Research on key technologies about design of mine-used crown gear coupling

The crown gear coupling is widely applied in mining and metallurgy field due to its small size, large transmit torque and high reliability etc. At present, there was no uniform criterion about design of the crown gear coupling, and less researches on its working characteristic, motion laws and meshing characteristic of tooth surface. The paper mainly analyzed and discussed the design methods, key design points of the crown gear coupling and the key technologies to increase the reliability of the crown gear coupling, which offered theoretical support for improving its design level and product quality.
