Features of serpentine spring coupling

Features of serpentine spring coupling:
1. Good vibration damping and long service life.The coupling is axially embedded in the two halves by a serpentine spring leaf for more than 36%.The serpentine spring leaf with trapezoidal section is made of high-quality spring steel, subjected to strict heat treatment and special processing. It has good mechanical properties, so that the service life of the coupling is much longer than that of the non-metal elastic element coupling (such as elastic Set of pin, nylon rod pin coupling) greatly increased.
2. High transmission efficiency and reliable operation.The transmission efficiency of the coupling is determined to reach 99.47%, and its short-term overload capacity is twice the rated torque, and the operation is reliable.
3. Large range of bearing variable load, starting *.The tooth surfaces of the two half couplings in contact with the reeds are arc-shaped. When the transmission torque increases, the springs will deform along the curved surfaces of the teeth, so that the force points of the two half couplings on the reeds are close.The contact point between the reed and the tooth surface, that is, the change of torque, changes with the size of the transmitted torque, and its transmission characteristics are variable stiffness.Therefore, it has a greater load variation than general elastic couplings.The cushioning effect produced by the transmission force when the reed deforms along the tooth arc, especially when the machine is started or strong impact load, to a certain extent, has the security of protecting the supporting parts.
4. Low noise and good lubrication.The aluminum alloy shell protects the spring from being thrown out during operation, and the shell is filled with butter, which not only makes the lubrication good, but also makes the noise when the reeds engage is absorbed by the butter damping and eliminated.
5. Simple structure, convenient assembly and disassembly.The whole machine has few parts, small size and light weight. The spring leaf designed as a trapezoidal cross-section and the trapezoidal tooth groove are particularly convenient and close, so that the assembly, disassembly, and maintenance are simpler than ordinary couplings.
6. Large installation deviation is allowed.Because the spring leaf and the tooth arc surface are in point contact, the coupling can obtain greater flexibility.It can be installed to work normally under conditions of radial, angular and axial deviations at the same time.
