Serpentine Springs
Coupling springs are also commonly known as serpentine springs according to their appearance, but are defined as coupling springs according to their function. The torque range of the coupling spring is between 45N·M~800000N·M, the relative radial displacement of the two half shafts is between 0.5mm~3mm, the axial displacement is between 4mm~20mm, and the angular displacement is 1°15””. Coupling springs are often supplied in groups, such as 1 piece = 1 group; 2 pieces = 1 group and 4 pieces = 1 group and so on.
In the mechanical transmission system, the coupling spring plays the role of buffering and transmitting torque. Due to the advantages of high transmission efficiency, safe starting, simple structure and convenient disassembly and assembly of the serpentine spring coupling after matching, the product is widely used in metallurgy. Mining, lifting machinery, oil exploration, shipbuilding, coal mining and other equipment.
Common series of coupling springs: JS series coupling springs, which are mainly suitable for JS series serpentine spring couplings (JB/T8869-2000).

The Practical Application Of Coupling Serpentine Spring
The figure on the left is a typical matching example of the coupling spring, which is suitable for the JS series serpentine spring coupling.
The serpentine spring coupling is a kind of metal elastic variable stiffness coupling with advanced structure. It mainly relies on the serpentine spring to be embedded in the tooth groove of the two half couplings to transmit the torque, which is mainly composed of the two half couplings. , Two outer covers, two dense rings and serpentine springs.
The serpentine spring coupling also has the characteristics of high transmission efficiency, safe starting, and convenient disassembly and assembly.
