Spiral bevel gear is a kind of transmission part that can drive stably and low noise according to stable transmission ratio. It is also known as spiral bevel gear, spiral bevel gear, spiral bevel gear and so on. Spiral bevel gear has the characteristics of high transmission efficiency, stable transmission ratio, large arc overlap coefficient and high bearing capacity. It is widely used in automobile, aerospace, engineering machinery and other industries.
The theory of spiral bevel gear was first put forward by wildhaber of Gleason company in the United States. Later, Klingeinberg company in Germany and Oerlikon company in Switzerland also mastered the technology of producing spiral bevel gear. Gleason company adopts circular arc gear system, and Klingeinberg company of Germany and Oerlikon company of Switzerland adopt extended epicycloid gear system.
Most of China adopts spiral bevel gears and hypoid gears made by Gleason teeth in the United States. The difference between them is that there is no offset between the spiral bevel gear pinion shaft and the large axle, while the hypoid gear pinion shaft and the large axle are offset by a certain distance, which can make the transmission more stable and reduce the noise, Suitable for high-speed sports. In recent years, with the rapid development of automobile, engineering machinery and other industries, the demand for the variety and quantity of spiral bevel gear products is increasing. As the core part of the mechanical equipment industry, the manufacturing level of spiral bevel gear represents the development level of a country’s mechanical equipment industry to a certain extent.
