5.1.2. H-AxisReducer

Figure 5.2 H -Axis Reducer Grease Inlet/Outlet

Attention

Injecting grease without removing the plug of the outlet causes an increase of internal

pressure and oil leakage and damages a motor because of the inflow of grease.

It is absolutely necessary to remove the plug.

n Grease Replenishment

(1) Prepare the grease nipple A-PT1/4, and then set the H-axis arm perpendicularly.

(H:90°-Floor Type, H:0°-Shelf Type )

(2) Remove the plug G1/4 of the grease inlet, and fasten the grease nipple A-PT1/4.

(3) Remove the plug G1/4 of the grease outlet.

(4) Inject the grease into the grease inlet using a grease gun.

ü Grease type : VIGO GREASE RE0

ü Amount of grease : 2,175cc (2.0kg, reference value)

(5) The grease replacement is complete when new grease appears in the outlet port.

The new grease can be distinguished from the old one by color.

(6) Move the H-Axis for a few minutes to eject the old grease and then add grease until the

new grease appears in the outlet port.

(7) Discharge excessively fueled grease and residual pressure. (Refer to the discharge

procedure below.)

(8) Remove the grease nipple of the inlet and assemble the inlet plug.

n Injecting grease after replacing the reducer.

(1) Prepare the grease nipple A-PT1/4, and then set the H-axis arm perpendicularly.

(H:90°-Floor Type, H:0°-Shelf Type)

(2) Remove the plug G1/4 of the grease inlet, and fasten the grease nipple A-PT1/4.

(3) Remove the plug G1/4 of the grease outlet.

(4) Inject the grease into the grease inlet using a grease gun.

ü Grease type : VIGO GREASE RE0

ü Amount of grease : 2,900cc(2.6kg)

(5) The grease replacement is complete when new grease appears in the outlet port.

(6) Discharge excessively fueled grease and residual pressure. (Refer to the discharge

procedure below.)

(7) Remove the grease nipple of the inlet and assemble the inlet plug.

n Procedure in discharging excessively fueled grease and residual pressure after grease

replacement and injection

(1) Attach a grease receiver or a hose to the grease outlet to prevent contamination from

discharged grease.

(2) Operate it within a range without surrounding and interference under the following

conditions.

①Operation angle: 90° or more

②Operation speed: 50%

③ Operation time: 20 minutes or more

(3) Wipe the outlet port with a cloth and attach the plug.
