Coupling Product Overview
The disc Coupling relies on the elastic deformation of the disc to compensate for the relative displacement of the connected two shafts, which is a high-performance flexible Coupling with strong metal components.
It is characterized by compact structure, no backlash, high strength, long service life, no rotation clearance, no influence of temperature and oil pollution, acid resistance, alkali resistance and corrosion resistance.
Applicable motor types: recommended for servo motors, stepping motors and general motors.
Coupling Product Feature
1. Strong ability to compensate for misalignment between two axes. Compared with tooth Coupling, angular displacement can be doubled. In case of radial displacement, reaction force is small, flexibility is large, and certain axial, radial and angular displacements are allowed.
2. It has obvious shock absorption, no noise and no wear.
3. Suitable for working in high temperature (-80+300) and harsh environment, and operate safely under shock and vibration conditions.
4. High transmission efficiency, up to 99.86%. Especially suitable for medium, high speed and high power transmission.
5. Simple structure, light weight, small in size and convenient assembly and disassembly. It can be assembled and disassembled without moving the machine (models with intermediate shaft), and requiring no lubrication.
6. It can accurately transmit the rotational speed without slip, and can be used for transmission of precision machinery

Coupling Precautions
1. The Coupling allows axis deviation, and transmits rotation angle and torque, but when the axis deviation exceeds the allowable value, vibration will occur or the service life will be drastically reduced.
Be sure to make calibration and adjustment.
2. Axis deviation includes lateral misalignment (parallel error of two axes), angular misalignment (angular error of two axes) and axial amplitude (axial movement of shaft).
Please calibrate and adjust the shaft to ensure that the axis deviation is below the allowable value recorded in the dimension and performance table of each product.
3. The allowable value of axis deviation recorded in the dimension and performance table refers to the situation when either lateral misalignment, angular misalignment or axial amplitude occurs alone. When more than two axis deviations occur at the same time, the corresponding allowable values are halved respectively.
4. Axis deviation not only occurs when assembling to the device, but also is caused by vibration, thermal expansion and bearing wear in operation. Therefore, it is recommended to set the axis deviation below 1/3 of the allowable value.
Example of Use Coupling
Coupling Usage Method
STEP1 Insert the Coupling
Confirm that the clamping bolt has been unscrewed, and then remove the dust, foreign matter and oil from the shaft and Coupling bore.
Then, when inserting the Coupling into the shaft, please be careful not to put the disc under excessive stress such as compression or tension.
STEP2 Use fixture to adjust
Please use fixture to adjust and fix the concentricity of the left and right hubs of the Coupling with high accuracy.
STEP3 Simple lateral misalignment and angular misalignment confirmation
Under the condition of unscrewed bolts, make the Coupling slide axially and confirm its smooth movement.
Then, rotate the Coupling to make sure it moves smoothly.
Lateral misalignment is not allowed for single disc type Coupling, so carry out positioning securely.
STEP4 Installation
Please adjust the shaft insertion amount according to the dimension ℓ in the product catalog, and use a torque wrench to tighten with the specified torque.
＊ If the specified torque cannot be reached once, please cross fasten the left and right clamps twice or three times.

Frequently asked question (FAQ)
- Question: Which disc type coupling is better, single disc type or double disc type?
-
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: Abnormal sound or vibration occurs during use of disc type coupling.
-
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. - Question: How to select according to the purpose, environment, working conditions?
- Answer: Please refer to the MISUMI website.
- Question: What is a coupling?
- 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: The coupling is damaged in use.
-
Answer:
Whether it is within the allowable axis deviation during use
Please note that when multiple axis deviations occur at the same time, their allowable values are reduced to 1/2 of that described in the product catalog.
