• Refer to
3 “Disassembly and Reassembly of U-Axis Speed
Disassembly
1. Turn OFF the DX100 power supply, then drain grease.
2. Before removing the U-arm unit, support the U-arm unit with a chain
block, etc. to prevent it from falling.
3. Remove the hexagon socket head cap screws . Then, remove the
U-arm unit from the L-arm.
4. Remove the U-axis motor from the U-arm unit.
(Perform
“Disassembly”
section 5.3 “Disassembly and Reassembly
.)
5. Remove the GT-SA bolts , then remove the speed reducer .
6. Remove the hexagon socket head cap screw , then remove the input
gear .
7. Remove the old sealing bond on the L-arm and the U-arm unit.
Reassembly
1. Mount the input gear on the U-axis motor. (The input gear is
attached to the speed reducer . Thus, when replacing the speed
reducer , replace the input gear too.)
2. Apply Loctite 242 to the thread part of the hexagon socket head cap
screw . Then, tighten it with the tightening torque shown in
"U-Axis Speed Reducer Parts Checklist"
3. Apply ThreeBond 1206C on the matching surface between the speed
reducer and the U-arm unit. Then, mount the speed reducer on
the U-arm unit.
4. Tighten the GT-SA bolts with the tightening torque shown in
3 "U-Axis Speed Reducer Parts Checklist"
5. Mount the U-axis motor on the U-arm unit. (Perform
“Reassembly”
in
section 5.3 “Disassembly and Reassembly of U-Axis Motor”
.)
6. Apply ThreeBond 1206C on the matching surface between the speed
reducer and the L-arm. Then, mount the U-arm unit with the speed
reducer on the L-arm.
7. Tighten the hexagon socket head cap screws with the tightening
torque shown in
3 "U-Axis Speed Reducer Parts Checklist"
.
For the screws marked with , apply ThreeBond 1206C on the thread
parts of them before tightening them.
8. Replenish grease (VIGO Grease RE No.0) through the grease inlet.
9. Turn ON the DX100 power supply.
