1. Wear between the output shaft and the guide copper sleeve
Phenomenon:
a Friction scratches appear on the output shaft
b Copper shavings fall off the lower end of the output shaft
c There is a harsh abnormal sound between the output shaft and the guide copper sleeve.
Reason: a. The roundness or coaxiality error of the output shaft is large, resulting in wear.
b Metal debris fell into the cylinder barrel. Solution: Replace the worn output shaft and guide copper sleeve to ensure that the cylinder barrel is clean.
2. Ball screw is damaged
Phenomenon:
a The output is unstable and the displacement deviation is relatively large.
b There is abnormal noise in the ball screw part
reason:
a Caused by inconsistent processing of workpieces
b Iron filings fall into the screw rod, causing damage to the screw nut. Solution: Replace the screw rod. If the processed parts are not concentric, replace the processed parts.
3. Bearing damage
Phenomenon:
a There is abnormal noise in the bearing part
b The output is unstable and the displacement deviation is relatively large.
reason:
a Iron filings fall into the bearing
b The processing part of the bearing position of the workpiece is concentric
Solution: Replace the bearing. If the bearing position of the workpiece is not concentric, replace the workpiece.
4. Timing belt wear
Phenomenon:
a There is abnormal noise in the belt part
b There is a lot of black belt powder on it
reason:
a The two ends of the installation synchronous belt are not concentric
b There is a problem with the matching of synchronous belt and synchronous wheel
Solution: Replace the synchronous wheel or synchronous belt
