J-type serpentine spring couplingIt is a structured metal elastic coupling. The J-type coupling uses a serpentine spring leaf to be axially embedded in the tooth grooves of the two coupling halves to realize the connection between the prime mover and the working machine. Due to the performance of the reed, the prime mover and work are largely avoided. The resonance phenomenon of the machine, the service life is much longer than that of 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 transmission torque, so it can withstand large load changes. , The short-term overload capacity is determined to be 2 to 3 times the rated torque, and the transmission efficiency reaches 99.5%. It operates; and the serpentine spring coupling has a simple structure, easy assembly and disassembly, and allows large installation deviations. It is suitable for Impact coal crusher, serpentine spring coupling rock crusher, reciprocating crank, mining, heavy machinery, reducer, etc.
