Product Description
The grid coupling is the most advanced shaft connection
transmission component in the international mechanical field, and
it is also a very general shaft connection transmission
component.The main structure of the grid coupling is composed of
two hubs, two covers, two sealing rings and grids. It relies on the
coiled grid embedded in the tooth groove of the two hubs to
transfer torque, to achieve the link between the driving shaft and
the driven shaft. In operation, the driven end is driven by the
axial force of the teeth of the active end facing the grid to
transfer the torque. In this way, the resonance phenomenon is
avoided to a large extent. Besides, the elastic variable generated
by grid when transferring the torque enables the mechanical system
to obtain better vibration damping effect.
The JS Snake Spring Grid Coupling is called the "snake spring
coupling", which belongs to a kind of flexible connection in the
coupling. JS type serpentine spring coupling on spring serpentine
to transfer torque to the coupling coupling to embedded in half
serpentine spring shaft slot, to realize the joint motor and
machine, due to the special properties of the spring, so as to
avoid the resonance phenomenon of motor and machine to a great
extent, service life is much higher than that of non metal flexible
coupling; the tooth surface contact reed is an arc, the contact
surface varies with the torque size, thus can withstand greater
load variation. Suitable for impact crusher, crusher, reducer etc..
