What are the classification characteristics and applications of coupling sleeves?

Coupling sleeve is a commonly used accessory in couplings, and there are many types of it. So, what is a rigid coupling? What are the classification characteristics and use of coupling sleeves? The following is The editor brings content about it, hoping to make us have a harvest!

Brief introduction of rigid coupling

Rigid couplings are justified. In practice, they are couplings that change the rigidity. There is no reversal gap even when the load is received. Even when there is an error in the load, the rigid coupling still transmits torque rigidly.If there is any error in the system, it will cause premature damage to the shaft, bearing or coupling, which means that it cannot be used in a high-speed environment because it cannot compensate for the relative displacement between the shafts caused by high-speed operation.Of course, if the relative displacement can be successfully controlled, the rigid coupling can also perform very well in the use of the servo system.In particular, the small standard rigid coupling has the advantages of light weight, ultra-low inertia and high sensitivity, and in practical use, the rigid coupling has the advantages of protection-free, super oil resistance and corrosion resistance.

Rigid couplings include flange couplings and clamp couplings.

Flange coupling is the use of bolts to connect two flanged disc type half couplings, also known as flange couplings, which are generally used for shaft transmissions with stable load, high speed or high transmission accuracy.The flange coupling does not have radial, axial and angular compensation functions. If the alignment accuracy of the two connected shafts cannot be ensured during use, the service life, transmission accuracy and transmission power of the coupling will be reduced, and oscillations will be caused. And noise.

The clamp shell coupling uses two clamp shells split along the axial direction, which are clamped by bolts to complete the connection of the two shafts. The torque is transmitted by the friction between the two halves of the coupling, and the flat key is used as an auxiliary connection.

Although people did not approve the use of rigid couplings in servo transmissions in the past, because of their high torque receiving force, rigidity and zero clearance function, small standard aluminum alloy rigid couplings are increasingly used in the field of motion control. .

The rigid coupling is composed of rigid force transmission parts, and the connecting parts cannot move relative to each other. Therefore, it does not have the ability to compensate the relative deviation of the two axes. It is only suitable for the strict centering of the connected two shafts during installation. When there is no relative deviation of the two shafts, the rigid coupling has no elastic components, and the two halves of the coupling are directly connected by bolts, and do not have the function of damping and buffering. Generally, it is only suitable for working conditions with stable load and no shock condition.

Features of rigid couplings: rigid couplings are light in weight, have low inertia and are extremely sensitive. In practical use, rigid couplings are simple to protect and are resistant to oil and corrosion.And in a high-speed environment, it can compensate for the relative displacement caused by high-speed operation.Of course, if the relative displacement can be successfully controlled, it can also perform very well in the servo system.

The structure method of the rigid coupling: The rigid coupling is composed of two half couplings with grooves on the end faces and a center plate with convex teeth on both sides. Because the convex teeth can slide in the grooves, Therefore, it can compensate the relative displacement between the two shafts during the device and operation. The rigid coupling also has two shaft sleeves and a central steel shell, between which the central steel shell is a torque transmission element.The above is the little common sense about rigid couplings that I shared with us. I hope to help users who are confused in this regard. If you have any questions, please contact our factory and we will find a way to help you deal with it.

Rigid coupling (1) Light weight, ultra-low inertia and high sensitivity; (2) Free of protection, super oil and corrosion resistance; (3) Misalignment cannot be tolerated, and the shaft should be exposed as much as possible when using it; (4) ) The main material can be aluminum alloy/stainless steel; (5) Fixing methods include clamping and top wire fixing.
