Shanghai LM type basic plum blossom elastic coupling

LM type basic plum blossom-shaped elastic coupling 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 to automatically compensate effect.

LM type basic quincunxFlexible couplingIt is composed of two half-couplings with the same shape of the protruding claws and elastic elements. The plum-shaped elastic element is placed between the two half-coupling protruding claws to realize the coupling of the two halves of the coupling.When changing the elastic element, the two halves of the coupling need to move along the axial direction to achieve the purpose of changing the elastic element.The allowable relative displacement of the two connected shafts is not only related to the size, but also to the shape of the working part of the elastic element. For the quincunx-shaped elastic element in contact with the torch-shaped claw, the allowable radial displacement △y is 0.2mm , The angular displacement △a is 1.5°, for the quincunx-shaped elastic element in contact with the arc-shaped claw, the allowable radial displacement △y is 0.5~1.8mm, and the allowable axis l-direction displacement △x is 2~5mm , The allowable angular displacement △a is 0°~1.0°.When the work needs to improve the compensation performance, and the load capacity is allowed to be slightly reduced, it can also be made into a drum-shaped plum-shaped elastic element along the axial direction, or the two halves of the coupling can be made into a convex form.

The scope of application of LM type basic plum-shaped elastic coupling

1. The LM type basic plum-shaped elastic coupling 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 to achieve Automatic compensation.

3. Compared with other couplings, the plum-shaped elastic coupling has the following characteristics:

(1) Stable work, with good vibration damping, buffering and electrical insulation properties.

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

(3) It has large axial, radial and angular compensation capabilities.

(4) High-strength polyurethane elastic elements are resistant to oil, have large carrying capacity, and have long service life.

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

LM type basic plum blossom elastic coupling features: simple structure, small radial size, light weight, small moment of inertia, suitable for medium and high speed occasions, stable work, and has good vibration damping, buffering and electrical insulation properties.It has large axial, radial and angular compensation capabilities. The high-strength polyurethane elastic element is oil-resistant, has a large bearing capacity, and has a long service life. The coupling does not need lubrication, and the maintenance workload is small, and it can run continuously for a long time.The number of parts is small, the external dimensions are small, the elastic element is easy to manufacture, and the load-bearing capacity is also high. However, when assembling and disassembling, it is necessary to move the two halves of the coupling in the axial direction.

The LM type basic plum-shaped elastic coupling is mainly suitable for the transmission shaft system that is not very demanding for compensation performance and buffer reduction, especially in the transmission of medium and small power.Frequent starting, forward and reverse rotation, medium and high speed, medium torque and high requirements work occasions, such as: metallurgy, mining, petroleum, chemical industry, lifting, transportation, light industry, textile, water pump, fan, etc.The nominal torque is 25~12500N.m, the allowable speed is 15300~1900r/min, and the shaft hole diameter is 12~160mm.
