JS type housing radial mounting type coupling

The JS-type shell radially mounted coupling belongs to a metal elastic variable-rigidity coupling with a reasonable structure, and it also belongs to a flexible coupling with elastic elements. The main structure of the JS-type shell radially mounted coupling is composed of two half couplings, two half outer covers, two sealing rings and serpentine springs.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 by the axial force of the active end tooth facing the snake spring to transmit torque, which largely avoids the resonance phenomenon, and the elastic variable generated by the reed when the torque is transmitted , So that the mechanical system can obtain a better damping effect, with an average damping rate of more than 36%.

Structural features of JS type casing radial mounting coupling:

1,Serpentine spring couplingThe structure is simple, and the assembly and disassembly are convenient.The whole machine has fewer parts, small size and light weight. The spring leaf designed as a trapezoidal cross-section and the trapezoidal tooth groove are particularly convenient and close, so that the assembly, disassembly, and maintenance are simpler than ordinary couplings.

2. High transmission efficiency and reliable operation.The coupling has high transmission efficiency, its short-term overload capacity is twice the rated torque, and it runs reliably.

3. Large range of bearing variable load.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 arc of the teeth, 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 larger load variation than general elastic couplings.The buffering effect produced by the transmission force when the reed deforms along the tooth arc, especially when the machine is started or strong impact load, to a greater extent, protects the supporting parts.

4. Low noise and good lubrication.The aluminum alloy shell protects the spring from being thrown out during operation, and the shell is filled with butter, which not only makes the lubrication good, but also makes the noise when the reeds engage is absorbed by the butter damping and eliminated.

5. Good vibration damping and long service life.The coupling is axially embedded in the tooth grooves of the two coupling halves with a serpentine spring sheet, and torque is transmitted through the tooth grooves of the embedded two halves of the coupling.The serpentine spring plate is made of spring steel, subjected to strict heat treatment and special processing. It 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 coupling). , Nylon rod-pin couplings) greatly increased.

6. Large 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.
