Star Elastic Coupling

The star-shaped elastic coupling, utilizes a star-shaped elastic element placed between the two coupling halves of the dog, for elastic coupling of half couplings. The transmission shaft system connecting two coaxial lines, has the functions of compensating the relative offset of the two shafts, cushioning, shock absorption, performance, no lubrication, and can work under the condition of dust and moisture. One half of the coupling and the host shaft need to be moved to remove the components. Suitable for a wide range of occasions, the transmission torque is 20-35000.N.M, the working temperature is -35~+80 degrees, and it is interchangeable with the German ROTEX coupling. The polyurethane elastic body is limited by the convex claw block, which can avoid the internal deformation caused by the impact and the external deformation caused by the centrifugal force, the large concave surface of the convex claw makes the surface pressure on the involute teeth very small, even if the teeth are overloaded, the teeth will still not wear or deform. It has the characteristics of compensating the relative offset of the two shafts, vibration reduction, buffering, small radial size, high bearing capacity, and convenient maintenance. However, the two halves of the coupling need to move axially when replacing the elastic element. It is suitable for connecting two coaxial lines, frequent starting, positive and negative changes, medium and low speed, medium and small power transmission shafting, and working parts that require good performance. It is not suitable for heavy loads and limited axial dimensions, after replacing elastic elements the difficult part to align the two axes.


Application Scope and Performance Characteristics of Star Elastic Coupling

1. The LX series star-shaped elastic coupling is mainly composed of two convex teeth that are closely meshed and subjected to radial extrusion to transmit torque. When the two axes deviate relative to each other, the elastic element will undergo corresponding elastic deformation to automatically compensate.

2. The star-shaped elastic coupling is mainly suitable for frequent starting, positive and negative rotation, medium and high speed, medium torque and reliable work occasions, such as: metallurgy, mining, petroleum, chemical industry, lifting, transportation, light industry, Textiles, water pumps, fans, etc. The working environment temperature is -35℃~+80℃, the transmission nominal torque is 20~35000Nm, and the allowable speed is 1500~15300r/min.

3. Compared with other couplings, the star elastic coupling has the following characteristics:

a. The work is stable and excellent, and has good vibration reduction, buffering and electrical insulation properties.

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

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

d. The relatively high-strength polyurethane elastic element has stable performance, oil resistance, large bearing capacity, long service life and good performance.

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