“…This method improves the fluidity of the metal, and improves the forging defects of the tooth tip of the spiral bevel gear, such as unfilled filling, cracks and the like [7]. Gao Zhenshan et al proposed an advanced hot forging method for spiral bevel gears which was helpful to improve the defects of insufficient filling of the gear tooth top, large forming load and low service life of die in traditional forging method [8]. Knust J. et al analyzed the impact of the hot-forging preform shape on forging quality, proposed an optimization design method for preform shape and conducted experimental verification [9].…”

The warm-forging technology of the spiral bevel gear (873 K–1073 K) was studied. Based on the rigid–plastic finite element method, a numerical simulation was carried out by using DEFORM V11.0 software to explore the influence of different process parameters on gear-forming quality and forming force in the process of warm forging. Taking into account the complexity of the geometry of spiral bevel gears and the diversity of the influence factors in the forging process, as determined through nine groups of numerical simulation experiments, this paper systematically analyzed the influence law of different forging speeds, die preheating temperatures, friction factors and workpiece heating temperatures on the effective stress and strain of spiral bevel gears. The best combination of process parameters with minimum forging force was obtained via the orthogonal experiment, which provides a theoretical basis for the optimization design of the precision forging process of spiral bevel gears and also provides a new idea for studying the precision-forging–forming process of other complex parts.

“…The usual processing method is cutting [11]. However, cutting large gears requires special machine tools and cutters, which results in high costs, numerous waste [12], and having low fault tolerance. Emelyanov et al [13] studied on the influence of changes in tool axis angle when large-module gears were machining.…”

Aiming at the problems of large amount of material cutting waste or large forming load when large gear profile forming adopts overall cutting or precision forging process, this paper proposed a three-roller bending process(TRBP) for large gear teeth profile, and analyzed the deformation mechanism of the rack bending, meanwhile the gear chain for roll forming was designed. Finite element analysis(FEA) was carried out to numerically simulate the load effects of both precision forging process and the TRBP for the large gear teeth profile in 17CrNiMo6. The effects of deformation force and strain of TRBP for large gear teeth profile were analyzed. The results showed that as the deformation temperature and speed increase, the deformation force and strain required by the gear profile gradually changes. And the reasonable parameter of TRBP is around 750 • C of deformation temperature and 0.5mm • s −1 of speed. Compared with the precision forging process under same boundary conditions, the deformation force of the gear profile TRBP has decreased by about 99% which could significantly reduce the tonnage requirement of deforming equipment.

“…The expressions establishments of tooth surfaces, cutting adjustments and detection as well as correction of tooth surface errors are more difficult, which decides the specificity of their machining modes [1]. The traditional machining method of spiral bevel gears is face-milling or face-hobbing, which must rely on a special machine tool [2].…”

The machining methodologies of spiral bevel gears based on universal computer numerical control (CNC) machine tools open up a new way for the flexible and diversified machining of spiral bevel gears. In order to improve the information interrelatedness and traceability in isolated machining mode of spiral bevel gears based on universal CNC machine tools, a novel integrated design and machining mode of spiral bevel gears based on universal CNC machine tools is proposed in this paper, and the spiral bevel gears integrated design and machining scheme is established. On this basis, a communication control framework for spiral bevel gear integrated design and machining is set up, and an information integration management system for spiral bevel gears is developed, which achieve the information communication and integration management of the whole spiral bevel gear integrated design and machining process. Finally, the feasibility and practicability of the integrated design and machining mode and the information integration management system are verified by the integrated design and machining example of one kind of spiral bevel gears. The proposed integrated design and machining mode accomplishes the isolated-to-integrated transformation of spiral bevel gear machining mode based on universal CNC machine tools and meets the modern integrated design and machining demands for spiral bevel gears based on universal CNC machine tools.
