COUPLING – The motor and compressor are direct
connected by a flexible coupling. Style “A” coupling has
several individual cushions, (FIGURE 7–1). Style “B”
has a two piece split sleeve, (FIGURE 7–2).
Rotating machinery can cause
personal injury or death. Turn the unit
completely off, open the main
disconnect, tag and lockout before
servicing the coupling.
If maintenance on mating parts is requires, reassemble
coupling as follows:
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.
FOR STYLE “A” COUPLING:
a.
Working through the cover plate opening,
center coupling halves 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.
b.
Insert individual cushions as shown in
FIGURE 7–1 and slide the collar over the
cushions and secure with cap screws. Rein-
stall the cover plate.
FOR STYLE “B” COUPLING:
Rotating machinery can cause person-
al injury or death. Do not operate unit
with either the coupling guard or the
collar removed. All bolts and screws
must be properly tightened.
a.
Working through coverplate, center coupling
halves over the gap in the shafts. Secure
short hub half of the coupling to the shaft by
tightening the set screws over the shaft key
and 90
_
to the key.
b.
Assemble halves of split sleeve into the teeth
of the short hub half of the coupling.
c.
Slide the long hub over the split sleeve teeth
until the sleeve is bottomed in both hubs;
back long hub off 1/16 inch.
d.
Secure the long hub in position by tightening
the socket head cap screw through the split
section of the hub; tighten the set screw over
the shaft key.
Alignment – The coupling is permanently aligned by
the flanges on the compressor and motor.
