HangzhouSnake spring coupling

The serpentine spring coupling is a structured metal elastic coupling.It relies on serpentine springs to transmit torque.Its transmission characteristics and advantages are as follows:

1. The serpentine spring coupling has good vibration damping and long service life. The coupling is axially embedded in the two halves with serpentine spring blades for more than 36%.The serpentine spring leaf of the trapezoidal 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. With a large range of 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 arc of the teeth to make the two half-couplings The point of force acting on the reed is 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 cushioning 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. Transmission, operation, and the transmission efficiency of the coupling is determined to reach 99.47%, and its short-term overload capacity is twice the rated torque.

4. Low noise, lubricate the aluminum alloy casing to protect 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 of the reed meshing is absorbed by the butter damping.

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 section and the trapezoidal tooth groove are particularly convenient and close, so that assembly and disassembly and maintenance are easier than ordinary couplings. .

6. Larger 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.
