Disassembly and Reassembly of the B-Axis Speed
Reducer
• Refer to
fig. 6-5(a) “Disassembly and Reassembly of the B-Axis
.
Disassembly
1. Turn OFF the power supply of the YRC1000 with the flange surface of
the tip of the manipulator pointing down.
2. Unscrew the hexagon socket head cap screws
and
, and then
remove the flange
. If the flange surface of the tip of the manipulator
cannot be pointed down, the B-axis will rotate when the hexagon
socket head cap screws
and
are removed. Fix the B-axis so
that it will not rotate before removing the hexagon socket head cap
screws
and .
3. Unscrew the hexagon socket head cap screws
, and then remove
the speed reducer
. Be careful as grease will come out.
4. Unscrew the hexagon socket head cap screws
, and then remove
the gear and shim from the speed reducer
.
Reassembly
1. Mount the gear and shim on the speed reducer
, and then tighten
the hexagon socket head cap screws
with the tightening torque
shown in
. (Refer to
fig. 6-5(b) “Adjustment of B-Axis Gear
2. Apply ThreeBond 1206C to the contact surface of the speed reducer
and the wrist unit, and then mount the speed reducer
on the
wrist unit. For the place to apply sealing bond, refer to
“Surface to Apply Sealing Bond on the B-Axis Speed Reducer”
3. Tighten the hexagon socket head cap screws
with the tightening
torque shown in
table 6-5 “B-Axis Speed Reducer Parts Checklist”
4. Apply ThreeBond 1206C to the contact surface of the speed reducer
and the flange
, and then mount the flange
on the speed
reducer
. For the place to apply sealing bond, refer to
5. Tighten the hexagon socket head cap screws
with the tightening
torque shown in
6. Tighten the hexagon socket head cap screws
with the tightening
torque shown in
7. Replenish grease (Molywhite RE No.00) from the grease inlet. Mount
the hexagon socket head plugs at grease inlets and the grease
exhaust ports after the replenishment of grease. (Refer to
chapter 4.1.2 “Grease Exchange Procedure”
(B-axis, T-axis, and
gears).)
8. Turn ON the power supply of the YRC1000.
