“…A face gear tooth is considered an undevelopable ruled surface according to the theory proposed by Litvin [1][2][3], which limits the development of new face gear generation methods. However, most manufacturing methods for face gears currently depend on this theory [4][5][6][7][8][9][10].…”

“…However, this method can only be used for soft or low-precision tooth surfaces. The tools used to generate face gears containing hard or high-precision tooth surfaces are worm cutters or grinders [10] and disk cutters or grinders [5][6][7][8][9], which both duplicate the involute of the pinion. Although the indexing motion of the worm cutters/grinders is continuous, the generated surfaces are in point contact, the tool needs transverse motion in the longitudinal direction to process the whole tooth surface, and the processing efficiency is not very high.…”

The conventional tooth surface of a face gear is difficult to manufacture, and the cutter is not uniform even though the parameters of its mating pinion slightly change. Based on the analysis of the features of the tooth surface, a new developable ruled surface approach is proposed that defines the tooth flank of the face gear, for which the most important feature is that it could be generated by a straight-edged cutter. This study presents mathematical models of the cutter and the new tooth surface and the corresponding deviation, correction and generation method for this surface, which are investigated through numerical examples. The manufacturing process is simulated by VERICUT software, and the results demonstrate that even when the principle deviation is added to the machined deviation, the absolute deviation is on the microscale. The meshing and contact simulation shows that the new surface could obtain good meshing performance when the number of face gear teeth is greater than three times the number of pinion teeth. This research provides a new method for manufacturing face gears.

“…Actually, the trajectory of the meshing points between face gear and cylindrical gear is not stable completely, which is affected by the factors such as overlap ratio, tooth meshing points, and so on. 26 Therefore, it is necessary to divide the area before and after the meshing to calculate the transmission efficiency accurately. As shown in Figure 10, the entire meshing line can be divided into four parts.…”

A planetary gear transmission system with multistage face gears combinations as core component can easily realize the variable speed in differential transmission ratios with structural advantages. In order to improve the transmission stability and loading capacity, it is necessary to set up a reasonable kinematic model for multistage face gears pair. This study focuses on the kinematic characteristics of multistage face gears structure with double crown surface by the methods of numerical calculation and experimental verification. The transmission error and efficiency solving models are established by numerical calculation method to analyze the influences of each factor in detail. Then the correctness of the above numerical models are verified with transmission error and efficiency experiment. In addition, the numerical results are compared with the experimental results to further indicate the important influences of the multistage face gears components on the transmission error and efficiency of whole transmission system. The results can provide references for the dynamic and experimental study of multistage face gears in some degree.

“…However, the honing speed between honing wheel and gear is too slow to meet the required honing speed of hardened surface gear honing. e abrasive grit falls off from the honing wheel leading to block because of the cutting force increasing caused by the slow honing speed [5,6]. e ultrasonic machining can improve honing speed, reduce cutting force, and avoid blocking to enhance the processing efficiency.…”

Applying the ultrasonic machining in gear honing can improve honing speed, reduce cutting force, and avoid blocking. There are two problems leading to the decrease of calculation accuracy in the traditional nonresonant theory of the ultrasonic gear honing. One is that one-dimensional longitudinal vibration theory and two-dimensional theory cannot reflect the vibration characteristics of ultrasonic horn and gear comprehensively. And, the other one is that the difference of the analysis dimension between the two theories leads to mismatch of the coupling condition dimension between ultrasonic horn and gear. A free vibration analysis through Chebyshev–Ritz method based on three-dimensional elasticity theory was presented to analyze the eigenfrequencies of the horn-gear system in ultrasonic gear honing. In the method, the model of the horn-gear system was divided into four parts: a solid circular plate, an annular plate, a solid cylinder, and a cone with hole. The eigenvalue equations were derived by using displacement coupling condition between each part under completely free boundary condition. It was found that the eigenfrequencies were highly convergent through convergence study. The hammering method for a modal experiment was used to test the horn-gear systems’ eigenfrequencies. And, the finite element method was also applied to solve the eigenfrequencies. Through a comparative analysis of the frequencies obtained by these three methods, it showed that the results achieved by the Chebyshev–Ritz method were close to those obtained from the experiment and finite element method. Thus, it was feasible to use the Chebyshev–Ritz method to solve the eigenfrequencies of the horn-gear system in ultrasonic gear honing.
