The serpentine spring coupling is a kind of metal elastic coupling with advanced structure. It transfers torque by the serpentine spring sheet. The serpentine spring coupling is the most advanced shaft coupling transmission component in the international machinery industry today. There are nine types of serpentine spring couplings that are very common for shaft coupling and transmission components. They are the JS shell radial mounting type (basic type) serpentine spring coupling,
JSB housing axial installation type serpentine spring coupling, JSS double flange connection type serpentine spring coupling, JSD single flange connection type serpentine spring coupling, SJS connection intermediate shaft type serpentine spring coupling , JSG high-speed serpentine spring coupling, JSZ serpentine spring coupling with brake wheel, JSP serpentine spring coupling with brake disc, JSA safety serpentine spring coupling, etc.
The main structure of the serpentine spring coupling is composed of two half couplings, two half outer covers, two sealing rings and a serpentine spring sheet.It transfers torque by embedding the serpentine spring into the tooth slots of the two coupling halves, and the coupling uses serpentine spring sheets to be embedded in the tooth slots of the two coupling halves to realize the link between the driving shaft and the driven shaft.During operation, the driven end is driven by the axial force of the active end tooth facing the snake spring to transmit torque, which largely avoids the occurrence of resonance phenomenon and the elastic variable generated by the reed when transmitting torque , So that the mechanical system can obtain a better damping effect, with an average damping rate of more than 36%.
