A coupling is a part that connects two different rotating bodies (motor shaft, ball screw, etc.) and aims at transmitting torque. The load of assembly adjustment is reduced by absorbing the axis deviation (lateral misalignment, angular misalignment and axial amplitude) between rotating bodies. And in case of accidental overload, the coupling is destroyed and the rotating bodies are disconnected to protect the expensive power part and the whole device.

Which disc type coupling is better, single disc type or double disc type?

Double disc type can absorb angular misalignment and lateral misalignment, but the total length will increase. Although the total length of the single disc type is short, it is only suitable for applications with narrow space because lateral misalignment is not allowed in the structure. Special attention should be paid to centering during use.

Abnormal sound or vibration occurs during use of disc type coupling.

When a servo motor is used, the frequency of the mechanical resonance suppression filter is set as its inherent vibration frequency in the control system to suppress sound and vibration. When using a stepping motor, the rotational speed can be finely adjusted, or the vibration can be absorbed and suppressed by the high damping rubber type coupling with obvious attenuation effect.

How to achieve the effect of applicable lateral misalignment and angular misalignment in product design?

The plate spring formed by the slit allows lateral misalignment, angular misalignment and end play.

What does the product need for applications of lateral misalignment and angular misalignment?

Lateral misalignment, angular misalignment and axial amplitude are all single allowable values. If there are multiple deviations at the same time, the allowable value of each deviation will be reduced to 1/2 of the original value.

Product Features of Flexible Shaft Flexible Shaft Couplings

■ Main characteristics of Flexible Shaft Flexible Shaft Couplings
1. Flexible Shaft Flexible Shaft Couplings has strong capability to compensate for misalignment of two shafts, offering twice the angular displacement compared to Jaw Flexible Shaft Couplings, lower reactionary forces during radial displacement, high flexibility, and allows for certain axial,radial, and angular displacements.
2. Flexible Shaft Flexible Shaft Couplings has provides significant vibration damping effects, operates without noise, and wear-free.
3. Flexible Shaft Flexible Shaft Couplings can safely operate under conditions of shock and vibration.
4. Flexible Shaft Flexible Shaft Couplings has high transmission efficiency, up to 99.86%, particularly suitable for medium and high-speed, high-power transmission.
5. Flexible Shaft Flexible Shaft Couplings is simple structure, lightweight, small volume, and convenient for assembly and disassembly. Installation and removal can be done without moving the machine (refers to the type with an intermediate shaft) and does not require lubrication.
6. Can accurately transmit rotational speed, operates without slip, suitable for the transmission of precision machinery.

Example Use of Flexible Shaft Flexible Shaft Couplings

Precautions of Flexible Shaft Flexible Shaft Couplings

■ Calibration adjustment of Flexible Shaft Flexible Shaft Couplings
1. The Flexible Shaft Couplings allows shaft center deviation and transmits rotation angle and torque. However, when the shaft center deviation exceeds the allowable value, vibration will occur or the service life will be drastically reduced.
2. Axis deviation includes eccentricity (parallel error of two axes), declination (angular error of two axes), and axial amplitude (axial movement of the shaft).
Please calibrate and adjust the shaft to ensure that the axis center deviation is below the allowable value stated in the dimensions and performance table of each product.
3. The allowable value of axial misalignment stated in the dimensions and performance table refers to the situation when one of eccentricity, declination, or axial amplitude occurs alone.
When more than two axis deviations occur at the same time, the corresponding allowable values will be halved respectively.
4. Axial misalignment not only occurs when assembling to the device, but also occurs due to vibration, thermal expansion, bearing wear, etc. during operation. Therefore, it is recommended to set the axis deviation to less than 1/3 of theallowable value.

Frequently asked question (FAQ)FAQ

Question:Question: What is a coupling?: Answer:Answer: A coupling is a part that connects two different rotating bodies (motor shaft, ball screw, etc.) and aims at transmitting torque. The load of assembly adjustment is reduced by absorbing the axis deviation (lateral misalignment, angular misalignment and axial amplitude) between rotating bodies. And in case of accidental overload, the coupling is destroyed and the rotating bodies are disconnected to protect the expensive power part and the whole device.
Question:Question: Which disc type coupling is better, single disc type or double disc type?: Answer:Answer: Double disc type can absorb angular misalignment and lateral misalignment, but the total length will increase.
Although the total length of the single disc type is short, it is only suitable for applications with narrow space because lateral misalignment is not allowed in the structure.
Special attention should be paid to centering during use.
Question:Question: Abnormal sound or vibration occurs during use of disc type coupling.: Answer:Answer: When a servo motor is used, the frequency of the mechanical resonance suppression filter is set as its inherent vibration frequency in the control system to suppress sound and vibration.
When using a stepping motor, the rotational speed can be finely adjusted, or the vibration can be absorbed and suppressed by the high damping rubber type coupling with obvious attenuation effect.
