9.3.2 List of Necessary Items
Prepare necessary items as indicated in
. “S”, “L”, “U”, “R”, and “BT” in the table mean axes for grease
exchange to each axis, and “Casing” means R-, B-, and T-gear in a casing
for grease exchange.
9.3.3 Grease Exchange
9.3.3.1 Grease Exchange for S-, L-, U-, R-, B-, and T-Axes Speed Reducer
1. Before injecting/discharging grease, the posture of the manipulator
must be set. Make the posture as indicated in
Posture of Each Axis While Injecting”
to remove the plugs of the
grease inlets and the grease exhausting ports. (Refer to
Position of S- and L-axis Speed Reducer”
U-axis Speed Reducer and R-, B-, and T-gear in a casing”
fig. 9-7 “Plug Position of R-, B-, and T-axis”
.) If it is difficult to make
the recommended posture because of external cabling or etc., adjust
the posture as much as possible to make the position of grease inlet
located in the lower part and the position of exhaust port located in the
upper part. Thus, grease can be filled/exchanged more properly as the
recommended posture.
