and abnormal operation. Therefore, when performing lubrication operations, please observe the
following:
1
）
Before performing the lubrication operation, open the oil drain port (remove the oil drain plug
or screw plug).
2
）
Provide lubricant slowly , the oil supply speed should be controlled below 40cc/10 seconds, do
not use too much force, you must use a lubricating gun that can clearly determine oil quantity. If
there is no oil gun that can clarify the amount of lubrication, the amount of lubricant should be
confirmed by measuring the change in the weight of the lubricant before and after refueling.
3
）
If the oil supply does not reach the required amount, you can use a precision regulator for air
supply to squeeze out the gas in the cavity and then supply the oil. When using the regulator, the
air pressure should be controlled below the maximum 0.025MPa.
4
）
Use only specified types of lubricants. If you use other lubricant other than the specified type,
it may damage the decelerator or cause other problems.
5
）
When installing the hexagon socket screw plug after the oil is supplied, pay attention to
winding the sealing tape to avoid oil leakage at the oil inlet and outlet.
6
）
In order to avoid accidents caused by slips and falls, the excess lubricant on the ground and the
robot should be completely removed.
7
）
After the oil is supplied, follow the steps in item 4.4.4 to release the residual pressure in the
lubricating oil tank and install the hexagon socket screw plug. Pay attention to winding the sealing
tape to avoid grease leakage of the supply and drain oil ports.
