary gearbox.…”

The determination of optimal design of the planetary gear train with a lightweight, a short center distance, and a high efficiency is an important issue in the preliminary design of power transmission systems. Conventional and traditional methods have been widely used in optimization. They are deterministic and limited to solve some mechanical problems with several variables and constraints. Therefore, some optimization methods have been developed, such as the nonconventional method, the genetic algorithm (GA). This paper describes a multiobjective optimization for the epicyclical gear train system using the GA. It is aimed to obtain the optimal dimensions for epicyclical gear components like a module, number of teeth, the tooth width, the shaft diameter of the gears, and a performed efficiency under the variation of operating mode of PGT system. The problem is formulated under the satisfaction of assembly and balance constraints, bending strength, contact strength of teeth, and other dimension conditions. The mathematical model and all steps of the GA are presented in detail.
