HUB
ATTACHMENT
TO
THE
SHAFT
– BORE
AND
KEYWAY
1. Inspect
the
shaft,
hub
bores,
and
keyways
to
make
sure
that
they
are
clean
and
free
of
burrs.
Lightly
oiling
the
shaft
will
make
it
easier
to
assemble
the
hub
on
the
shaft.
2. Place
the
hub
on
the
shaft.
Be
sure
to
slide
the
hub
far
enough
onto
the
shaft
so
the
shaft
end
is
even
with
the
hub
face.
This
should
not
be
changed
without
consulting
Reich
USA
Corp.
The
distance
between
shaft
ends
(DBSE)
will
then
be
the
width
of
the
recommended
space
between
the
assembled
coupling
halves
for
the
HBSX
‐
RH
configuration
(see
dimension
L2
in
Figure
1
and
Table
1).
3. Standard
hubs
are
supplied
with
a
slight
clearance
fit.
It
is
recommended
for
hubs
with
bores
larger
than
3”
(76mm),
using
an
interference
fit
or
special
torque
transmitting
locking
devices.
For
hubs
with
interference
fits,
uniformly
heat
the
hub
to
a
maximum
of
248
– 266
o
F
(120
‐
130°C)
and
quickly
assemble
on
the
shafts.
The
use
of
torches
or
rosebuds
is
not
recommended
because
this
can
cause
high
stresses
and
permanent
distortions.
4. Fit
the
key
into
the
hub.
If
supplied
with
a
set
screw,
turn
the
set
screw
until
the
top
of
the
key
is
contacted
in
the
hub.
5. After
following
the
coupling
instructions
for
axial
alignment,
use
the
correct
‘Hub
Installation
instructions’
for
the
second
hub.
Reich
USA
recommends
starting
the
coupling
assembly
by
mounting
the
hubs
and/or
adapters
that
are
bolted
to
the
center
spacer
assembly
onto
the
input
and
output
shafts
first.
Most
of
the
time
this
will
provide
accurate
perpendicular
and
concentric
surfaces
for
aligning
the
parts
connected
by
the
R
‐
Flex
coupling.
For
standard
bore
and
keyway
hubs,
the
hubs
have
to
be
assembled
so
that
the
hub
flange
face
is
aligned
with
the
shaft
end.
The
distance
between
shaft
ends
(DBSE)
will
then
be
the
width
of
the
recommended
space
between
the
assembled
coupling
halves
for
the
HBSX
‐
RH
configuration
(see
dimension
L2
in
Figure
1
and
Table
1).
