Abstract
Spiral bevel gear axis intersection is the realization of the basis of motion transmission components, transmission due to its coincidence with a degree, the carrying capacity of the high transmission efficiency, smooth drive, noise, etc. have been widely used in automobiles, aircraft, machine tools and various mechanical products. Principle because of its complexity, resulting in adjustment of machine tool structure and processing of metal-cutting machine tools in all the most complex and long process. Thus, high-speed, high-precision. Bevel gears as a result of technical difficulty, only the United States the world's Gleason (Gleason), Switzerland Oerlikon (Orion, Culture and Sport) and Germany Klingelnberg three companies have the technology in this area, they respectively represent the three bevel gear types of system, and all into a system, and do not open. CNC technology has greatly simplified the machine body, and now these countries have already developed CNC machining of spiral bevel gear machine tools, the introduction of its refreshing. China's processing of spiral bevel gear research is still concentrated in "Gleason" machine area.Spiral bevel gear is a gear ratio according to the stability of a smooth, low noise drive transmission parts, in different places have different names, also known as arc tooth bevel gear, spiral bevel gears, spiral bevel gear umbrella, arc bevel gear , such as spiral bevel gear. convey the same torque required to drive the drive pieces of the provincial deputy space than belt , chain drive space for the required small size; spiral bevel gear transmission ratio of permanent stability, the stability of the transmission ratio is the transmission of various machinery and equipment in the transmission performance of the basic requirements; spiral bevel gear is reliable, long life.
