LX type star coupling

The LX type star coupling has a working temperature of -35-+80 degrees Celsius and is interchangeable with the German ROTEX coupling. The polyurethane elastomer of the LX star coupling is restricted by the convex claw block, which can avoid the internal deformation caused by impact and the external deformation caused by centrifugal force; the large concave surface of the convex claw causes the surface pressure on the involute tooth Very small, even if the tooth is overloaded, the tooth will not wear or deform.

The LX star coupling is a high-performance coupling, which focuses on the advantages of the different structures of the standard elastic coupling, for example, it has the advantages of the plum-shaped elastic coupling: the elastic element is squeezed and the structure is simple. High sex.Overcome the shortcomings of the plum blossom elastic coupling: When changing the elastic element, move the half coupling. Although the double flange type plum blossom elastic coupling can change the element without moving the half coupling, it has a simple structure and high cost. Mass and moment of inertia, the scope of application is limited.

LX type star coupling is made of engineering plastics as elastic elements. It is suitable for connecting two coaxial transmission shafts. It has compensation for the relative deviation of the two shafts, cushioning, shock absorption, and energy. It is suitable for general occasions and transmits torque 20 -35000.NM, shaft hole 6-220mm, allowable speed 1800-19000r/min, working temperature -35-+80 degrees Celsius and interchangeable with 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.

The radial movement of the LX type star coupling due to centrifugal force will accelerate its wear when it is running at high speed, and a casing is added.In addition to preventing dust and oil, insufficient thinning may cause interference. Excessive thinning will weaken the strength of the tooth, and the backlash will be large.The contact condition of the external teeth avoids the disadvantages of squeezing the edge of the straight tooth and stress concentration under the condition of angular displacement. At the same time, the friction and wear of the tooth surface are reduced, the noise is reduced, and the maintenance cycle is long.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 for use under high speed and impact load conditions, nor for the connection of vertical shafts.When designing the overall structure of the star-shaped elastic coupling, 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 easy.
