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.
