5.1. Grease Replenishment/Replacement
| Attention
If greasing is performed incorrectly, the internal pressure of the grease bath may suddenly increase, possibly causing damage to the seal, which would in turn lead to grease leakage and abnormal operation. When performing greasing, therefore, observe the following cautions. |
(1) Be sure to wear protective glasses before injecting and inspecting grease.
(2) Be sure to remove the grease outlet plug before injecting grease.
(3) When the plug is loosened, the grease and plug may be discharged abruptly. To prevent a discharged object from damaging any part of your body such as your face, block the outlet with a thick cloth and secure a safe distance. (Do not look into the grease outlet.)
(4) If possible, do not use a compressed air pump driven by the air supplied from the factory, and limit the grease injection pressure to 2.5 bar (2.5 kgf / cm2) or below.
(5) Use only the designated grease. Otherwise, damage to the reducer and other problems could occur.
(6) After injecting the grease, check whether the grease outlet is leaking and whether there is no pressure at the inlet before fastening the plug.
(7) To prevent accidents, clean the grease leaked onto the robot’s main body or floor.
(8) When using the robot at an ambient temperature of 35 ° C or higher, reduce the grease replenishment and replacement cycles by half.
n Procedures for replacing the grease and for removing the over-injected grease and residual pressure.
(1) Attach a grease tray or hose to the grease outlet to prevent the surroundings from being contaminated by the discharged grease.
(2) Will operate under the following conditions within the range that will not cause interference with the surroundings.
Axis | Operation angle (Axis 1/Axis 2 / Axis 3 | Playback speed | Operation time |
Axis 1 ~ Axis 3 | 80°/90°/70° or above | 50 % | 20 minutes at least |
Axis 4 ~ Axis 6 | 60°/120°/60° or above | 100 % | 20 minutes at least |
Arm gearbox | 60°/120°/60° or above | 100 % | 20 minutes at least |
(3) Wipe the outlet with a cloth and assemble the plug back into its origianl place.
n Periodic Replenishment / Replacement
Periodic Replenishment / Replacement
ü S axis reducer and the arm frame gearbox: Every 24,000 hours ü Other reducers : Every 12,000 hours ü Bearings of the gas spring : Every 6 months (Every 3 months under |
If there is still noise in the reducer even after using specified grease, check the state closely for 1-2 days during operation. Generally, the noise will go away.
(The noise will go away if you run the axis at a high speed for 5-10 minutes).
The noise may be caused by following reasons
1. Operation after greasing or replacing the reducer
2. Operation after long-term storage
3. Operation at a low speed
4. Operation at a low temperature
