EMER-FLEX
Installing NES Series couplings
1. Installing the Coupling
Read the instruction manual carefully to understand the proper method of handling couplings. Since NES Series EMER-FLEX couplings are
delivered as a completed assembly (finished bore), the coupling can be directly mounted to your equipment. Mount the coupling to the shaft
according to the following procedure.
When mounting the coupling, be careful not to apply excess force to the coupling, and be sure not to drop the coupling. Never loosen the hexagon
socket head bolt that fastens the disk.
2. Mounting the Coupling to a Shaft
① Use a cloth to wipe any dust and oil completely off the surface of the target shaft and the coupling mounting surface.
② Perform the shaft centering adjustment procedure and mount the coupling to the shaft.
The allowable angular misalignment, allowable parallel misalignment and allowable axial displacement all act in correlation to each other. When
one increases, the others decrease. These factors must, therefore, be considered together. Perform the centering adjustment while referring to the
following instructions.
<When Using the Spacer Type>
Convert the parallel misalignment into an angular misalignment (Graph 1).
Apply the total of the converted value and angular misalignment to the angular misalignment shown in Graph 2.
Adjust the centering condition so that the misalignment does not exceed the range specified for each size.
<When Using the Single Type>
The capacity of the Single Type Coupling to absorb a parallel misalignment is extremely small. Therefore, the centering adjustment should be
conducted mainly to correct any angular misalignment and axial displacement.
Graph 3 shows the correlation between the coupling’s allowable angular
misalignment and allowable axial displacement.
Adjust the centering condition so that the misalignment does not exceed the
range specified for each size.
③ Make sure that the mounted coupling can be moved in the rotating and axial
directions with only a light force when the clamp bolt is loosened. If the coupling
cannot be moved smoothly, re-adjust the centering condition in Step ② .
④
Tighten the clamp bolt with the torque specified in Table 5.
Then, insert the shaft all the way until it reaches the clamp hub end face.
