“…According to the above settings, the total deformation program, equivalent stress program, and equivalent strain program of the gear train are obtained after transient dynamics analysis of the gear train, as shown in Figures 14-21 [36,37]. Since the maximum strain and stress in the planetary gear train occur in the sun gear, only the stress and strain on the sun gear are analyzed.…”

Since the output torque of the rotary reducer of the ZYL-15000D-kilometer directional drill is proportional to the gear train transmission ratio, the output torque is large enough when the input speed and output speed meet the design goal. This paper selects the method of reducing the transmission ratio to optimize the size parameters of the reducer. MATLAB genetic algorithm is used in the optimization design, and the minimum volume of the rotary part reducer is taken as the objective of optimization design, while the design variables and constraints are determined. The optimal value of design variables was obtained through optimization, and the parameter values of each gear were determined accordingly. Through analysis, the total volume of the optimized gear reducer was reduced by 49.6%. Then, the 3D model of the optimized gear was created, and the analysis of the transient dynamics of the optimized gear was carried out with ANSYS Workbench software. According to the analysis results, the optimized gear met the strength requirements and provided a reference for the subsequent optimization design of other types of gear reducers.

“…Finite Element Analysis (FEA) is a powerful tool for analyzing the behavior of gears and determining their maximum power transfer capacity. FEA enables engineers to model and simulate the complex interactions between gears, spline bushes, shafts, and the interference fit (CHAVADAKI et al, 2021). By applying appropriate material properties, loading conditions, and boundary constraints, FEA can provide detailed insights into stress distribution, deformation, and potential failure modes, helping identify the limiting factors and optimize the system design (AGRAWAL et al, 2022).…”

This technical article focuses on determining the maximum power transfer capacity of spur gears mounted on shafts with spline bushes using an interference fit. Spur gears play a crucial role in power transmission systems, and the use of spline bushes with an interference fit provides enhanced stability, load distribution, and safety. The gear is mounted on the spline bush, which, in turn, is mounted on the shaft using interference fit. This arrangement ensures that in case of torque overload, the interference fit allows the spline bush to slip preventing mechanical structural failure of the transmission elements. Understanding the maximum power capacity of these gear systems is essential for ensuring reliable and efficient operation. The article provides an overview of spur gears, spline bushes, and the benefits of an interference fit. It explores the factors influencing power transmission and presents analytical methods for calculating critical parameters. A case study calculation is included to demonstrate the application of the discussed methods. Design considerations and optimization techniques for enhancing power capacity are also discussed. By determining the maximum power transfer capacity, engineers can make informed design decisions, optimize gear systems, and ensure both reliable power transmission and safety.

“…Straight gears, or cylindrical gears, are the most common type of gear because of the simplicity of design and manufacture, and because they are cost-effective and require less maintenance [2,[6][7][8]. They are usually used to transfer power to parallel shafts [9][10][11]. Many analyses are presently being conducted to determine when damage or defects occur due to gear bending.…”

“…Many analyses are presently being conducted to determine when damage or defects occur due to gear bending. From these, it can be concluded that bending failures usually occur when the yield strength of the material is exceeded [3,6,9,12]. With the increase in interest, as well as the frequency of use of gears, designing a gearbox for the required conditions has become a demanding task [13][14].…”

The paper presents an analysis of selected design solutions for spur gears with reduced weight, in which the results obtained are compared to a solid gear without modifications. The reduction of the weight of the gears is of particular importance, among others in the automotive and aviation industries, where it reduces energy consumption, and thus CO 2 emissions. It is also important to remember to maintain the required strength parameters when reducing the mass of the gear. This article focuses on the analysis of deformation and stress due to a given load on the considered weight-reduced gears. The values of the obtained static analysis results of the reduced-weight gears were also compared to the base gear.
