Troubleshooting Coupling
ECHT-FLEX Coupling ※NES series is not covered.
ECHT-FLEX Coupling
1 | Disc flaps in the axial direction after the coupling is assembled. |
---|
Cause 1 | Thrust load is being applied to the coupling | Solution | Loosen the self-locking nut once, and reassemble the coupling in a state that no thrust load is applied. |
---|
2 | Vibration and noise of the coupling is a problem when using high speed rotation |
---|
Cause 1 | Need to adjust balancing after assembling the equipment. | Solution | Please specify the balance grade and rotational speed and we will consider the possibility of adjustment. |
---|
3 | Coupling is damaged |
---|
Cause 1 | The load is higher than the allowable torque. | Solution | Select the load torque to be used is less than the allowable torque in the catalog. |
---|---|---|---|
Cause 2 | Exceeding allowable misalignment | Solution | Use within the allowable misalignment range |
4 | Slips from clamp coupling area |
---|
Cause 1 | Insufficient tightening torque for clamp bolts | Solution | Check that there is no damage at the slipping area and tighten the clamp bolts to the specified tightening torque using a torque wrench |
---|---|---|---|
Cause 2 | The shaft diameter tolerance is not finished to the recommended tolerance | Solution | Keep the shaft diameter dimensions within the recommended tolerance range |
