Hebei JS type housing radial mounting type coupling
The JS-type casing radially mounted coupling uses a serpentine spring leaf to axially embed the two halves of the coupling in the tooth groove to achieve the connection between the prime mover and the working machine. Due to the performance of the reed, it is largely Avoid the resonance phenomenon between the prime mover and the working machine, and 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 size of the transmitted torque, so it can The amount of load change it bears is determined to be 2 to 3 times the rated torque for short-term overload capacity, and the transmission efficiency reaches 99.5%.; And the structure of the serpentine spring coupling is simple, easy to assemble and disassemble, and large installation deviation is allowed. It is suitable for impact coal crushers, serpentine spring coupling stone crushers, crank reciprocating motion, mining, heavy-duty Machinery, reducer, etc.
The JS type casing radial mounting type coupling is a structured metal elastic coupling.It relies on serpentine springs to transmit torque.Its transmission characteristics and advantages are as follows:
1. The JS-type casing radial installation coupling has a simple structure and is convenient for assembly and disassembly. The whole machine has few parts, small size and light weight. The spring sheet designed as a trapezoidal cross-section and the trapezoidal tooth groove are particularly convenient and tight. It makes assembly and disassembly and maintenance easier than general couplings.
2. Large range of bearing variable load, starting, The tooth surfaces of the two half couplings in contact with the reeds are arc-shaped. When the transmission torque increases, the springs will deform along the tooth arcs, so that the force points of the two half couplings on the reeds are close.The contact point between the reed and the tooth surface, that is, the change of torque, changes with the size of the transmitted torque, and its transmission characteristics are variable stiffness.Therefore, it has a load variation that can withstand a general elastic coupling.The buffering effect produced by the transmission force when the reed deforms along the tooth arc, especially when the machine is started or impact load, to a certain extent to protect the supporting partsSex.
3. Larger installation deviation is allowed. Because the spring leaf and the tooth arc surface are in point contact, the coupling can obtain greater flexibility.It can be installed to work normally under conditions of radial, angular and axial deviations at the same time.
4. Low noise, lubricate the aluminum alloy casing to protect the spring from being thrown out during operation, and the casing is filled with butter, which not only makes the lubrication good, but also makes the noise of the reed meshing is absorbed by the butter damping.
5. Good vibration damping and long service life. The coupling is axially embedded in the two halves with a serpentine spring leaf for more than 36%.The serpentine spring sheet with trapezoidal section adoptsSpring steel, after rigorous heat treatment and processing, has good mechanical properties, so that the service life of the coupling is much longer than that of the non-metal elastic element coupling (such as elastic sleeve pin, nylon rod pin coupling) Great growth.
6. Transmission, operation, the transmission efficiency of the coupling is determined to reach 99.47%, and its short-term overload capacity is twice the rated torque..
