“…The displacement in the gear, on the other hand, is closely related to the design variables (R-sq over 99%) and the volume reduction (R-sq above 90%). If compared with another study by [23] for traditional gear reduction methods such as holes or ribbed; then analysing the similarity with Fig. 13 and Fig.…”

“…This adjustment is more scientific with the regression equation being derived from the FCCCD method, which is controllable, and completely independent of experience. According to the results of [23], it can be seen that the traditional method has about 24% larger displacement than the solid gear, but the material reduction is only about 15%. While (Table 12 No.…”

Nowadays, plastic gears are more commonly used. The Triply Periodic Minimal Surfaces (TPMS) structure can perfect the design to reduce weight but still achieve the desired workability criteria. It can also be adjusted more easily and scientifically than the empirical structure optimization based on experience. Currently, the fabrication of gears with complex internal structures such as TPMS is possible thanks to 3D printing technology. This study investigates the mechanical properties of a TPMS structure when applied to Polyetheretherketone (PEEK) plastic gears. The research content includes displacement, deformation, and Von-mises stress to evaluate the stiffness and strength of gears. The structure used to optimize the gear mass is the Gyroid structure, developed in the cylindrical cell map and studied in the paper. The goal of the research is to apply the Gyroid structure to optimize mass while still ensuring gear performance. This study not only offers new insight into the importance of the control variables for TPMS structures but also provides a mass lean process for gear designers. It uses experimental design methods to choose a suitable topology structure, and the final research result is a regression equation, which clearly shows the close relationship between the volume reduction and displacement with the specified control variables of the unit cell. From there, it is possible to determine the proper amount of material reduction while ensuring the working ability of the gear transmission.

“…The spherical pitch curve is not a circle. In addition to its symmetry, any two teeth have different tooth profile curves, and the left and right tooth profile curves of a tooth are also different [8][9][10][11][12][13], which causes large vibration and impact in the transmission process of non-bevel gears.…”

There are problems with vibration and impact in the meshing transmission process of non-bevel gear. Therefore, a simulation control method of non-bevel gear transmission based on ADAMS and MATLAB is proposed. First of all, the design modeling of non-bevel gear is briefly described, and the influence of order and eccentricity on its transmission ratio is analyzed; Then, the established non-bevel gear model is imported into ADAMS, and the constraint, motion pair, driving force, input and output variables are set. The data transfer relationship is established by using the ADAMS/Control module and MATLAB/Simulink interface, and the non-bevel gear mechanical system module is generated in MATLAB/Simulink; Finally, its joint simulation control system is built in the MATLAB/Simulink module, and its control simulation analysis is carried out. The research results show that by comparing and analyzing the simulation results of only constant value input and adding the PI control module, the amplitude, and frequency of the angular velocity and angular acceleration curves of the driven wheel are significantly reduced, that is, the vibration and impact in the non-bevel gear transmission are reduced, which verifies the correctness and feasibility of the control strategy, It provides a new method for the control design and development of the vibration reduction performance of non-bevel gear transmission; The result is beneficial to the application and popularization of non-bevel gears.
