Star-shaped (shaped) elastic coupling

　　Star elastic coupling,Star elastic couplingPolyurethane plastic is an elastic element, which has the advantages of cushioning, shock absorption, wear resistance, convenient disassembly and assembly, and the working temperature is -35~+80 degrees.It can be interchanged with West German ROTEX coupling.The polyurethane elastomer is limited 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 teeth will not wear or deform.
Star-shaped elastic coupling, the radial movement of the star-shaped elastic coupling due to the action of centrifugal force will accelerate its wear when it is running at high speed, and a shell is added.In addition to preventing dust and oil storage, insufficient thinning may cause interference. Excessive thinning will weaken the strength of the tooth, and the backlash will be large.The contact conditions of the external teeth are improved, which avoids the disadvantages of edge extrusion and stress concentration of the straight teeth under the condition of angular displacement, and at the same time improves the friction and wear of the tooth surface, reduces the noise, and has a long maintenance cycle.
Star-shaped elastic coupling, the tooth end of the outer gear sleeve of the star-shaped elastic coupling is in the shape of a horn, so it is not suitable to be used under high speed and impact load conditions, and it is not suitable for the connection of vertical shafts.Star couplingWhen designing the overall structure, pay full attention 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 a personal accident.The radius of curvature of the drum curve is proportional to the single-sided thinning of the internal teeth, that is, it is related to the meshing gap of the teeth, which makes the assembly and disassembly of the internal and external teeth very convenient.
