The coupling with curved teeth is a coupling that realizes the connection of two half couplings by the meshing of internal and external teeth. Because the applied torque is always transmitted through the teeth. This not only reduces the load on a single tooth, but also ensures a very smooth rotating motion.

The coupling has the advantages of simple structure, high reliability and long life. Suitable for high speed, high power, high temperature and corrosion of the harsh environment; With large axial and Angle compensation ability, good anti-dislocation performance, with vibration absorption and vibration isolation function; No noise, zero clearance, constant speed, no lubrication, small radial size, large bearing capacity, often used for shafting drive at low speed and heavy load conditions, high precision dynamic balance gear coupling the device can be used for high-speed movement.
