1. The coupling is axially embedded in the two halves with a serpentine spring leaf for more than 36%.The serpentine spring leaf of the 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 sleeve). Column pins, nylon rod pin couplings) have greatly increased.
2. Since 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.
3. The tooth surfaces of the two half couplings in contact with the reeds are curved. 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 magnitude of the transmitted torque. Its transmission characteristics are variable stiffness, so it has a greater load variation than ordinary elastic couplings. .The transmission force causes the buffering effect of the reed to follow the tooth arc, especially when the machine is started or strong impact load, to a certain extent, to protect the safety of the supporting parts.
4. 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 tight, so that the assembly, disassembly and maintenance are easier than ordinary couplings.
5. The aluminum alloy casing protects the spring from being thrown out during operation, and the casing 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.
6. The transmission efficiency of the coupling has been determined to reach 99.47%, and its short-term overload capacity is twice the rated torque, and the operation is safe and reliable.
