ASSEMBLY OF COUPLING ONTO THE AIREND AND MOTOR, (See Figure 7-1).
NOTICE
Elements with non-uniform cross sections must be mounted with the rotation
arrow on the coupling the same direction as the rotation arrow on the airend.
Incorrect rotation will greatly decrease the torque carrying capacity of the
coupling.
1.
Slide coupling halves over shaft extensions. Lock compressor half (half with element pre-bolted to it)
down with set screw.
2.
Assemble the motor to the compressor.
3.
Working through the coupling guard opening, slide motor half into compressor half.
4.
Place the supplied hardened washers under the cap screw heads and torque the screws down to the
given specification. Keep the surfaces between the steel bushing in the elastomeric element, the
hardened washer and the cap screw head free from dirt and apply a light oil or grease film to both
sides of the hardened washer. This is very important since it will significantly reduce the rubber
stresses around the metal bushings when torquing down the cap screws.
5.
Check to see if element is centered between shaft ends. If element is centered, using the loctite
supplied with the coupling, lock all set screws to 50 ft-lbs. If element is not centered, unlock set
screws and slide coupling to center element between shaft ends and then, using the loctite supplied
with the coupling, lock all set screws to 50 ft-lbs.
DANGER
Rotating machinery can cause personal injury or death. Do not operate unit
with either the coupling guard or the collar removed. All bolts and screws must
be properly tightened.
ALIGNMENT
- The coupling is permanently aligned by the flanges on the compressor and motor.
Replacing Element:
NOTICE
Elements with non-uniform cross sections must be mounted with the rotation
arrow on the coupling the same direction as the rotation arrow on the airend.
Incorrect rotation will greatly decrease the torque carrying capacity of the
coupling.
1. Remove cap screws and washers.
2. Remove the element between the hubs.
