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 Couplings

■Main characteristics of Flexible Shaft Couplings
1. Strong capability to compensate for misalignment of two shafts, offering twice the angular displacement compared to Jaw couplings, lower reactionary forces during radial displacement, high flexibility, and allows for certain axial,radial, and angular displacements.
2. Provides significant vibration damping effects, operates without noise, and wear-free.
3. Can safely operate under conditions of shock and vibration.
4. High transmission efficiency, up to 99.86%, particularly suitable for medium and high-speed, high-power transmission.
5. 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 Couplings

Precautions of Flexible Shaft Couplings

■Calibration adjustment of Flexible Shaft Couplings
1. The coupling allows transmission of axis deviation, rotation angle and torque, but if the axis deviation exceeds the allowable value, vibration may occur or the lifespan will be drastically reduced. Please be sure to make corrections.
2. Axial deviation includes eccentricity (parallel error of two axes), declination (angular error of two axes), and axial amplitude (axial movement of the axes).
Perform calibration adjustment for the shaft so that the shaft center deviation is below the allowable value specified in the product dimensions and performance table.
3. The axial deviation tolerance values stated in the dimensions and performance tables refer to the situation when one of eccentricity, declination, and axial amplitude occurs individually. If two or moreaxial deviations occur simultaneously, the respective allowable values are reduced by half.
4. Axial deviation not only occurs when assembling the device, but is also a major cause of vibration, thermal expansion, and bearing wear during operation.
It is recommended that the axis deviation be set to less than 1/3 of the allowable value.
