Star elastic coupling
The star elastic coupling is made of engineering plastic as an elastic element, suitable for connecting the two coaxial axes of the transmission shaft system, with compensation for the relative offset of the two axes, cushioning, shock absorption, wear resistance, to adapt to the common occasions, transfer torque 20-35000.N.M, working temperature -35-+80 degrees Celsius and the German ROTEX coupling exchange. The polyurethane elastomer is confined by a convex claw.
Structural characteristics:
Compact size and low inertia
Materials used for coupling:
Cast iron, 45 steel, forged steel, aluminum alloy.
Transmission shafting:
Star elastic coupling polyurethane elastomer is limited by convex claw, the coupling is made of engineering plastics as elastic components, suitable for connecting two coaxial axes of the transmission shaft system, with compensation for two axes relative offset, cushioning, shock absorption, wear resistance, suitable for common occasions, Transfer torque 20-35,000.n.m, operating temperature -35-+80 degrees Celsius and interchangeable with German ROTEX coupling. The elastic element in the XLD star elastic coupling is engineering plastic. Because the engineering plastic has good elasticity, cushioning, shock absorption and wear resistance, it can compensate various displacements between the two transmission shafting well. The polyurethane elastomer of the star elastic coupling is confined by a convex claw. Features: No backlash connection under prestress, used for spindle drive, lifting platform and machine tools.
Intensity
- The radial motion caused by the centrifugal force will accelerate the wear of the star elastic coupling when it is running at high speed. In addition to dust and oil storage, insufficient thinning may cause interference, and too much thinning will weaken the strength of the teeth, and the side backlash will be large. The contact condition of the outer teeth is improved, avoiding the disadvantages of the straight tooth end edge extrusion and stress concentration under the condition of angular displacement, and improving the friction and wear condition of the tooth surface, reducing the noise and long maintenance cycle.
- The tooth end of the outer gear sleeve of the star elastic coupling is in horn shape, so it is not suitable for use at high speed and under impact load, and it is not suitable for the connection of the vertical shaft. 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 safety protection. Because if the chain breaks, it could cause a personal accident. The radius of curvature of the drum curve is proportional to the thinning amount of the inner tooth on one side, that is, it is related to the meshing clearance of the teeth, which makes the installation and disassembly of the inner and outer teeth very convenient.
Star type elastic coupling features;
The connection without backlash under prestress is used for spindle drive, lifting platform and machine tool. The elastic elements in the XL star elastic coupling are engineering plastics, which are used in common occasions, and the transmission torque is 20-35000.N.M. The operating temperature is -35-+80 degrees Celsius and is exchanged with the German ROTEX coupling.
