instantaneous pressure inside the reducer becomes higher, which may cause
the oil seal of the motor to be damaged and the grease will enter the motor
J3 shaft reducer replacement grease process
Operate the operator to the attitude shown in Table 13-2
To prevent danger, turn off the power, hydraulic and pneumatic sources
connected to the robot
Place the waste oil collection tank near the grease discharge port.
Remove the M10x1 plug of grease discharge port, as shown in Fig. 13-8.
Install the grease drain pipe to ensure the waste oil flows into the oil
sump
Remove the M10x1 plug of grease injection port, install the grease
injection nozzle, and use the manual grease injection gun to inject grease
until the new grease is discharged from the grease discharge port
Release the internal grease pressure of the reducer as shown in table 13-
3
Weigh the amount of grease discharged and the amount of grease
injected, both of which shall be equal; if the amount of grease discharged
is less than the amount of grease injected, inflate the grease injection
port to discharge the excess amount; if the amount of grease discharged
is greater than the amount of grease injected; inject the amount of grease
from the grease discharge port to be insufficient.
Remove the grease injection nozzle, install M10x1 plug at the grease
discharge port and grease injection port, and apply sealing tape / sealant

Caution
When the grease is injected from the grease injection port to the inside of the
operator, the grease injection speed of the manual pump is less than 8g / s,
and the grease injection pressure is less than 0.3MPa. In order to ensure that
the old oil in the reducer can be removed smoothly, after filling for a period of
time, take a rest for a while, and continue to fill when there is no old grease
discharged from the oil outlet. When the oil filling speed is too fast, the
