“…A standard cutting tool was used on the bevel gear processing machine, and the face gear tooth surface was obtained and paired with the pinion by optimizing the radial feed path and meshing parameters. Peng et al [22] studied the principle of the straight profile milling cutter in the processing of face gears. By defining the geometric shape of the cutter, an abstract model of the face gear was established via this method and a method for calculating the cutter movement parameters by the predesigned contact path and transmission error was proposed.…”

This paper presents a method of calculating and correcting of grinding face gears on an internal gear grinding machine. The generating principle of face gears is studied, and the feasibility of grinding motion on an internal gear grinding machine is analyzed. Then, the motions that need to be followed for grinding are analyzed based on the internal gear machine tool structure. Four main error sources causing tooth surface deviation in the grinding movements are proposed. The mathematical modeling of the grinding of face gears containing proposed error sources on an internal gear grinding machine is accurately established. The influence of the error sources on the topological deviations of the tooth surface is explored. A sensitivity matrix is established for the influence of various error factors on the tooth surface deviations. The correction values of each error factor are obtained in the case of existing tooth surface deviations. A theoretical correction result with zero-free tooth surface deviation is obtained via a least-square calculation. Finally, a virtual machining experiment on an internal gear grinding machine is conducted, which proves the accuracy of the proposed method for characterizing grinding and realizing corrections.

This paper proposed a designing and modeling method of a modified parabolic face gear and analyzed its tooth contact characteristics. Firstly, according to differential geometry and meshing theory, a parabola curve is introduced into the rack profile. And derived the equations of the generating gear, diamond wheel, worm and modified face gear. Secondly, a method for modeling the tooth surface of the modified face gear is proposed. Then, the influence of the modified parameters on the face gear is studied. Furthermore, the contact equations of the modified face gear and the cylindrical gear were combined to obtain the contact trace. Meanwhile, a coordinate analysis system with installation errors is established to obtain the contact traces and transmission error curves. Finally, the influence of the installation errors on the transmission error of the modified face gear under different modified parameters is analyzed. The results show that the modified face gear is susceptible to installation errors in the tooth width and tooth thickness direction.

“…In theory, the plane of the cutter should be in point contact with the face gear tooth surface; however, in practice, the generated tooth surface is constrained in line contact with the plane, which results in a large or macroscopic deviation between the generated and theoretical surfaces. 19 Tang and Yang 20,21 proposed milling and planning methods for face gear generation using simple tools. Although the accuracy of the tooth surface was guaranteed, all of these methods are profiling approaches, and the surfaces of the work-piece and cutter are in point contact.…”

The conventional tooth surface of a face gear is difficult to manufacture, and the cutter for the face gear cutting is not uniform even though the parameters of the pinion mating with the face gear slightly change. Based on the analysis of the geometry features of the tooth surface, a new developable ruled surface is defined as the tooth flank of the face gear, for which the most important geometry feature is that the flank could be represented by a family of straight lines, hence it could be generated by a straight-edged cutter. The mathematical models of the new ruled tooth surface, the cutter and the generation method are presented, the deviation between the ruled surface and the conventional surface, the correction of the ruled surface to reduce the deviation 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 micro-scale. 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.
