6.3.1. Fulcrum Bearings

 

Vibration, abnormal sound and overloads are observed when a fulcrum bearing is damaged. When the Nut holding bearings becomes loose, bearing play occurs. It may damage the bearings.

 

n  Diagnostics

 

①    Shake the 1st Arm and 2nd Arm back and forth to check if bearing exhibits any play. (In case of using a chain block, check the bearings for the play, with the 1st Arm and 2nd Arm posture maintaining and without any overload to the reduction gear).

②    Check to see if the robot touched other peripheral equipment before the malfunction.

 

n  Resolution

 

Replace the bearing. A Chain Block is needed to lift and hang the robot Arm. Contact our service office for any difficulties.
