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.

Is there any reference available for the selection of hole diameter at both ends of the product?

Equal diameter of d1 and d2=d1＋0.5 Unequal diameter of d1 and d2=diameter of large shaft hole+0.5

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

Flexible Shaft Couplings with zero backlash, this product is suitable for applications where rotational accuracy is required.

Precautions

■ Calibration adjustment
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 more axial deviations occursimultaneously, 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 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: Is there any reference available for the selection of hole diameter at both ends of the product?: Answer:Answer: Equal diameter of d1 and d2=d1＋0.5
Unequal diameter of d1 and d2=diameter of large shaft hole+0.5
Question:Question: How to achieve the effect of applicable lateral misalignment and angular misalignment in product design?: Answer:Answer: The plate spring formed by the slit allows lateral misalignment, angular misalignment and end play.
Question:Question: Which mechanism parts does the product apply to?: Answer:Answer: With zero backlash, it is suitable for applications where rotational accuracy is required.
Question:Question: What does the product need for applications of lateral misalignment and angular misalignment?: Answer:Answer: 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.
