The Coupling Can Play A Safe And Protective Role

Couplings are mechanical parts that are used to connect two axes (active and driven) in different bodies to rotate together to deliver torque. In the high speed and heavy load power transmission, some couplings have the function of buffering, damping and improving the dynamic performance of the shafting. Voss Push in Couplings The coupling consists of two halves, which are connected with the active shaft and the driven shaft respectively. Most of the general engine is connected with the working machine by means of coupling.

The coupling can be divided into four categories: rigid coupling, flexible coupling, Voss Push in Couplings elastic coupling and safety coupling. Each of these categories may have several varieties.

For example: 1 elastic coupling has plum coupling, star-type coupling and other products.

2 rigid coupling has cross piece coupling, serpentine coupling and other products.

3 flexible coupling has diaphragm coupling, KL coupling and other products.

There are many kinds of 4 couplings. such as shearing pin type, steel sand type, friction type, magnetic powder type coupling. Because the safety interlock can be operated, the connection of the shaft is automatically cut off, Voss Push in Couplings so some safety couplings have the same function as the safety clutch.

Rigid couplings can only be used to join two axes with a strictly coaxial axis. and flexible couplings, due to the special structure of the design, there are many functions. As:

1, compensation due to manufacturing and installation errors caused by the joint two-axis displacement, radial displacement and angular displacement, to avoid the shaft end of the excessive load (turtle strength).

2, reduce the speed reducer work on the shaft torsional impact.

3, change the resonant speed of the shafting, for example when the impact absorption power phase. The larger the torsion angle (i.e., the smaller the stiffness), the less the impact torque. Voss Push in Couplings The lower the resonant speed. In addition, the inertia moment of the coupling also affects the resonant speed of the shaft.

4 Reduce the torsional vibration of the shaft. However, this can only be achieved if the material (such as rubber, plastics, etc.) with larger external damping (friction damping) or larger internal resistance is used as the intermediate force of the coupling.

When the machine is subjected to accidental overload, it often causes damage to the actuator or other parts. If a safety coupling is used in the transmission shaft system, the breaking, Voss Push in Couplings separating or skidding of the connecting elements in the joint sleeve can be used to break the force flow of the transmission or to restrict the transmission of the force flow.
