Spiral bevel gearDevelopment trend

Currently,Spiral bevel gearIt has been widely used in industries such as automobiles, and the technology is relatively mature.However, with the integration of computer technology and intelligent manufacturing and spiral bevel gear technology, there is still a lot of room for development in the design, processing, and testing of spiral bevel gears.The main development directions are as follows:

(1) In terms of design theory research, high-order motion error curve design, reconstruction of true numerical tooth surface based on discrete data points, and optimization of tooth surface structure using tooth surface loading contact analysis (LTCA) [36-38], etc. More and more applications are used in the design of spiral bevel gears to obtain gears with smaller tooth surface errors and higher transmission stability. At the same time, if the theoretical tooth surface gears processed by the machine tool set parameters are processed in the design stage Carry out dynamic analysis, use tooth surface modification technology to obtain cutting parameters for actual processing, and will also appear more in the design to reduce the number of trial cuts;

(2) In terms of manufacturing, with the emergence of CNC Free-Form machine tools and the popularization of CNC machining methods, more free space has been provided for the design and manufacture of tooth surfaces. Tooth surface error compensation provides the possibility [39].The maturity and popularization of CNC machine tools and the emergence and improvement of network-based CAX integrated manufacturing technology and its software platform [40, 41] will also encourage manufacturers to form their own closed-loop manufacturing systems;


(3) In terms of spiral bevel gears themselves, extreme size spiral bevel gears, high-speed spiral bevel gears and low vibration and noise spiral bevel gears will become the key development directions;

(4) In terms of heat treatment, explore clean heat treatment technology and tooth surface hardening technology of extreme size spiral bevel gears, induction hardening technology along the tooth profile of large modulus spiral bevel gears, traditional heat treatment, computer and intelligent manufacturing technology, etc. The key development direction of spiral bevel gears in the future.

6. Conclusion

Spiral bevel gear is a key transmission component in the automobile, petroleum, energy and aerospace industries. Its theory, design, processing technology and innovation capabilities are an important symbol of the highest level of manufacturing development.At present, the spiral bevel gear industry has begun to integrate spiral bevel gear technology with computer technology and intelligent manufacturing technology. New and more mature theoretical design, machining and heat treatment technology, as well as the continuous emergence of new materials, spiral bevel gears The quality of products has also been continuously improved.
