4. The main technical results of our company on the processing technology of bevel gears

1) Owns six practical new patents on the processing technology of bevel gears
2) Large processing range: Max diameter 8000mm with unlimited modules

3) Accuracy can up to DIN5 level
4)  "R" shape technology on dedendum to disperse the processing stress,save cost,enlarge contact area to

increase torque transmission etc.
5)  Carbide stick knife processing instead of traditional knife disc processing in order to increase the processing efficiency and precision level.
6)  By adding an indexing head on our 5-axis machining centers,we are able to achieve the processing of integral type large bevel gear shafts.
7) Sprial bevel gear format: Gleason or Klingelnberg

8) Our company's project of "arc bevel gears and gear shaft for 3000-kw above vertical mill reducer has earned it the Chongqing "Key New Product" Certificate of honor and got the support by the National

Science and Technology Innovation Fund
9) Our Company's double twist transmission high accuracy spiral bevel gears have been successfully applied to the ship lift of the Three Gorges Dam water control project to have replaced the imported products.
