2.8.7 Mounting Axis 2 Reduction Gear
• Handle the reduction gear with extreme care. If it drops or an unusually large
external force is exerted on it, the reduction gear cannot function any further.
• Use the center gear which is attached to the new reduction gear.
If the old center gear is used as it is, abnormal noise will be caused, the service
life will shorten or positioning accuracy will deteriorate due to incompatibility
with the new reduction gear.
• Also use the “O” ring attached to the new reduction gear. Be sure to set the
“O” ring. Unless the “O” ring is set, grease will leak from the axis 2 reduction
gear set surface. When mounting the reduction gear, take careful precautions
not to break the “O” ring.
1) Mount the new reduction gear on the arm 2 with the eight (8) bolts (M6 × 55).
Before mounting the reduction gear, set the “O” ring in the “O” ring groove on
the bottom of the reduction gear.
2) Mount the center shaft on the axis 2 reduction gear with the four (4) bolts (M3 ×
8). After setting the “O” ring attached to the reduction gear in the center shaft,
secure the center shaft to the reduction gear.
