The main structure of the serpentine spring coupling is composed of two half couplings, two half shells, two sealing rings and a serpentine spring,as its spring shpe looks like a snake,so in China we usually call it snake spring coupling .
It relies on the spring embedded in the tooth groove of the two coupling halves to transmit torque. During operation, the axial force of main shaft to driving the other side shaft to transmit torque, so the resonance phenomenon is largely avoided. The elastic variable generated by the spring when transmitting torque,Which makes the machine obtain better vibration reduction effect, and its average vibration reduction rate is more than 36%.
Let see the drawing of this spring disc coupling
Bellow is the parameters of this spring motor coupling
