The XL star flexible coupling is a medium-power torsion flexible coupling with shock absorption and eccentricity tolerance. It is widely used in compressors, generator sets, pumps, hoisting machinery, etc.
The elastic elements in the LX (XL) series of star-shaped elastic couplings are engineering plastics. Because the engineering plastics have good elasticity, cushioning, shock absorption, and wear resistance, they can well compensate for one of the two drive shafts. The various displacements between the two, the use occasions are common, the transmission torque is 20-35000.NM, the working temperature is -35-+80 degrees Celsius, and it is interchangeable with the German ROTEX coupling.The polyurethane elastomer of the star coupling is restricted by the convex claw block, which can avoid internal deformation caused by impact and external deformation caused by centrifugal force; the large concave surface of the convex claw makes the surface pressure on the involute tooth very small , Even if the tooth is overloaded, the tooth will not wear or deform.
The standard of LX (XL) star elastic coupling is JB/T 10466-2004
