Lubrication Jobs
Apply the specified lubricants to the rotary sections and slideways of the robot unit as listed below every three months.
| No. | Lubrication points | Lubricant type | Lubricant amount |
|---|---|---|---|
| 1 | X-axis rail | Epinoc AP1 | 2 to 3 cc |
| 2 | Z-axis rail and rack | Epinoc AP1 | 2 to 3 cc |
Grease Feeding Method for X-axis Rail
Please contact your DENSO representative for more details of grease feeding.
Grease Feeding Method for Z-axis (rail, rack)
When applying grease to the Z-axis rack of the XR series, follow the instructions for the lubrication points, amount of grease, and greasing procedure correctly. Otherwise, grease oil may drop.
Confirm that the Z-axis brake is activated before starting lubrication.
Greasing Procedure
Move the Z-axis shaft to the lowermost position and apply grease to the lubrication points specified below.
For robots with the stroke of 135 mm, move the Z-axis shaft also to the uppermost position and apply grease.
Applying grease to points other than the specified lubrication points may drop grease oil.
| Amount of grease | Lubrication points | |
|---|---|---|
| Rack | 1.0 to 1.3 g | Half of rack tooth surface (See the above figure.) |
| LM rails | 0.5 to 1.0 g per rail | Uniformly and wholly |
Move the Z-axis several times, and then wipe the residual grease off of the lower end of the LM rail.
Checking for Oil Drops
Check that there are no oil drops on the bottom of the shaft shown below. Improper environment, amount of grease, or lubrication procedure may cause oil drops.
