COMPRESSOR DRIVE COUPLING
The performance and life of couplings depend
largely upon how you install and maintain them.
Before installing couplings, make certain that
foundations of equipment to be connected meet
requirements of Section 4.1. The drive coupling
must be aligned after installation and prior to ini-
tial start-up of the compressor.
The use of stainless steel shims under the motor
feet is recommended. Measuring misalignment and
positioning equipment within alignment tolerances
is simplified with an alignment computer. These cal-
culations can also be done graphically or mathe-
matically.
ANNUAL MAINTENANCE- DRIVE COUPLING
Refer to Figures 7-6,
Disconnect all power at source before attempting
maintenance or adjustments.
1. Check alignment per Step 3. If operation limits
from Table 7-1 Installation Data
realign coupling to installation limits.
2. Check outer blades of discpacks near bushings
for fatigue cracks. Discpacks can be checked
7-7 and 7-8.
are exceeded,
MAINTENANCE
while coupling is in operation by using a strobe
light. Replace cracked discpacks and recheck
alignment. A slight bowing or "S"-like distortion is
normal.
3. Check tightening torques of all drive bolts.
Standard mechanics tools, torque wrenches, a
straight edge and feeler gauges or dial indicators
and brackets and micrometers are required to
install couplings. A 17mm end wrench is required
for shrink disc locking screws. For best results use
a dial indicator to check final alignment and make
certain bolts are tightened to the required elonga-
tion or torque listed in Table 7-1 Installation
The drive bolts have been factory tightened to the
required elongation indicated in
Installation Data, and should not be disturbed.
STEP 1- HUB INSTALLATION
MOTOR HUB INSTALLATION FOR MOTOR HUB
MOUNTING
Coupling is furnished for an interference fit with a
set screw. Heat hub to 275ºF (135ºC) using an
oven, torch, induction heater or an oil bath.
To prevent damage DO NOT heat hubs beyond a
maximum temperature of 400ºF (205ºC).
When an oxy-acetylene or blow torch is used, use
Section 7
Data.
