    Structural features and installation techniques of plum-shaped elastic coupling

    Release Date: 2020-11-28 Publisher: Ever-Power Machinery

     Plum-shaped elastic couplingIt is mainly composed of two protruding teeth that are closely meshed and subjected to radial compression to transmit torque. When the two axes are relatively offset, the elastic element undergoes corresponding elastic deformation and plays a role of automatic compensation.Plum-shaped elastic couplings are mainly suitable for frequent starting, forward and reverse rotation, medium and high speed, medium torque and high demanding work occasions, such as: metallurgy, mining, petroleum, chemical industry, lifting, transportation, light industry, textile, water pump , Fan, etc.Working temperature -35%℃ ~+80℃, transfer nominal torque25~12500Nm, Allowable speed1500~15300r / min.

    Installation skills of plum-shaped elastic coupling:

    XNUMX. Before installation, first check whether the prime mover and the working machine are concentric, whether there are wrapping paper and scratches on the surfaces of the two shafts, whether there are debris in the inner holes of the two half couplings of the plum coupling, and whether the edges of the inner holes are If there are bruises, the shaft and half coupling should be cleaned up, and the bruises should be treated with a fine file. Then check whether the inner hole diameter and length of the two half couplings are consistent with the diameter and shaft elongation of the prime mover and working machine.In general selection, make the length of the prime mover and the working machine end half coupling less than its shaft elongation1030 mmAs well.

    XNUMX. The coupling uses engineering plastics as elastic components, cushioning, damping, and working temperature-35%Every time- + 80Degree; maintenance-free

    XNUMX. The elastic body is embedded in the convex claw block to avoid internal deformation caused by impact and external deformation caused by centrifugal force.The large concave surface of the protruding claw makes the surface pressure on the involute tooth very small. Even if the tooth is overloaded, the tooth will not wear and deform..

    Fourth, the nominal torque is an elastic body92shATime value, use98shAWhen the torque is increased by approximately one percent70.

    The plum-shaped elastic coupling has the following characteristics:

    XNUMX. Stable work, with good vibration damping, buffering and electrical insulation properties.

    XNUMX. Simple structure, small radial size, light weight, small moment of inertia, suitable for medium and high speed occasions.

    XNUMX. It has large axial, radial and angular compensation capabilities.

    XNUMX. Polyurethane elastic elements are resistant to oil, have large carrying capacity and long service life.

    XNUMX. The coupling does not need to be lubricated, the maintenance workload is small, and it can run continuously for a long time.
