　　JSJ type coupling with intermediate shaft is a kind of structural metalFlexible coupling.It uses a serpentine spring leaf to be axially embedded in the tooth grooves of the two halves of the coupling to realize the connection between the prime mover and the working machine. Due to the special performance of the reed, the resonance between the prime mover and the working machine is largely avoided. Phenomenon, the service life is much longer than the non-metal elastic element coupling; the tooth surface contacted by the reed is arc-shaped, and the size of the contact surface changes with the size of the transmitted torque, so it can withstand greater load changes. The short-time load capacity is determined to be 2 to 3 times of the rated torque, the transmission efficiency is 99.5, and the operation is reliable; and the serpentine spring coupling has a simple structure, convenient assembly and disassembly, and allows large installation deviations. It is suitable for impact type Coal crusher, serpentine spring coupling rock crusher, reciprocating crank, mining, heavy machinery, reducer, etc.
