Serpentine spring coupling is a kind of advanced structure of the metal elastic variable stiffness coupling, it depends on the serpentine spring grid which is embedded in the two halves of the coupling slot to transfer torque.It is mainly composed of two steel hub, a high strength serpentine spring grid,two seals and a cover. The elastic deformation of serpentine spring in the hub groove can overcome deviation of centralization and axial movement of two connected shaft.Therefore, the coupling transmit torque by serpentine spring grid , can effectively absorb the impact load and overcome some of the deviations at the same time. The transmission characteristics and advantages of serpentine spring coupling are as follows: Good vibration-dampening performance and long service life
Trapezoidal section grid is made of high quality spring steel, it is heat-treated strictly and through special processing,it has good mechanical properties, so the service life of the coupling is much longer than nonmetallic couplings (such as elastic sleeve coupling, nylon pin coupling). A wide range of load,starting safely
The contact surface between two hubs and grid is curved shape, when the torque is increasing, the grid will be deformation with the curved tooth face, it make the force that two hubs load on grid is closed.The point of force between two hubs and grid is changed, namely the moment is changed, it is depend on the torque change, transmission characteristics of torque are varying stiffness. So it can bear larger load change than the common flexible coupling . High transmission efficiency, high reliable services
The transmission efficiency of the shaft device is determined by 99.47%, its short-time overload capacity is two times of the rated torque, the machine runs safely and reliably.
Low noise and good lubrication
Aluminum-alloy cover can avoid the grid be thrown out during the machine running,Grease filled into the cover to assure good lubrication,and absorbing noise. Simple structure, convenient assembly and disassemble
It is made of only a few parts, with small volume and light weight. It is more convenient of meshing of trapezoidal section grid and the trapezoidal grooves, so that makes it easier than common coupling on assembly,disassemble and maintenance. Large allowable deviation of installation
As the contact between grid and curved tooth is coincident automatically,it can work normally with radial,angular and axial assembly deviation.
