COUPLING
FIGURE 7–1 – INSTALLATION OF COUPLING CUSHIONS
Rotating machinery can cause
personal injury or death. Turn the unit
completely off, open the main
disconnect, tag and lockout before
servicing the coupling.
COUPLING – The motor and compressor are direct
connected by a resilient type flexible coupling with sev-
eral individual cushions. The coupling does not require
lubrication.
If maintenance on mating parts is requires, reassemble
coupling as follows:
Individual Cushion Design (FIGURE 7–1)
1.
Slide coupling halves over shaft extensions. Be
sure the collar is installed on the shaft behind one
coupling body.
2.
Assemble the motor to the compressor.
3.
Working through coverplate opening, center cou-
pling over the gap between the shafts, maintaining
the gap as shown in FIGURE 7–1 between the
ends of the jaws on one coupling body and the
flange on the opposite coupling body. Tighten set
screws in each coupling body.
4.
Insert individual cushions as shown in
FIGURE 7–1 and slide the collar over the cush-
ions and secure with cap screws. Reinstall the
cover plate.
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.
