XLS Star Elastic Coupling

XLS star-shaped elastic coupling is made of engineering plastics as the elastic element, which is suitable for connecting two coaxial transmission shafts. It has the functions of compensating the relative offset of the two shafts, buffering, shock absorption, and can adapt to a wide range of occasions. Transmit torque:20-35000.N.M, working temperature: -35~+80 degrees. Interchangeable with German ROTEX elastic couplings.


Features of XLS Star Elastic Coupling

The elastic element in the XLS star-shaped elastic coupling is engineering plastics, because the engineering plastics have good elasticity, cushioning, and shock absorption, so they can well compensate for various displacements between the two transmission shafts. The polyurethane elastic body of the star-shaped elastic coupling 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 high Even if the teeth are overloaded, the teeth will not wear or deform. Features: backlash-free connection under prestress, used for spindle drive, lifting platform and machine tools, axial plug-in assembly, convenient for blind assembly, saving time, small size, small moment of inertia, maintenance-free, easy for visual inspection. The elastic body in the middle is made of polyurethane materials from many regions in Germany, and there are various hardness to choose from.


The radial movement of the XLS star-shaped elastic coupling due to the centrifugal force will accelerate its wear and tear when it is running, so a shell is added. In addition to being able to prevent dust and oil, insufficient thinning may cause interference, and excessive thinning will weaken the strength of the tooth and cause a large backlash. The contact condition of the external teeth avoids the disadvantages of straight tooth edge extrusion and stress concentration under the condition of angular displacement, and at the same time reduces the friction and wear of the tooth surface, reduces noise, and has a long maintenance cycle. The tooth end of the outer gear sleeve of the star-shaped elastic coupling is in the shape of a trumpet, so it is not suitable for use under high-speed and impact load conditions, nor for the connection of vertical shafts. When designing the overall structure of the star elastic coupling, full attention should be paid to the lubrication and dust prevention between the tooth surface and the roller, as well as the protective effect. Because if the chain breaks, it may cause personal accident. The radius of curvature of the bulging curve is proportional to the amount of thinning on one side of the inner teeth, that is, it is related to the meshing clearance of the teeth, which makes the inner and outer teeth easy to assemble and disassemble.
