Shaanxi LXS double flange star coupling

LXS double-flange star coupling is made of engineering plastics as elastic elements, suitable for connecting two coaxial transmission shafts, with compensation for the relative deviation of the two shafts, buffering, and shock absorption, suitable for general occasions, and transmitting torque 20 -35000.NM, working temperature -35-+80 degrees Celsius and interchangeable with German ROTEX flexible coupling.

The elastic element in the LXS double-flange star coupling is engineering plastic. Because the engineering plastic has good elasticity, cushioning and shock absorption, it can well compensate for various displacements between the two drive shafts. Common use occasions, transmission torque 20-35000.NM working temperature -35-+80 degrees Celsius and interchangeable with the German ROTEX coupling.Star couplingThe polyurethane elastomer is limited 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 makes the surface pressure on the involute tooth very small, even if the tooth bears Overload, the teeth will not wear or deform.

The standard of LXS double flange star coupling is JB/T 10466-2004

LXS double flange star couplings are generally used in the following power units:

Main propulsion power unit of marine diesel engine.

Medium and high-speed diesel engine power unit equipped with reduction gearbox and clutch.

Diesel engine-generator set.

Diesel engine driven slurry pump, water pump, compressor and other power devices.

Hydraulic drive diesel locomotives, automobiles and other power plants.

Power devices such as speed reducers, rolling mills, mixers, etc. driven by electric motors or other power machinery.

According to the "multi-mass system, the torsional vibration calculation of the power plant shaft system:

After preliminary selection and determination of the star coupling model, the torsional vibration of the shaft system should be calculated for the newly built power plant. Free vibration calculation and forced vibration calculation should be used to determine the natural frequency of the shaft system and the additional stress of torsional vibration of the shaft section as well as the star Type elastic coupling bears large torque and variable torque.

For the calculation method of shafting torsional vibration, please refer to relevant literature.For the finalized and mass-produced power plant, shaft torque test and star elastic coupling dynamic performance test should be carried out to verify the correctness of the calculation.
