Bevel gear is an important transmission component, which is used to achieve the transmission between 90 degrees of cross shafts. Unlike straight cylindrical gears, bevel gears can achieve a higher transmission ratio and lower noise. With the development of science and technology, bevel gear processing technology is continuously optimized, so that its transmission performance can be improved.

There are many kinds of bevel gear processing methods, mainly divided into mechanical processing and forging processing two categories. Machining includes milling, planing, slotting, rolling and other methods for bevel gears of different types and materials. The advantage of machining is that it can obtain high precision and surface quality, the disadvantage is that the processing efficiency is low, the cost is high, and it is only suitable for small or medium batch products. Forging process is to mass produce high-precision bevel gear products through a series of process control such as heat treatment, forging and finishing of the billet. The advantage of forging processing is that it can greatly improve production efficiency and reduce costs, but the disadvantage is that it can not adapt to all shapes and sizes of bevel gears, and it also needs to carry out subsequent finishing and heat treatment and other processes after forging.

With the development of numerical control technology and CAM software, bevel gear machining is developing in the direction of precision and intelligence. Complex shapes and high precision bevel gears can be realized by using five-axis CNC machine tools. By using CAM software to compile NC program, machining efficiency and accuracy can be improved, while human error and waste can be reduced.

In summary, bevel gear processing technology continues to innovate, from traditional machining to advanced automatic forging production, and combined with numerical control technology and CAM software to improve precision and intelligence. Improved production efficiency and product accuracy. This accelerates the wide application of bevel gears and makes them play a greater role in the field of mechanical transmission. It is believed that with the progress of science and technology, the processing and manufacturing of bevel gears will reach a higher level and better meet the transmission needs of industrial products.
