ASSEMBLY OF COUPLING ONTO THE AIREND AND MOTOR
Figure 7-2
– INSTALLATION OF COUPLING CUSHIONS
1.
Slide coupling halves over shaft extensions. Lock compressor half down with set screw.
2.
Assemble the motor to the compressor.
3.
Working through the coupling guard opening, slide motor half into compressor half.
*
After engaging each hub on the matching recesses of the coupling element, check that the gap
between the hub flats (see dimension “E” on Figure 8-2) is within 1.10/1.19 in (28.0/30.1 mm).
A smaller gap will produce abnormal wear of the element by friction and excessive thermal
expansion
– the latter could cause compressor damage by axially displacing the input shaft. Make
sure that keys are in proper alignment with key-ways on hubs.
*
Apply a thread-locking compound to the hub setscrews (M8 size) and tighten to 7.4 lb-ft (10 N-m)
of torque. Reinstall coupling guard with provided fasteners.
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.
