Lubrication of spline screw shaft
4.1.1
Standard robot
Grease usage: Check whether there is grease in the
groove of the spline screw shaft; or wipe the surface of
the shaft with dust-free paper and observe whether the
dust-free paper is reflective on its surface. If no, the grease
is used up.
The use of lubricating oil or grease can effectively extend
the life of the robot.
Running out of grease may cause abnormal wear, noise, etc. Check the grease on the
spline screw shaft regularly. If much lubricating grease is applied or the grease is unevenly
applied, grease dripping may occur.
There will be a slight loss of grease at the part of the spline screw shaft exposed to the
air. Under normal operating conditions, it is recommended that the spline screw shaft be
filled with lubricating oil every 3 ~ 6 months. Select appropriate grease according to the
information in Table 4-1.
