What are the advantages and disadvantages of profile teeth and tapered teeth?

Generally speaking, profile teeth refer to extended epicycloidal bevel gears, which are made in Alcorn and Krimberg. Bevel gear refers to spiral bevel gear, made by Gleason. Cycloid system and Gleason system are two main bevel gear tooth systems in the world at present. Just like the two schools, each has its own advantages. It's hard to say which performance is better or worse. As long as the machined gear has high precision, good quality and good performance. Some people in China have done experiments and come to the conclusion that Gleason system is better in strength, noise and stability, but the difference is not very big. Generally speaking, contour teeth need two machine tools and bevel teeth need five machine tools, aiming at mass production. In single-piece machining, the continuous indexing cutting efficiency of contour teeth will be higher, the whole process will be processed and the working procedures will be concentrated. Due to one-time clamping, both sides of the tooth slot are roughly and precisely cut out, and the adjustment of contact area is not easy to master. The bevel gear is machined by single-tool method in fine cutting of small wheel, and the convex or concave contact area can be adjusted independently. In application, Olcon and other high teeth are generally used in automobile industry, mainly in European automobile enterprises. In Japan, the United States, China, Russian and other countries, Gleason system is dominant. But at present, both Alcorn C series machine tools and Gleason Phoenix II machine tools can process two kinds of toothed gears. The future development will tend to assimilation. For China. Due to historical reasons, Gleason system was first used in China.
