Gear research, production and production at home and abroad have been put into production for many years, and fruitful results have been achieved. With the rapid development of various industries, the demand for spiral bevel gear is increasing day by day. However, at present, most of the production of spiral bevel gear at home and abroad still adopts traditional processing methods, and various deficiencies are becoming more and more obvious. The precision forging of spiral bevel gear can achieve one-time forming to obtain a complete tooth shape, and the tooth surface of spiral bevel gear can be directly put into production without or only a small amount of precision machining. Its characteristics are as follows:
1.The structure and performance of spiral bevel gear have been improved
The spiral bevel gear blank is forged at high temperature. In the plastic forming process, the blank is pressed in three directions, the metal streamline of the blank is distributed uniformly and continuously along the spiral tooth shape, the grain and internal structure are refined, the micro defects are reduced, the strength and impact strength of the spiral bevel gear can be increased by more than 20%, and the service life can be prolonged by one time.
2.Reduce energy consumption, reduce costs and enhance market competitiveness
The traditional spiral bevel gear processing adopts cutting processing, which is labor-consuming, time-consuming and waste of materials. However, the spiral bevel gear after precision forging can be directly used without or only a little processing, which saves a lot of metal materials and machining costs, and can significantly improve the production efficiency and economic benefits of manufacturers, so as to enhance the market competitiveness. According to the calculation, the material utilization rate can be increased by about 40% and the production efficiency can be doubled, The production cost can be reduced by more than 30%.
Precision forging of spiral bevel gear is a new material-saving and efficient spiral bevel gear processing technology, which plays an important role in improving the technical level of China’s spiral bevel gear manufacturing industry, and is of positive significance to the improvement of the quality of China’s equipment manufacturing industry and the development of national economy.
