XL star-shaped elastic coupling features: connection without backlash under prestress, used for spindle drive, lifting platform and machine tool, etc.; the elastic element in XL star-shaped elastic coupling is engineering plastics, and it is widely used in transmission and rotation. Moment 20-35000.NM working temperature -35-+80 degrees Celsius and interchangeable with German ROTEX coupling.
The radial movement of the star-shaped elastic coupling due to the centrifugal force during high-speed operation will accelerate its wear, and a shell 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 conditions of the external teeth are improved, which avoids the disadvantages of edge extrusion and stress concentration of the straight teeth under angular displacement conditions, and at the same time improves 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 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 safety protection function.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.
