    The structural characteristics and installation of the serpentine spring coupling

    Release Date: 2020-11-01 Publisher: Ever-Power Machinery

     Serpentine spring couplingIt is a metallic coupling with a structure that relies on the serpentine spring to axially embed the two halves of the coupling by more than 36%. The serpentine spring with trapezoidal section is made of high spring steel, which has undergone strict heat treatment and is processed. It has a good The mechanical properties of the coupling, so that the service life of the coupling is much longer than that of the non-metal elastic element coupling.The spring of the trapezoid cross-section and the trapezoidal tooth groove are particularly convenient and tight, so that the assembly, disassembly and maintenance are easier than general couplings.The coupling is allowed to have a large installation deviation. Because the spring 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.

    Installation and use of serpentine spring coupling:
    1. Align the installation and control the reasonable deviation. Although the serpentine spring coupling allows a large installation deviation, it should also be within the specified value during installation.
    2. Align the gap and angular deviation between the two halves of the coupling. Measure the gap between the two coupling halves every 90° during installation, and the difference between the large value and the small value does not exceed 0.38mm.
    3. Correct the radial deviation.Place a ruler on the two-part coupling, and measure it every 90°. Use a ruler to check that the radial deviation does not exceed 0.38mm.
    4. It is better to choose a suitable grease that has an oil injection point temperature of ≥150℃, which can resist centrifugal force, has separation stability, no impurities, and does not corrode carbon steel and rubber.
    5. Filling a sufficient amount of grease with sufficient lubricating grease is important for the work of the coupling, and it is recommended to check it once a year.Use a dry grease gun to inject grease until there is excess grease overflow in the hole.
