6.1
Disassembly and Reassembly of the S-Axis Speed
Reducer
• Refer to
fig. 6-1(a) “Disassembly and Reassembly of the S-Axis
.
Disassembly
1. Turn OFF the power supply of the YRC1000.
2. Disconnect the internal wiring harness from the S-head.
(Refer to
3. Remove the S-axis motor
, and then remove the input gear
.
(Refer to
chapter 5.1 “Disassembly and Reassembly of the S-Axis
.)
If the S-head is removed without removing the S-axis motor, an
external force will be applied to the shaft of the motor, causing the
shaft to bend or causing damage to the motor.
4. Unscrew the hexagon socket head cap screws
and
. Lift up the
upper part of the manipulator including the S-head, and put it down
next to the base. If there is a risk of damaging the S-axis mechanical
stoppers
and
when doing this, remove them beforehand.
5. Remove the parallel pin
.
6. Unscrew the hexagon socket head cap screws
, and then remove
the speed reducer
from the base.
7. Remove the union
from the speed reducer
.
Reassembly
1. Mount the union
on the speed reducer
. Wrap the seal tape
TB4501 around the thread part of the union
.
2. Mount the speed reducer
on the base.
3. Tighten the hexagon socket head cap screws
with the tightening
torque shown in
table 6-1 “S-Axis Speed Reducer Parts Checklist”
4. Mount the parallel pin
on the speed reducer
.
5. Apply ThreeBond 1206C to the contact surface of the speed reducer
and the S-head, and then place the upper part of the manipulator
including the S-head on the speed reducer
. For the place to apply
sealing bond, refer to
fig. 6-1(b) “Surface to Apply Sealing Bond on
NOTE
When replacing the S-, L-, and U-axis speed reducers, dis-
connect the internal wiring harness. For the procedure,
