 Reassembly
1. Apply ThreeBond 1206C to the contact surface of both sides of the
plate .
For the place to apply sealing bond, refer to "Surface to apply sealing
bond 1" in fig. 6-5(b) “Surface to Apply Sealing Bond on the R-, B-,
and T-Axis Motors” .
2. Mount the plate on the R-, B-, and T-axis motor . Mount the bigger
side of the internal chamfer of the plate on the root side of the
motor axis.
3. Mount the key on the R-, B-, and T-axis motor .
4. For the R-axis
Mount the gear unit ( , , , and inner ring of bearing ) to the
motor . Apply Loctite 243 to the thread part of the hexagon socket
head cap screw , and then tighten it with the tightening torque
shown in table 6-4 “R-, B-, and T-Axis Motor Parts Checklist” .
For the B-axis
Mount the gear on the motor . Apply LOCTITE 243 to the
thread part of the hexagon socket head cap screw , and then
tighten it with the tightening torque shown in table 6-4.
For the T-axis
Mount the gear and plate on the motor . Apply LOCTITE
243 to the thread part of the hexagon socket head cap screw , and
then tighten it with the tightening torque shown in table 6-4.
5. Apply ThreeBond 1206C to the contact surface of the R-, B-, and T-
axis motor and the casing , and then mount R-, B-, and T-axis
motor on the casing .
6. Apply ThreeBond 1206C to the thread part of the hexagon socket
head cap screws , and then tighten them with the tightening torque
shown in table 6-4.
7. Connect the encoder cable to the R-, B-, and T-axis motor , and
then tighten the connector fixing bolt (pan-head screw M2) with a
tightening torque of 0.2 N•m.
(The connector fixing bolt is provided with the connector.)
8. Insert the power connector to the R-, B-, and T-axis motor by
aligning the key position as shown in fig. 6-5(d) “Motor Power Cable” ,
and turn the coupling nut of the connector on the cable side until it
makes a clicking sound. Confirm that the arrow marks on the
connector on the motor side and the connector on the wiring harness
side match.
9. Replenish grease (Molywhite RE No.00) from the grease inlet.
(Refer to chapter 5 “Notes on Grease Replenishment/Exchange
Procedures” .)
10. Turn ON the power supply of the YRC1000.
NOTE
For removing/applying of sealing bond and assembling after
applying sealing bond, refer to chapter 5.2 “Removing,
Applying, Assembling of Sealing Bond” .
