Hypoid gears are widely used in automobile, aircraft, ship, machinery, high-precision processing equipment and other fields. Its transmission has the characteristics of high efficiency and stability, and can withstand large loads. The demand is quite large. At present, China’s hypoid gear manufacturers are relatively backward in technology. They mainly rely on the purchase of complete sets of foreign numerical control machine tools or imitation machine tools to produce hypoid gears, which can only play a production role. The adjustment and processing are relatively slow and cannot adapt to the rapid changes in the market. In particular, the production of high-precision hypoid gears still fails to meet the requirements, the core technology is still not fully mastered, and the innovation ability is relatively low. Moreover, China’s automobile industry has ushered in the peak of vigorous development, with large demand and good market prospects. It is urgent to improve the quality and performance of products, develop national independent brands, adhere to the road of independent innovation, and narrow the gap with developed industrial countries as soon as possible.
With the development of modern industry, the performance requirements of hypoid gear transmission are getting higher and higher. The traditional design and calculation methods can not meet the requirements, and there are many design defects, which can not meet the requirements of all walks of life. The design still needs to be improved and perfected. In terms of high-precision hypoid gear transmission, the design principle can no longer meet the hypothetical conditions, and the machining calculation principle is no longer applicable. The original calculation method will produce large errors, and the calculation method needs to be improved. In processing and manufacturing, the application of advanced technologies such as numerical control technology and computer-aided analysis plays an increasingly important role in guiding production.
Therefore, the simulation of hypoid gears and the research of finite element method are of great significance for improving the manufacturing and processing accuracy of hypoid gears, for improving the service life of hypoid gears, for developing high-precision instruments, for the long-term development of China’s automobile industry, for making great progress, and even for becoming an advanced manufacturing country in the world.
