6.3.1. Bearing in each part

 

Vibration/abnormal sound and overload will occur when bearing in each part is damaged. Further, if bearing fixing nut is loose, bearing will have diversion, which may damage bearing.

 

n Diagnostics

 

①    Check whether bearing has diversion by applying force to 1st arm and 2nd arm. (If Chain Block is used, check whether bearing has diversion with reduction gear free of load and 1st arm and 2nd arm in the position.)

②    Check if peripheral equipment has been contacted with robot before the abnormality.

 

n Resolution

 

Replace the bearing. A chain block is needed to lift and hang the robot ARM. Contact our service office for any difficulties.
