A machining method of Cycloid Bevel Gear and hypoid gear pair based on gear wheel plastic forming is explored, which greatly improves the manufacturing efficiency of Cycloid Bevel Gear and hypoid gear pair. This method belongs to a semi generative processing method, in which the gear pinion is processed by the non generative cutting method and the gear is milled continuously, and the gear wheel is processed by the precision forging method.
(1) The principle of the new semi generative machining method is discussed, and the meshing characteristics of the tooth surface are studied. The calculation method of the gear cutting adjustment of the gear pinion and the mathematical model of the gear tooth surface, as well as the three-dimensional digital model of the gear pinion and the gear wheel are established;
(2) According to the tooth contact analysis, the law of gear tooth surface modification is studied;
(3) Taking cycloid hypoid gear pair as an example, the feasibility of the new method is verified by tooth contact analysis and visual analysis;
(4) The experiment and analysis of Cycloid Bevel Gear and hypoid gear pair are completed by printing technology. The experimental results show that the tooth profile obtained by the new semi generative machining method meets the design requirements;
(5) According to the gear tooth shape, the mold cavity model of the gear wheel is established, and based on the simulation research of the general NC machining of the digital tooth surface, the general machining simulation of the gear wheel cavity is completed, which provides a technical basis for the machining of the gear wheel mold.
The research on semi generative machining method of Cycloid Bevel Gear and hypoid gear based on plastic forming of large gear provides a theoretical basis for high-efficiency manufacturing of Cycloid Bevel Gear and hypoid gear pair.
