Maximize Performance And Life
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 manufacturers’ requirements.
Check for soft foot. The use of stainless steel shims is
recommended. Measuring misalignment and positioning
equipment within alignment tolerances is simplified with an
alignment computer. These calculations can also be done
graphically or mathematically.
Alignment is shown using spacer bar and straight
edge. This practice has proven to be adequate for
many industrial applications. However, for superior final
alignment, the use of dial indicators (see Manual 458-834
for instructions), lasers, alignment computers or graphical
analysis is recommended.
1— Mount Seals And Hubs
Lock out starting switch of prime mover. Clean all metal
parts using a non-flammable solvent. Lightly coat seals
with grease and place on shafts BEFORE mounting hubs.
Heat hubs as previously instructed. Seal keyways to
prevent leakage. Mount hubs on their respective shafts
so the hub face is flush with the end of its shaft unless
otherwise indicated.
2 — Gap and Angular Alignment
Use a spacer bar equal in thickness to the gap specified
in Table 1, Page 5. Insert bar as shown above, to same
depth at 90° intervals and measure clearance between bar
and hub face with feelers. The difference in minimum and
maximum measurements must not exceed the ANGULAR
INSTALLATION limits specified in Table 1.
3 — Offset Alignment
Align so that a straight edge rests squarely (or within the
limits specified in Table 1) on both hubs as shown above
and also at 90° intervals. Check with feelers. The clearance
must not exceed the PARALLEL OFFSET installation limits
specified in Table 1. Tighten all foundation bolts and repeat
Steps 2 and 3. Realign coupling if necessary. NOTE: Use a
dial indicator for more accurate alignment.
4 — Insert Grid
Pack gap and grooves with specified lubricant before
inserting grid. When grids are furnished in two or more
segments, install them so that all cut ends extend in the
same direction (as detailed in the exploded view picture
above); this will assure correct grid contact with non-
rotating pin in cover halves. Spread the grid slightly to pass
over the coupling teeth and seat with a soft mallet.
