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.
Installation of Spacer Assembly
1— Mount Seal & Hubs
Lock out starting switch of prime mover. Lightly coat seal with
grease and place on shaft before mounting T-Hub. Heat
interference fit hubs as previously instructed. Mount hubs on their
respective shafts so that hub face is flush with the end of the shaft
unless otherwise indicated. Allow hub to cool. Seal keyway of
T-Hub to prevent leakage. Tighten setscrew when furnished.
2 — Mount Half Spacer
Wrap tape over grid grooves and carefully stretch and roll the
seal over hub teeth into position. Remove tape. Carefully
position half spacer on register of shaft hub and fasten parts
together. Torque fasteners to specifications in Table 2 on Page
6. Position drives for approximate distance between shaft ends
with minimum angular and offset misalignment.
3 — Gap & Angular Alignment
Use a spacer bar equal in thickness to the gap specified in
Table 2 on Page 6. 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 2 on Page 6.
4 — Offset Alignment
Align so that a straight edge rests squarely (or within the limits
specified in Table 2, Page 6) 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 2 on Page 6. Tighten all foundation bolts
and repeat Steps 3 and 4. Realign coupling if necessary.
