CHAPTER 5 Periodic Inspection
6 Replacing the Grease for RV Speed Reduction
Gears (R6YXX1200)
The R6YXX1200 uses RV speed reduction gears for the X and Y axes. If grease
for RV speed reduction gears deteriorates, this may shorten the service life of
RV speed reduction gears. Replace the grease periodically as explained below.
6-1 Replacement period
The grease replacement period is typically 20,000 hours of operation. However,
if the robot operation duty ratio is higher or the robot is operated in environ-
ments at higher or lower temperatures, the grease should be replaced earlier.
6-2 Recommended grease
Use the following grease.
Daphne Eponex grease EP-0 (Idemitsu Kosan) or equivalent
Replenishment grease amount (for new RV speed reduction gears)
X-axis speed reduction gear 514 cc
Y-axis speed reduction gear 192 cc
CAUTION
THE RV SPEED REDUCTION GEAR SERVICE LIFE MAY SHORTEN IF
THE GREASE RECOMMENDED BY OMRON IS NOT USED.
