JS type serpentine spring coupling
JS type serpentine spring coupling is suitable for coaxial transmission shaft system, and has the ability to compensate the angular, radial and axial offset between the two shafts.
Working temperature is -30-150℃.
Structural features of JS serpentine spring coupling:
1. Good vibration damping and long service life.
2. It can withstand a wide range of load cut-off and start-up.
3. Transmission and operation.
JS type serpentine spring coupling is a structured metal elastic 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 performance of the reed, the resonance phenomenon between the prime mover and the working machine is largely avoided. , The service life is much longer than that of 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 large load changes. The short-term overload capacity is 2 to 3 times the rated torque, the transmission efficiency is 99.5%, and the operation; and the serpentine spring coupling has a simple structure, easy assembly and disassembly, and allows large installation deviations. It is suitable for impact crushing Coal machine, serpentine spring coupling rock crusher, crank reciprocating motion, mining, heavy machinery, reducer, etc.
