High-speed Shaft Axial Float Measurement
—
Ref #1A or 3A Assembly – Figure 26 Set
up a dial indicator as illustrated in Figure 26
to measure axial float of output end of shaft
Push upward on shaft extension end with a
twisting motion to obtain reading Subtract
from this reading the axial float for the Ref #1A
(or 3A) shaft assembly shown in Table 15 This
indicates the thickness of metal shim(s), Ref
#24, to be added behind the input housing
bearing cup to obtain the specified axial float
WARNING:
Cover shaft extension end keyway
with tape to avoid lacerations to the hand.
(10) Disassemble drive once more to add metal
shim(s) behind input intermediate and high-
speed housing bearing cups to obtain the
specified axial float shown in Table 15
(11) Apply a bead of Loctite 515 to input housing
flange as shown in Figure 27 Assemble output
housing to input housing and install dowels
Install and cross tighten flange fasteners to
torque specified in Table 14
(12) Check intermediate and high-speed shaft
axial floats with dial indicator to ensure they
are within specified limits If necessary,
disassemble drive Clean Loctite 515 from
housing flanges Readjust metal shims behind
input housing bearing cups, reapply Loctite
515, and reassemble Repeat until specified
float is achieved
