JSB type serpentine spring coupling is abbreviated as "snake spring coupling" made according to JB/T 8869-2000 standard. Different from JS type serpentine spring coupling, JS type serpentine spring coupling is used for horizontal installation. The JSB serpentine spring coupling is used for vertical installation.
JSB type serpentine spring coupling is suitable for complex working conditions such as temperature, humidity, water, steam, dust, sand, oil, acid, alkali, corrosive medium, salt water, radiation, etc.For the working quality of high temperature, low temperature, oil, acid, alkali medium, it is not suitable to choose the flexible coupling with general rubber as the elastic element material, and should choose the flexible coupling of the metal elastic element, such as diaphragm coupling, Serpentine spring couplings, etc.
The JSB type serpentine spring coupling is mainly used in crushers, crank reciprocating motion, reducers, metallurgy, mining, cranes and other equipment. It has certain requirements for medium and high power transmission shaft systems connecting two coaxial lines Compensate the relative deviation of the two shafts and the performance of vibration reduction and cushioning. The working temperature is -30℃~+150℃, and the nominal torque is 45~800000N.m.
Features of Snake Spring Coupling:
1. Features: The serpentine spring is used as the elastic element, which has strong elasticity and greatly improves the transmission torque of the serpentine spring coupling. It is widely used in heavy machinery and general machinery.
This serpentine spring with a special process has a long service life, allows a high speed, and has good compensation capabilities in the axial, radial and angular directions.
Snake spring coupling can withstand large torque, suitable for heavy machinery and general machinery occasions
2、联轴器弹簧又名蛇形弹簧。 蛇簧联轴器扭短范围为26-270000N.M。两半轴允许相对径向位移0.5-3mm，轴向位移4-20mm,角位移1o15’。
3. High transmission efficiency and safe starting. The transmission efficiency can reach 99.47%, and the short-term overload capacity is twice the rated torque...... safe operation;
4. Simple structure; convenient disassembly and assembly, long service life;
5. Good damping effect, avoiding resonance.
