Shandong snake type spring coupling

The serpentine spring coupling is a structural metal, which transmits torque by a serpentine spring sheet, and is a very versatile shaft coupling transmission component.

Advantages of serpentine spring coupling:

1. Good vibration damping and long service life.

2. Large range of bearing variable load, starting.

3. Transmission and operation.

4. Low noise and good lubrication.

5. Simple structure and convenient assembly and disassembly.

6. The whole machine has few parts, small size and light weight.

7. Large installation deviation is allowed.

Characteristics of serpentine spring coupling:

1. The coupling is axially embedded in the two halves by a serpentine spring leaf for more than 36%.The serpentine spring leaf of the trapezoidal cross-section is made of spring steel, which has undergone strict heat treatment and 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 pin , Nylon rod pin coupling) greatly increased.

2. 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 tooth-curved surfaces, 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 larger load variation than general elastic couplings.The buffering effect produced by the transmission force when the reed deforms along the tooth arc, especially when the machine is started or under impact load, can protect the supporting parts to a certain extent.

3. The transmission efficiency of the coupling is determined to reach 99.47%, and its short-term overload capacity is twice the rated torque.

4. 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 reed engage is absorbed by the butter damping.

5. 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.

6. 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.
