Processing principle of high precision spiral bevel gear
Theoretically speaking, the machining of high-precision spiral bevel gears is completely universal, so theoretically there is no need to calculate the direction and curvature of the vector, and its complexity is equivalent to the axis value. Therefore, simply comb three gears with the basic condition of the same height as the arc wheel, also known as the arc wheel. Viewed from the side, it is a flat gear. Its research and development principle is to polish the high teeth on the basis of the swing arc. In the process of processing, the factory usually cuts a small amount of "contact area" of the gear in the production mode according to the plane of the gear as a starting point, and combines the cutting machine with the shaft to realize the processing of the shrinking gear.
The processing principle of high-precision spiral bevel gear: the simulation wheel is the processing gear, and the unified chuck is the imitation gear tooth. When the simulated wheel is combined with the breaking element, the cutter head cuts off the gear teeth. How to deal with large and small wheels, calculating the correct value is the main problem that needs to be solved. Many experts and scholars at home and abroad have done a lot of research and published a lot of papers and professional work, especially for arc bevel gears and reduced-tooth hypoid gears. Since the large and small wheels are processed into flat-top production wheels, their orientation and curvature need to be calculated, and the contact analysis is very complicated, and it is difficult to obtain ideal results in reality. With the popularity of controllable gear machine tools and grinding technology, the processing methods of gear systems in my country have developed rapidly. They both use high teeth, like cycloids, with simple calculations and better contact area than constriction. The results show that the use of circular arc contour teeth is an ideal choice in the processing of small batch products, especially in the processing of high-precision spiral bevel gears.
As a key transmission component in the automotive, petroleum, energy and aerospace industries, its theory, design, processing technology and innovation capabilities are important symbols of the development level of the country's manufacturing industry. At present, the spiral bevel gear industry has begun to combine high-precision spiral bevel gear technology with computer technology and intelligent manufacturing technology. New and more mature theoretical designs, processing heat treatment technologies and new materials are constantly emerging, and the quality of spiral bevel gears is constantly improving. my country's research on spiral bevel gears is relatively late, so it is more necessary to improve domestic spiral bevel gear technology through continuous innovation to meet future challenges.
