ECHT-FLEX Coupling

1Disc flaps in the axial direction after the coupling is assembled.
Cause 1Thrust 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.

2Vibration and noise of the coupling is a problem when using high speed rotation
Cause 1Need to adjust balancing after assembling the equipment. Solution Please specify the balance grade and rotational speed and we will consider the possibility of adjustment.

3Coupling is damaged
Cause 1The 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 2Exceeding allowable misalignment Solution Use within the allowable misalignment range

4Slips from clamp coupling area
Cause 1Insufficient 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 2The shaft diameter tolerance is not finished to the recommended tolerance Solution Keep the shaft diameter dimensions within the recommended tolerance range
