(1) Confirm if any torque or axial direction load does not act on
the coupling. Torque may be applied to the coupling when a
safety break control system is activated. Make sure no torque
is applied to the coupling.
In the tapered shaft fastening method that tightens the
pressure bolts from the axial direction, the sleeve has a self-
locking mechanism so that loosening the bolts does not
release locking of the flange hub and shaft. (In some cases,
locking force could be released by just loosening the pressure
bolts.) Therefore, a space for inserting a dismounting screw
must be considered in the coupling design phase.
(3) Remove three pressure bolts loosened in (2) (two bolts for
the sizes 070 and 080 of SFF model) and insert them into the
screw bores for dismounting located on the sleeve. Tighten
them alternately little by little. Locking of the flange hub and
shaft will be released
For the SFM model, hexagon socket head cap screws are
used as its pressure bolt. Therefore, a space for L wrench
must be considered in the design phase. If there is not a
space in the axial direction, insert a flat-head screwdriver into
the A part and tap in a direction perpendicular to the shaft, or
use the principle of leverage to release locking. At this time,
take extra care not to damage the coupling or pressure bolt.
(2) Loosen all the bolts pressurizing the sleeve. For the SFM
model, loosen the bolts about 2mm from the sleeve edge. For
the SFF model, loosen the bolts about 2mm from the bearing
surface.
