JSJ type to intermediate shaft coupling

The main structure of JSJ type intermediate shaft coupling is composed of two half couplings, two half outer covers, two sealing rings and serpentine springs.It transfers torque by inserting the snake spring into the tooth slots of the two halves of the coupling.Serpentine spring couplingThe serpentine spring sheet is embedded in the tooth grooves of the two half couplings 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, 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%.

JSJ type coupling with intermediate shaft is a structured metal elastic coupling.It uses a serpentine spring leaf to be axially embedded in the tooth groove 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 large load changes. Its short-term overload capacity is 2 to 3 times the rated torque, high transmission efficiency, reliable operation; and the serpentine spring coupling has a simple structure, convenient assembly and disassembly, and allows large installation deviations, and is suitable for impact crushing Coal mining machine, serpentine spring coupling rock crusher, crank reciprocating motion, mining, heavy machinery, reducer, etc.The serpentine spring coupling is a shaft connection transmission part in the mechanical field today, and it is also a very general shaft connection transmission part. It is widely used in shaft transmission of various machinery and equipment, usually with a motor connected to a shaft, a motor and a speed reducer. It can be applied where the box is weak or where the shaft is connected to the shaft.
