JSB snake spring couplings Characteristics

The JSB serpentine spring coupling used by machinery manufacturers in various regions is actually the associated serpentine spring piece axially embedded in the two halves of more than 36%. The snake-like spring of trapezoidal section is made of spring steel, which has been subjected to strict heat treatment and processed. It has good mechanical properties, so that the service life of the coupling is much longer than that of the non-metallic elastic element coupling (such as elastic sleeve pin, nylon rod pin coupling).

The tooth surface of the two half couplings of the JSB snake-like spring coupling contacting the reed is curved. When the transmission torque increases, the spring will deform along the tooth arc surface, so that the force point of the two half couplings acting on the reed is close. The change of the contact point between the reed and the tooth surface, that is, the torque, changes with the size of the transmitted torque, and its transmission characteristics are variable stiffness. Therefore, it can withstand greater load variation than the general elastic coupling. The cushioning effect generated by the deformation of the reed along the tooth arc caused by the power transmission, especially when the machine is started or under impact load, is important to protect the supporting parts to a certain extent.

JSB serpentine spring coupling of the whole transmission parts are less, and the volume is small, the weight is light, so it is designed into the trapezoidal section of the spring and trapezoidal groove of the fit is particularly convenient, close, so that the assembly and disassembly, maintenance than the general coupling is simple. JSB serpentine spring coupling because the spring plate and tooth arc surface is point contact, so the coupling can obtain greater flexibility. It can be installed in the case of radial, angular and axial deviations.
