The cross shaft type universal coupling is one of the most commonly used couplings.
Using its structural characteristics, it can make two shafts that are not in the same axis or have large axial folds or large axial movements rotate continuously at equal angular speeds, and reliably transmit torque and motion.
Can be widely used in lifting, engineering transportation, mining, petroleum, shipping, coal, rubber, paper machinery and other heavy machinery industry in the mechanical shaft system to transfer torque.
The permissible rotational speed range of the cross shaft type universal coupling is based on the permissible linear speed of different materials of the universal coupling and large-scale machinery and equipment to adjust the alignment of the two shafts is more difficult to reduce the torsional vibration stress on the shaft section.
Can absorb and reduce the output torque fluctuations of diesel engines, diesel engine power units equipped with reduction gearboxes, can reduce the change in torque on the gear surface knocking, should choose to use durable and easy to replace wear parts coupling.
Metal elastic element flexible coupling is generally longer than the service life of non-metallic elastic element flexible coupling.
Need to seal lubrication and the use of non-durable cross shaft type universal coupling, is bound to increase the maintenance workload.
For long-term continuous operation and high economic efficiency of the occasion, the international industrialized countries, has been the ordinary choice of long service life, without lubrication and maintenance of the diaphragm coupling to replace the drum tooth coupling, not only improve the economic efficiency, but also can purify the working environment.
With good damping characteristics, can absorb part of the vibration energy, reduce the vibration amplitude through the vibration point, to extend the service life of the gear.
