Coupling is the imortant part in the transmission system.commonly used in the connection of two pieces with the rotary axis or shaft to transfer torque and motion,widely used in metallurgy,chemical industry,machinery,shipbuilding,electronics,aircraft and other industrial sectors.couplings are generally divided into rigid coupling and flexible shaf coupling.Due to rigid coupling of the two coaxial shafts required a high degree,flexible coupling is widely used.
*Rigid Shaft Coupling
Rigid coupling is composed of rigid componet.Applicable to two axis allowable relative displacement of little occasion.Simple sturcture,small size and low cost.Hncccoupling company produce varieties of rigid coupling flange coupling,sleeve coupling,clamp coupling,etc.
*Metal components elastic flexible shaft coupling
Metal components elastic flexible shaft coupling has the following main features:
1.Elastic elements high strength,and Smaller volume,Structure i more compact than same torque transimission shaft coupling.
2.Stable performance,long service life
3.Create more complex and costly
Metal elastic element mostly diaphragm,bellows,conecting rod,metal spring.spring snake spring,etc..
Metal elastic element coupling extensively used in:
1):With high power and high speed pumps and fans,high-power internal combustion engine,compressor,gas turbine.
2):The impact of higher torque,load changes violently broke machinery.
3):Precision mechanical transmission,data transmission systems such as CNC machine tools.
4):high temperature,high-precision drive requirements such as textile,paper,printing,packaging machinery.
*Non-metallic elastic element flexible shaft coupling
The material of Non-metallic elastic element flexible shaft coupling is rubber and import polyurethane Feature:
1.High damping characteristics,and greater ability of vibration.
2.Diverse in structure and good insulation.
3.Oil resistance and heat resistance is rather poor load performance is not stable enough
4.In operation without lubrication,easy to maintain
5.The immpact of higher torque,load changes violently broken machinery.
6.Precision mechanical transmission,data transmission systems such as CNC machine tools.
7.High temperature,high-precision drive requirements such as textile,paper,printing,packaging machinery.
