There are 10mm-1600mm diameter, 1-36 modulus, and GB5-GB8 accuracy level of spiral bevel gears. According to the different design methods, processing methods, and processing equipment, spiral bevel gears can be divided into German Klingelnberg spiral bevel gears, American Gleason spiral bevel gears, and Swiss Oerlikon spiral bevel gears, which are usually called Klingelnberg spiral bevel gears, Gleason spiral bevel gears, and Oerlikon spiral bevel gears. There are some minor differences between these different types of spiral bevel gears, but there are many similarities in the main parameters. According to the application environment of spiral bevel gears, various parameters are also very different. According to the use environment, spiral bevel gears can be divided into centrifugal powder separator series spiral bevel gears, vertical coal mill spiral bevel gears, textile machinery series spiral bevel gears, reducer series spiral bevel gears, automobile variable speed transmission series spiral bevel gears, steel rolling machinery series spiral bevel gears, mining machinery series spiral spiral bevel gear, wheel loader series spiral bevel gear, lateral mixer series spiral bevel gear, DCY reducer spiral bevel gear, DBY reducer spiral bevel gear, universal milling head spiral bevel gear, wire drawing machine series spiral bevel gear, cement vertical mill spiral bevel gear, oil field drilling rig series spiral bevel gear, engineering machinery series spiral bevel gear, high frequency welded pipe spiral bevel gear, stainless steel welded pipe spiral bevel gear spiral bevel gears, pipe making machinery spiral bevel gears, cold bending machine spiral bevel gears, hardened spiral bevel gears and other series of spiral bevel gears.
