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 the allowable value.
