JSB type axial mounting coupling

The main structure of the J-type serpentine spring coupling is composed of two half couplings, two half outer covers, two sealing rings and serpentine spring plates.It transfers torque by embedding the serpentine spring into the tooth grooves of the two coupling halves, and the coupling uses serpentine springs to be embedded in the tooth grooves of the two coupling halves to realize the link between the driving shaft and the driven shaft.During operation, the driven end is driven to transmit torque by the axial force of the active end tooth facing the snake spring, which largely avoids the occurrence of resonance and the elastic variables generated by the reed when transmitting torque. The mechanical system can obtain a better damping effect, with an average damping rate of more than 36%.

The J-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 J-type serpentine spring coupling is mainly used in rock crushers, crank reciprocating motion, reducers, metallurgy, mining, cranes and other equipment. It has compensation for medium and high power transmission shafts connecting two coaxial lines. The relative offset of the two shafts and the performance of damping and cushioning, the working temperature is -30℃~+150℃, and the transmission nominal torque is 45~800000N.m.

The J-type serpentine spring coupling is a structured metal elastic coupling.It uses a serpentine spring sheet to axially embed the two halves of the serpentine spring coupling in the tooth groove to realize the connection between the prime mover and the working machine. Resonance phenomenon, the service life is much longer than the non-metal elastic element coupling; the tooth surface contacted by the reed is arc-shaped, and the size of the contact surface changes with the size of the transmitted torque, so it can withstand large load changes. It is determined that its short-term overload capacity is 2 to 3 times the rated torque, and the transmission efficiency is 99%. It is operated; and the serpentine spring coupling has a simple structure, convenient assembly and disassembly, and allows large installation deviations. It is suitable for Impact coal crushers, rock crushers, reciprocating cranks, mines, heavy machinery, reducers, etc.
