(5) Loosen about 3 turns the 2 setscrews fixing the pulse oscillator rotor to the motor shaft and
remove pulse oscillator. (Do not take off the setscrews.) However, an adhesive (TB1342H) is used
to prevent the set screws from loosening. Before removing the set screws forcibly, warm them up
to about 100°C using a thin soldering iron and then remove them.
(6) Remove the fixing screws of the pulse oscillator mount, and remove that mount. When the mount
is removed, mark the matchmarks. (For EDM22
～
EDM68, it is unnecessary to remove the pulse
oscillator mount.)
(7) Remove the V-ring. Refer to Fig. 10 for motors with
encoder only (EDM3551V and EDM3561V, EDM43 to
EDM68), and motors with encoder and electromagnetic
brake. At that time refer to Table 6 for the V-ring type
on the non-load side.
Remove the V ring.
(8) In case that the electromagnetic brake is provided,
remove it.
(9) Remove the bearing outer cover of non-load side
(since the cover of EDM35 or less is unified type with
bracket, remove the fixing bolts of the bearing inner
cover). When that outer cover is removed, mark the
matchmarks.
(10) Remove the bracket of non-load side. When it is
removed, mark the matchmarks.
(11) Remove the insulated short shaft (this shaft is attached to EDM31 or over and not attached to
EDM27 or less, of which shaft is unified type with motor shaft.) of non-load side shaft end. When
that short shaft is removed, mark the matchmarks.
(12) Remove the C-type snap ring by the pliers. (EDM35 or less)
Remove the bearing nut, bearing washer and outer slinger. (EDM43 or over)
(13) Pull out the bearing from shaft by the puller. (As to the details of replacement work of bearing,
refer to item V-2.)
(14) After completion of replacement work of bearing, carry out assembly work under reversed
procedure of disassembly. Align the matchmarks marked at the time of disassembly and tighten
the bolts of diagonal positions alternately in order to avoid uneven tightening. Also, apply grease
(Three Bond 1805 spray type) to the lip of the V ring. The shaft runout for mounting the encoder
should be 0.05 mm or less at TIR. The measurement method of shaft runout is according to Fig.11.
At that time, use a non-magnetic dial gauge. If the dial gauge is not nonmagnetic, it may not be
possible to measure shaft runout correctly.
[Note]
T.I.R.(Total Indicator Reading) refers to the total amount of dial gauge reading when the
measurement unit is rotated once around the reference axis.
