JSJ (connected with intermediate shaft) Grid coupling is a metal elastic coupling with advanced structure. The connection between the prime mover and the working machine is realized by embedding the serpentine spring axially into the tooth slots of the two halves of the coupling. Because of the special properties of the spring, the resonance between the prime mover and the working machine is largely avoided, so that the service life of the coupling is much longer than that of the coupling with nonmetallic elastic elements.
The tooth surface contacted by the spring is arc-shaped, and the size of the contact surface changes with the transmission torque, so it can bear greater load variation. It is determined that its short-time overload capacity is 2 to 3 times of rated torque, and its transmission efficiency is 99. 5%. It operation is safe and reliable; moreover, the serpentine spring coupling is simple in structure, convenient to assemble and disassemble, and allows large installation deviation. It is suitable for impact coal crusher, serpentine coupling stone crusher, crank reciprocating motion, mining, heavy machinery, speed reducer, etc.
Basic parameters and main dimensions of JSJ (connected with intermediate shaft) Grid coupling: specification JSJ1-25, nominal torque 140-800,000, shaft hole diameter 22-500, shaft hole length 48-744, weight 3.9-4686, made of cast steel. The product can also be customized according to customer requirements.
