    Tips: Why do you need a shaft coupling?

    1. Rotational power transmission
    The core function of the coupling is to transmit the power and movement of the drive shaft (motor) to the driven shaft.

    2. Absorb the deviation between the driving shaft and the driven shaft.
    The installation deviation between the driving shaft and the driven shaft is a part that is inevitably produced according to the tolerance of the mechanical elements, the accuracy and the proficiency of the operator. Deviation is divided into deflection, eccentricity, and axial deviation, which will cause vibration, noise and load of related mechanical elements. The coupling plays a role in absorbing these deviations. However, the performance of each coupling to absorb the deviation value is different, please refer to the specification and performance table.

    3. Shock, vibration and noise absorption
    When the equipment is driven, vibration and shock are generated. At this time, the shock is directly transmitted to the motor, reducer or screw, which will not only cause mechanical performance problems, but also cause high-priced parts to be repaired. The coupling plays a role in absorbing these shocks and vibrations. All types of couplings except high rigidity have the function of absorbing shock, vibration and noise. Relatively speaking, the absorption capacity of a rubber coupling with a cushioning function in the intermediate body will be better.

    4. Cut off the heat and micro current generated on the drive shaft
    The motor will generate heat if it is operated for a long time, and occasionally emit a small current. When it is transmitted to the driven shaft, thermal expansion (deformation) of the parts will occur, resulting in a decrease in accuracy. The coupling acts to cut off the heat and current generated on the drive shaft.

    5. Improve equipment performance
    In terms of vibration-proof rubber coupling, it has excellent shock absorption performance, which can relatively increase the gain value of the servo motor, shorten the setting time and improve the efficiency of the equipment.
