Universal coupling is the key equipment to save energy

Universal coupling is the key equipment to save energy. According to network media statistics, there are at least 180 million kw motors with variable load and energy saving potential in China, thus providing a huge market for the application of coupling. Coupling has been applied by common fan, water pump, etc to food, beverage, logistics, building, etc., and constantly open new energy field, its function also improved and diversification, on the one hand, is a fully digital, the function is all ready, can compensate the load change adaptive, self tuning technique, especially distributed with the communications, networking, and integrated PLC higher coupling; On the other hand is a simple or industry-specific coupling and electromechanical integration, miniaturized coupling. In addition, due to the advent of new high voltage power electronic devices, high voltage and medium voltage couplings have also made great progress. The two shafts connected by the universal coupling, due to manufacturing and installation errors, bearing deformation and the impact of temperature changes, will cause the change of the relative position of the two shafts, often can not ensure strict alignment. Coupling can be divided into rigid coupling, flexible coupling and coupling according to whether the coupling has elastic elements, whether there is compensation ability for various relative displacement, that is, whether the coupling function can be maintained under the condition of relative displacement and the purpose of the coupling.

Couplings transfer motion and torque, overload stability protection. Flexible coupling also has different degrees of compensation performance including pin type, friction type, magnetic powder type, centrifugal type, hydraulic type coupling.
