Product Overview of Flexible Shaft Couplings
1. Flexible Shaft Couplings is made of several sets of discs (stainless steel sheet) bolted staggered with two coupling halves, each set of discs by several pieces of stacked set.
2. The Flexible Shaft Couplings relies on the elastic deformation of the disc to compensate for the relative displacement of the two shafts connected, is a high-performance flexible coupling with strong metal components.
3. It is characterized by compact structure, zero backlash, high strength, long service life, no rotating clearance, unaffected by temperature and oil, acid and alkali resistant and corrosion resistant.
4. Applicable motor types: Recommended for servo motors, stepper motors and general motors.

Product Features of Flexible Shaft Couplings
■ Main characteristics of Flexible Shaft Couplings
1. Flexible Shaft Couplings has 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. Flexible Shaft Couplings has provides significant vibration damping effects, operates without noise, and wear-free.
3. Flexible Shaft Couplings can safely operate under conditions of shock and vibration.
4. Flexible Shaft Couplings has high transmission efficiency, up to 99.86%, particularly suitable for medium and high-speed, high-power transmission.
5. 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.

Precautions of Flexible Shaft Couplings
■ Calibration adjustment of 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.
