2.4 Shaft alignment
Parallel Alignment Tolerance (Offset): Not to exceed
0.010 inch (0.254 mm) Total Indicator Reading (0.005
inch (0.127 mm) maximum off- set).
Angular Alignment Tolerance (Gap): Not to exceed
0.0005 inch per inch (0.0005 mm/ mm) diameter at
which readings are taken (“D” on Figure 4).
Note: The alignment procedure described below has been used
successfully on many HEVC grinding mill clutch applications.
Other procedures, of course, may be used; however, the
alignment tolerances are the same regardless of
the technique used.
2.4.1 Foundations must be set so distance "X", shown
on Figure 5 (or the appropriate drawing for non
standard applications), is established. If the clutch is
mounted on a shaft having plain bearings, make sure
the shaft is centered within the bearings when
establishing the "X" dimension. Refer to Table 3 for
appropriate "X" dimensions.
Note: It is presumed that one of the shafts has been properly
located and anchored. When setting and aligning the grinding
mill drive components, always work from the pinion back
to the motor.
2.4.2 Fabricate a rigid bracket for supporting a dial indicator
and attach to the spider. See Figure 4.
2.4.3 Thoroughly clean the flange O.D. and the face of the
drum hub where alignment readings are to be taken.
2.4.4 Rotate the spider and take parallel alignment
readings off the drum hub flange O.D. If both shafts
can be rotated together, the alignment readings are
less influenced by any surface irregularities.
Note: On reverse-mounted clutches where only one shaft can be
rotated, the indicator is attached to the drum hub and readings
are taken off of the spider O.D.
Caution
When recording parallel alignment readings, “sag” of
the indicator/indicator bracket must be accounted for.
2.4.5 Angular alignment readings can be made by
accurately measuring the gap between the spider
and drum hub faces with an inside micrometer.
If a dial indicator is used, make sure to monitor and
correct for any axial movement of the shaft. To
reduce the influence any surface irregularities may
have on the angular alignment readings, index the
spider 90 degrees after taking the initial set of
readings. Take an additional set of readings and index
the spider an other 90 degrees. Continue in this
manner until four sets of readings have been taken
For misalignment correction, use the average of the
four readings at each position.
2.4.6 Shim and shift the base of the movable shaft to
correct the misalignment. After tightening the base,
recheck the alignment and correct if necessary.
Make sure to check for a “soft foot” condition.
Dowel or chock into position after satisfactory
aligment has been achieved.
Note: On some applications, thermal growth of the mill or gear
reducer (if present) may result in unacceptable shaft alignment in
a running condition. It is always a good practice to make a “hot
alignment” check and the shim if necessary.
