2.3.4 Lubrication of Ball Screw Spline Shaft
To lubricate the ball screw spline shaft, use the following grease.
•
FOMBLIN grease (Ex. OT–20 made by Solvay Solexis)
•
DO NOT mistake the type of grease. Otherwise, the robot performance may
deteriorate or the robot may malfunction.
•
After you have touched the ball screw spline by hand, be sure to apply the
grease to it. Otherwise, rust will develop on the shaft.
a)
Check of ball screw spline shaft for lubrication
Open the arm 2 cover and make sure that the ball screw spline shaft has not
run out of grease and that no rust has developed on it. If the ball screw spline
shaft has run out of grease, apply the grease according to Para. b).
b)
Greasing of ball screw spline shaft
Apply the grease with a brush or by hand so that all guide slots around the shaft
are covered. Just after the greasing, DO NOT start an operation. First, move
the ball screw spline shaft slowly over the entire motion range. Then wipe off
any grease that oozes from the shaft.
Repeat this operation a few times.
