JS type serpentine spring coupling

The tooth type of JS serpentine spring coupling is curvilinear: when the load is small, the straight part of the serpentine spring is basically parallel to the axis to be connected; when the load increases, the deformation of the serpentine spring increases, and the contact arc with the tooth The surface also increases, and the distance between the contact point with the tooth becomes shorter and shorter, and the stiffness increases. The relative rotation angle of the two halves of the coupling has a non-linear relationship with the transmitted torque, which is a variable-rigidity serpentine spring coupling. Device.The linear tooth profile is easy to process and low in cost, but it is only suitable for working conditions with small changes in the transmission torque.Curved tooth couplings are suitable for large torque changes and positive and negative working conditions, and have a good cushioning effect, but the curved tooth shape has poor manufacturability and high manufacturing costs.

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 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 large installation deviations are allowed.
